What is the Thunkable Live App?

The Thunkable Live app connects the projects in your web browser directly to your mobile device. It allows you to do two things:

1. You can Live Test your project. Any changes you make in your browser are displayed on your device immediately.

2. You can Live Preview any of your projects, directly on your device, without the need to be logged in to your computer.

Download the Thunkable Live App

The Thunkable Live app allows you to live test your app on your device, in real-time, while you are building it. Not even hard core developers have this super power. You can also preview all your app projects from the comfort of your mobile device.

If you don't have an iOS or Android device, you can also set up an emulator on your computer that will mimic what you would see on an actual device.‌

With Thunkable Live installed on your device, you are now ready to live test or to live preview.‌

Live Test

While live testing, any changes that you make to your project should be reflected in your app. Bear in mind that the Thunkable Live app doesn't check your project for errors. Some changes that you make may crash the app. If this happens simply exit out of the app and re-open it.

Getting started

From any of your Thunkable projects, click on the Live Test button at the top of the screen to begin live testing.

‌The next pop-up you see depends on whether you select to sign in with Google or to sign in by email.‌

If you select to sign in with Google:

Clicking on the Live Test button will remind you to open Thunkable Live on your device.

Sign in with the same Google account in Thunkable Live to preview your projects directly on your device.

If you select to sign in by Email:

When you click the Live Test button you will be prompted to enter a code into your computer.

To find this code, open Thunkable Live on your device and click Email sign in - Generate Test Code.

Enter this code into the first prompt and you will be able to live test your app.

Live Preview

For the first time, you can live preview all your app projects from the comfort of your mobile device. Simply login and you should see a list of all your projects on your Thunkable Live app.

Troubleshooting

Common issues with the Thunkable Live app

You see a blank / white screen when you live test (even if there are items in your app)

• If you have a Navigator as the first item in your tree, make sure your screen is dropped within it

• You have unconnected blocks

• You have an event triggered by a Screen. Start which may be causing the screen to crash

• Your app and desktop may not be logged into the same account

App is crashing because of a bug on our end; we are trying to fix it as soon as we can

• (Android only) You are trying to set the value of a Slider in your blocks

• (Android only) You are trying to set the latitude and longitude of a Map in your blocks

Image is not showing up on your phone

• The height or width of the image may be set to 'Fit contents'

Preview your App on the Web

Preview on the Web allows you to live preview your own project directly from your browser. Simply click on "Live Test" to preview your own app in a pop-up window.

You can also preview any public app, directly from the Project Detail Page. Here's one example, but you can find thousands of others in the public gallery.

Web Preview

You can test and preview your project directly within your browser. This is a great option when designing your app's user interface and building out the app's functionality with blocks.

It is important to note, however, that Web Preview does not support some app features. This is because some app features require functionality only available on a mobile device, such as push notifications, accelerometer, and Bluetooth low energy. For a full list of features that cannot be tested with Web Preview, please see here: Publish as a Web App.

Unsupported Components

Not all components are supported on the web at this time so please see the list below of components that are not supported:

One Product, Two Interfaces

The first thing you need to know as we welcome you to our Thunkable Docs is that we have two libraries of documents. One for each of the interfaces we currently offer:

Drag and Drop

Drag and Drop is our new platform interface that took our Creator's favorite features and functions from the previous interface (Snap to Place) and improved on them.

You'll know if you're looking for support with the Drag and Drop interface if your screen looks like this:

Snap to Place

Snap to Place was our first foray into cross-platform app development. It is our old platform interface.

You'll know if you're looking for support with the Snap to Place interface if your screen looks like this:

You're in the right place if you're looking for the Thunkable Docs supporting our Snap to Place interface.

When you first sign in to Thunkable you will be prompted to create a project. To learn more about the maximum size your projects can be, please see our article about the for apps.

Other articles in this section

Public Projects

Public projects are included in the for anyone to preview, download or remix. If you create a public project, please know that it can be viewed by anyone in the Thunkable community.

Private Projects

Private projects are just that, private. They can only be seen by their app creator and do not get included in the Only Thunkable users with a paid plan can create and share private projects.

Making Projects Public or Private

To make your projects public or private, clicking the vertical ellipsis associated with a project reveals its project menu. You can then select Project Detail Page and switch to change who can view your project.

You can also click into your app settings in your project and toggle the switch to set your project to public or private.

Read-Only projects

Private projects become Read-Only projects when a Thunker's paid membership expires. Read-Only projects remain private and are not included in the Thunkable Gallery.

You can only preview Read-Only. Once a project has been switched to Public, you cannot switch it back to Read-Only.

Step 1. Sign in to Thunkable

Thunkable gives you a variety of ways to create your very own cross platform apps. To learn how to set up a Thunkable account, please read our article on signing in.

Step 2. Check out your Thunkable Projects page

Choose how you want your projects to be laid out. Search and filter your projects.

Step 3. Try Our Tutorials

They exist! They are helpful! Thunkable tutorials cover both basic concepts and advanced features.

Step 4. Download the Thunkable Mobile App

With the Thunkable Live mobile app, you can preview your apps directly on your personal devices. To learn more, please click below.

Click on one of the links below to download the Thunkable mobile app.

If you don't have an iOS or Android device, you can set up an emulator on your computer that will display your apps.

Step 5. Components

We have custom components and third-party integrations that you can drop directly into your projects. These components will allow you to build more advanced features.

Step 6. Blocks

The language of blocks is a visible programming language. By dragging and dropping blocks together, you can program your app.

It's best to keep app sizes as small as possible to preserve space on people's devices. All app projects have a 50MB limit, and free Thunkable accounts have a 100 MB total storage limit. If you need more storage for your account, you can upgrade to our Builder plan to get 1 GB of space for your projects or to Advanced to get unlimited space.

Limits

You can view a project's app size on the project's details page:

The main contributor to an app's size are files (also known as assets). To add or delete files, click on the Assets button in the side bar. Then click the "+" icon to manage all the files in your project.

Operating Systems (OS)

Thunkable recommends and actively supports mobile operating systems that receive security updates.

This includes iOS 16+ and Android 12+.

Thunkable apps are often compatible with older OS, but this is not guaranteed.

Account storage limits

You can view your total account storage size in your account settings.

Free Thunkable accounts have 100MB of storage.

Builder Thunkable accounts have 1GB of storage. Advanced Thunkable accounts have unlimited storage.

Read more about Thunkable plans here.

If you are near the limit, you may be able to create additional storage by removing projects that you no longer need like an old version or copy of a project.

Maximum recommended asset size

We recommend that each of your asset files not exceed 50KB -100KB. Using smaller file sizes in your project will result in faster loading times for your users.

Naming Your Assets

Thunkable recommends using file names that do not contain whitespace characters.

Here are two naming methods we recommend:

1. Snake Case - each space is replaced by an underscore (_) character, and the first letter of each word written in lowercase.

   • example_one.png

   • here_is_another_example.html

2. Camel Case - writing phrases without spaces or punctuation, indicating the separation of words with a single capitalized letter, and the first word starting with either case.

   • exampleOne.png

   • hereIsAnotherExample.html

What's a Component?

Apps contain many different features.

On Thunkable, you get to drag & drop which features - which we call components - go into your app.

Some features you can see. Let's call these features visible components. Examples include buttons, loading icons, and images.

Some features you can't see. Let's call these features invisible components. Examples include sounds, timers, and databases.

Visible Components

To put it simply, visible components are features that you can see on your app screen - like the ones pictured above.

Visible components can be styled by size, text, space, and location.

When adding visible components into your app, please note that they can only exist on one screen at a time. For example, if you want to add a button to three different screens, each screen will require its own button.

Invisible Components

Invisible components are features on your app that you can't see.

They often relate to your app's functionality, and are quietly running in the background. When you add an invisible component to your app, that component can work on any screen.

For example, if you add a database component to your app, the database can be accessed from any screen. You do not need to add a database component to each screen.

Invisible components are displayed underneath the mobile device on the Thunkable app builder.

Finding Components

Components are organized into 10 different categories. For a more detailed description of each category and an outline of the components they contain, click on one of the pages below.

To find a component, you can manually scroll through the components section on the Thunkable app builder. You can also expand and collapse categories depending on your needs.

The quickest way to find a component is by searching for it in the search bar. Any matching components will also be displayed as you type.

The Component Tree

The component tree can be found at the top left corner of your screen, just below your project name. The component tree contains a list of the visible and invisible components in your app.

You can move components around on the component tree to change the location of a component in your app.

Components that are nested can also be expanded and collapsed by clicking on the ▾ icon.

Thunkable is building the world's largest gallery of open sourced apps to help inspire you and save you time.

(Private) Social Media

Social media was originally invented for people to share things with people they trust. With the evolution of popular platforms today, it's increasingly hard to simply keep our channels private enough so our conversations and photos are less filtered and bringing us all joy (instead of FOMO).

Snap Gram

This app is kind of like an Instagram and Snapchat hybrid and we've created a private version of this app that we are using daily at the Thunk Tank to help our global team feel more connected. To make your app private, simply create a free Cloudinary image account to keep your images within your sights and a free private Firebase Database to host the links to those images. You won't believe what people will share with a little bit of privacy!

Avoid using the character "&" in your app name: at the moment, it prevents your app from being installed on your device

Project Name

App (Bundle) ID

This should follow a pattern like com.domain.creatorname.appname

Make sure none of the segments of this package name begins with a number. Make sure none of the letters in this package name has an accent (e vs ë).

Icon

Your app icon is the picture that represents your app on your mobile device. This icon will also appear on your listing in the Google Play Store or App Store, and as your project icon on Thunkable.

Please make sure that the file you upload does not have the same name as another asset that you are using for your app. This will cause an error.

Add Items to a List Viewer

Short Lists

We recommend adding a short list of items within the app itself as the Screen starts. Although the list block itself can handle a large number of items, practically speaking you probably only want to use this approach if your project has tens of items.

Medium Lists

If you need longer lists of information in your app you can use delimited data. This is very similar to using something like a .csv file. You can have hundreds of items in your list viewer using this method.

Long Lists

For longer lists where you need hundreds or thousands of items in your list, we recommend using the Data Sources component. This gives you three different options for storing your data.

1. Local Table

2. Airtable

3. Google Sheets

Choosing Airtable or Google Sheets allows you to create dynamic list viewers. This is where the information displayed to the user changes whenever you change your cloud-based data in Airtable or Google Sheets. Either of these options are ideal for when you need to store thousands of items, or you need to work with items that change frequently.

Select Item from a List Viewer

Style the List Viewer

You can customize the List Viewer with the following properties:

• Text Items Color: Set color of Text Items font

• Text Items Background Color: Set background color for List Viewer

• Text Items Font Size: Set font size of Text Items

• Show Arrow: To see an arrow beside each item in the list, set the switch to true

• Visible: To see the text input in your app, set the switch to true

• Border

  • Width: Enter how wide you want the border outline of the List Viewer to be

  • Color: Pick a color for the border of the List Viewer

  • Style: Select if you want the border to be a dotted, dashed or solid line

  • Radius: Enter how round you want the edges of the border for the List Viewer to be

Edit the ListViewer Height

A List Viewer automatically fill 100% of the Screen width

You can set how tall the List Viewer is using the height property.

Height

• Fill container - The List Viewer fills the entire screen vertically

• Fit contents - The List Viewer’s height changes to fit the contents it contains

• Relative size - The List Viewer fills the specified percentage of the screen

• Absolute size - Sizes the List Viewer to a specified number of pixels

Add Spacing

Loading Icon Overview

For activities that take more than a few seconds, loading icons can be helpful to tell your app users that an activity is happening in the background, such as retrieving or uploading data.

Style the Loading Icon

Showing and Hiding the Loading Icon

The loading icon should be displayed when the app is performing an activity in the background and hidden when it is not.

One way to show and hide the icon is to use the visible property of the component.

In the following example the loading icon shows up when the app opens but disappears after data is retrieved from Airtable.

When the visibility is set to true, the loading icon will be seen on the app screen. If set to false, the loading icon will not be seen on the app screen.

Add a Data Viewer List or a Data Viewer Grid to your app in order to connect to your data source:

You can design custom layouts for displaying your data:

You can use blocks to let your user create, read, update and delete information in your data source by interacting with the Data Viewer, using Data Sources blocks:

Overview

While the Data Viewer List and Data Viewer Grid have different layout options, you may want to design a custom layout for your data. This can be achieved with Row and Column components.

Video Tutorial

How To Use a Custom Layout in Your App

Design your Custom Layout

Use a Row or Column to create the custom layout you want. We will refer to this as the 'Parent Row/Column' for the rest of this doc.

This layout is a Row that contains two Columns. The first Column contains 3 Labels: TitleLabel, DescriptionLabel, and PriceLabel. The second Column contains an Image, ProductImage, and a Rating, called ProductRating. These components will be referenced in subsequent screenshots in this document.

Save your Custom Layout

Select your Parent Row/Column and click the 'Save as Data Viewer Layout' button.

Basic

When you click Save as Data Viewer Layout, you will see the following dialog:

To save a basic Data Viewer Layout:

• Enter a Layout Name

• Select if your Layout Type is List or Grid

• Let Advanced Binding be set to false

• Click OK

Advanced

To save an advanced Data Viewer Layout:

• Enter a Layout Name

• Select if your Layout Type is List or Grid

• Set Advanced Binding to true

You can now select which properties of the components in your Parents Row/Column you want to bind to the values in your Data Source.

Once you have selected all of the properties that you want bound to the values in your Data Source, click OK to save your custom Data Viewer layout.

Use Your Custom Layout

Once you have saved your custom layout, you can select it as a layout for your Data Viewer. If your layout was saved with the Layout Type List, it can be used with the Data Viewer List. If it was saved with the Layout Type Grid, it can be used with the Data Viewer Grid.

Bind Your Data to Your Custom Layout

You can bind the properties of your data to a Data Source.

Basic

With Basic Data Binding, Thunkable will automatically select basic properties of your components to bind to values in your data source.

Advanced

With Advanced Data Binding, Thunkable will allow you to bind the properties that you specified to your data source:

Managing your Custom Data Viewer Layouts

You can manage your custom data layouts by going to your Thunkable homepage at x.thunkable.com/projects and clicking on the Data Viewer Layouts tab at the left of the page. From here, you can edit and delete your custom data layouts.

The Data Sources blocks allow you to perform a variety of CRUD (Create, Read, Update, Delete) operations on records that you have stored in Airtable, Google Sheets or Local Tables.

Add a Data Source to your App

To access the Data Sources blocks you need to add a Data Source to your app. There are two ways to do this:

• Add a Data Viewer List or a Data Viewer Grid to your project

• Click on the ⊕ icon in the Data Sources section of your component tree:

In the modal that appears, you can choose a previously connected Data Source, or add a new Data Source.

Adding a New Data Source

When adding a new Data Source, you can choose between Create your own table, Airtable or Google Sheets as the source of your data.

Add Filter View

1. Open a data source.

1. Click Add Filter View.

4. Refresh your page to ensure the data is reflected in web preview or via the Thunkable Live app.

Authorization Header For Block

If your app uses web API blocks to communicate with Airtable, you must also incorporate the "authorization header for" block into your app. This block retrieves a valid token that can be used as the authorization header in web API blocks.

To use the "authorization header for" block:

1. Ensure your project is connected to an Airtable data source by OAuth.

2. Navigate to your project's blocks tab.

3. Under the App Features heading, click Data Sources.

4. Drag and drop the "authorization header for" block into your workspace.

5. Use the block's dropdown menu to ensure the correct data source is selected.

Google Sheets

In Google Sheets, the entire document is considered to be the data source.

In order to use a Google Sheet as a Data Source, the first row in your Sheet must be a header row.

Your Google Sheet must be shareable for Thunkable to access its data.

To connect a Google Sheet, sign in and grant permission for your Thunkable project to access your Google Drive.

Once you have allowed this, you will see a list of spreadsheets in your Google Drive. If you don't seen the sheet you are looking for you can switch to list view, sort alphabetically or search for the one you need. Click Select to return to your Thunkable project.

At this time, connecting to .xlsx files that are hosted on Google Sheets is not supported. You can convert your .xlsx file to a Google Sheet before connecting it to your Thunkable app project. Simply open your .xlsx file on Google Sheets, then click File > Save as Google Sheets.

Data Source blocks

Create

The create row inblock allows you to append new rows to the end of your data tables.

The inputs are dynamic so if you change the name of Column 1 or Column 2 in the designer these changes will be reflected in the block too.

There is a second create row in block which allows you to add a row in your data source using an object. The field is the column name and the cell info is the value you would like to set.

Read

The get value from blocks allows you get read one value from a specific cell in your data table. You can specify the column name and the view in the block itself and pass the unique row id as an input.

Get row object will return the row object of the specified row ID. The row object can be used with Objects blocks.

The get row object from block returns the row object of the first row that meets the specified condition. You can specify the column name and condition in the block itself and pass the value as an input. The row object can be used with Objects Blocks.

The list of values in block allows you to read an entire column of data from a table and returns it as a list that you can then manipulate with the built-in List blocks.

The number of rows in block returns an integer corresponding to how many rows are in a given table.

The columns in block returns the column names of a data source.

Update

The update value in block allows you to modify or update an existing cell in your data source. The column name and view are specified in the block itself. The row id and new value are passed as inputs.

There is a second update row in block which allows you to update a row in your data source using an object. The field is the column name and the cell info is the value you would like to set.

Delete

Delete Row

You can use the Delete Row block to delete a row of data from your Data source. The row id is passed as an input. If there is an error, the error message is passed as an output.

Delete All Rows

You can use the delete all rows block to delete all rows in your data source. If there is an error, the error message is passed as an output.

Filter

Update Filter For Block Overview

The update filter for block allows you to edit the value for each condition within a specific view of your data source.

From Idea to App

To go from an idea to app, we strongly recommend that you sketch out your vision using the below app templates. It's important to first create a roadmap for how people will interact with your app.

1. Bottom and Top Tab Navigators - These navigators allow you to change screens by clicking on icons at the top or bottom of the screen.

2. Drawer Navigators - A navigator that pulls out a side menu of different options to choose from.

3. Stack Navigators - Navigators that allow you to stack screens on top of other screens.

Layout Components

Overview

The data viewer components allow you to create beautiful user interfaces for your data. All of this is done in just 3 steps, no blocks required!

1. Pick your Data Source

2. Choose your Item Layout

3. Set your Data Bindings

You can add additional functionality to the Data Viewer List by using the included component blocks or you can work directly with your raw data by using the Data Sources blocks.

Data Source

To begin using the Data Viewer you need to specify where your data are stored. Thunkable gives you three different storage options.

You can use Google Sheets or Airtable to store data in the cloud. Alternatively, you can create your own table. This is ideal if you want local, offline access to your data. Creating your own table is also the fastest and easiest way to get started with the data viewer.

In the Data_Viewer_List component properties, click the Add button. In the pop-up modal you can choose an existing data source. If this is your first time using the Data Viewer you can create a new one by clicking on the Create New button.

In the next modal, choose between Create your own table, Airtable or Google Sheets as the source of your data.

Create your Own Table

Start by naming your data source.

Next, select the Data Viewer component and click on the link that says Click here to edit the data. This allows you to edit the placeholder data that was automatically generated
