Live Test your App

Preview your Thunkable project with our Thunkable live app, or on the Web

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:

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

Download for Android

Download for iOS

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.‌

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

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.

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.
