How to publish your Thunkable Project to the Apple App Store
Last updated
Publishing your app to the App Store can be a rewarding process.
Apple requires a lot information for apps that are available in their App Store. As a result, the publishing process can feel long and will require at least 20 minutes to complete the necessary steps on the Thunkable website, which currently requires information from 4 different Apple websites. We recommend completing the Prepare for Submission steps before starting the publishing process in Thunkable.
Thunkable is continually looking for ways to streamline the publishing process and has made it possible for creators to publish from a non-Mac computer, which is normally required by the standard publishing process.
In this document, the version of your app that you submit to the App Store is referred to as a build.
Apple holds a high standard for apps that are approved for distribution in the App Store so please review Apple's policies and guidelines to make sure your app is in compliance before you sign up for the Apple Developer Program
You will need to set a version number in your project. You can set your version number in the Project Settings panel under iOS > Version Number.
If this is your first time sending this app to App Store Connect, you can set the version number to 1. You will need to increment your version number, or increase it by 1, every time you submit a build to App Store Connect.
Apple requires that you explain to users why you may need access to sensitive services like a camera, photo library and microphone. You can add these explanations in the Project Settings panel under iOS Permissions.
User Tracking If your app shares trackable data with any third parties, you must tell your end user what data is being shared and why. This should be left blank if no trackable data is shared with third parties.

You will need an Apple Developer Account to publish an app to the App Store. To obtain a developer account you must enroll in the Apple Developer Program. An Apple Developer Account costs $99/year.
Certain educational institutions qualify for free Apple developer accounts. To check if your school or university if eligible, please visit this Apple site.
If a developer uses a third-party platform like Thunkable to send an app build to App Store Connect, the developer needs to create an app-specific password.
You only need one app-specific password for Thunkable to send any build to App Store Connect on your behalf.
You do not need separate app-specific passwords for separate Thunkable projects.
You will need this password to send a new build to your App Store listing in the future, so make sure to record it securely.
Go to the Apple ID account website and create an app-specific password.
Step 1: Enter your Apple ID and Password
To change an app-specific password, you will need to revoke your old password and generate a new password using the steps above. To revoke an app-specific password:
Sign into your Apple ID account page
In the Security section, click Edit
Go to the App-Specific Passwords section and click View History
Click the ⓧ next to an individual password to revoke it, or click 'Revoke All' to revoke all of your app-specific passwords
Every app published on the App Store must have a unique name. For example, there can only ever be one app called Thunkable Sample App. You can Register your App ID to reserve the name you want!
Go to the Apple Developer website to register a new App ID. Click through the tabs below to see each screen in the ID creation process.
Step 6 in the tabs below shows you where to find your App Name, Team ID, and Bundle ID.
App Name: The app Name must be unique to the App Store and is what appears next to the app icon when it is downloaded on a user's phone.
Team ID: A unique account identifier that is linked to your Apple Developer Program membership. Apple will automatically create this for you, and it can be used for every app you publish.
Bundle ID: Also unique to your app, but not visible to your app users. Otherwise, a single Explicit App ID should work. Apple recommends reversing your domain name to create your bundle ID i.e. com.yourDomainName.yourAppName to avoid conflicts with other apps.
Note: Starting June 16, 2020, uploading apps to the App Store requires an explicit bundle ID. Wildcard bundle IDs are no longer available when creating app records.
Open your Apple Developer account page and choose the Certificates, IDs & Profiles option from the menu on the left hand side of the screen.
Once you have registered an App ID, you can create an app listing on App Store Connect. This is where you will manage your submission to the App Store.
Go to the App Store Connect website and follow the steps below to create your App Store listing with the App Name and Bundle ID you registered earlier.
Click My Apps to create a new app and to manage your existing apps.
Now click on your app name to prepare your store listing.
Thunkable enables you to send your build directly to the App Store without the need for any specialized software or hardware. To begin the process, click on the Publish icon and choose Publish iOS from the drop-down menu.
A publishing dialog will pop up to guide you through the publication process. Please take a moment to read all the instructions.
Click the Get Started button to proceed.
Enter the Apple ID that is associated with your Apple Developer account. Click the Next button to proceed.
If you did not register an App ID before getting started, now is the time to do so.
In the next tab, you will be prompted for your App Name, Team ID and Bundle ID. If you are unsure of what these are, please refer Register an App ID on App Store Connect, above.
This step should only need to occur once. Although you need a different provisioning file for each project, your Account Certificate should remain the same between any projects published with Thunkable. Once you issue a new certificate, that will be good for a period of 1 year from the date of creation. You should be able to publish as many apps as you want with that 1 distribution certificate for you (the publisher) and 1 provisioning file per app (per published Thunkable project) A certificate is specific to the email account that was used to create the certificate. I.E. If you are helping another Thunker publish their app, you would need to log in and publish from that users account using their certificate.
Two-factor authentication helps to keep your account secure and Apple has made it mandatory for new developers to turn two-factor authentication on. If you do have 2FA turned on, you'll need to complete the following steps to confirm your identity with Apple.
In the publishing dialog, click the link that says Click to Download CSR. This is your Certificate Signing Request file and you will need it to generate an iOS Distribution Certificate.
Go to the Certificates page in your Apple Developer account to generate an iOS Distribution Certificate.
You may already have an account certificate in your account. You can only have two certificates per account so you may need to revoke a certificate before you can create a new one.
Click on the blue + icon to create a new iOS distribution certificate.
Provisioning profiles are required by Apple to install an app on a device. You need to create a .mobileprovision file in your Apple account and then return to Thunkable to upload this file.
Open up the Profiles list in your Apple Developer account and click the blue + button to get started.
Back in Thunkable, upload your .mobileprovision file and click the Next button to proceed.
Paste your app-specific password into the empty text box and click the Next button to proceed.
If you did not create an app listing on App Store Connect before getting started, now is the time to do so.
You're almost there! Review your app icon and your Build Number and Version Number.
App icon: This app icon appears when a user downloads your app from the App Store. Our recommended size is 192 x 192 px. This icon must not have any transparent pixels.
Build and Version Numbers: The version number is visible to your users when they download a new version of your app. The build number needs to increase with each version and is only visible to you. You can opt to let Thunkable automatically increment your build and version numbers.
You should shortly receive an email from Thunkable to let you know that your build is being sent to the App Store. There are still a number of steps that you need to complete on App Store Connect before your app can be published, but that's everything completed from the Thunkable side of things - congrats!
You will need to provide some information to Apple about your app before it can be reviewed and published.
You should receive an email from Apple that says your app is ready in the App Store Connect website. This may take up to an hour.
To view your build:
Go to your App Store Connect dashboard
Select the app listing of the build you have just uploaded
You will see the app listing homepage. This page contains the tabs App Store, Features and TestFlight.
If your build is submitted successfully, it should appear under the TestFlight tab in this app listing homepage. TestFlight is a tool from Apple that allows you to test your app before it is submitted for release in the App Store.
(If there are any issues, you’ll get an email from us telling you what you’ll need to fix.)
Back in the App Store tab, scroll down to the section titled Build and click the button that says Select a build before you submit your app.
You will see a dialog that allows you to select a build to attach to this app listing. Select your chosen build and click Done.
Now you can review the App Information included in your App Store tab. You can review Apple's advice on filling in your app information on this webpage.
Set a price point for your app. Apps can also be distributed for free.
The final section requires screenshots for both iPhone and iPad and a high resolution icon.
The high resolution icon will be featured in the App Store listing and must be 1024 x 1024 px with no transparency. To generate this icon, we recommend a tool like this.
You can see the screenshots you need in Apple's screenshot specifications document.
You can create your own iOS screenshots in your browser. Learn more here: Generate Screenshots
You may need to answer a question about export compliance. Select Yes when asked if your app uses encryption.
After submitting your app for review, you may asked, "Does this app use the Advertising Identifier (IDFA)?"
The app will still be able to be published but you will want to check the following three boxes:
Note, you should not check the box labeled Serve advertisements within the app.
Now your app listing is ready for Apple to review!
To update an existing App Store listing, follow the instructions on Apple's website here.
For Step 6, Upload your new build to App Store Connect, follow the instructions in Send a Build to App Store Connect.
You do not see your app uploaded to App Store Connect
Download. One way to check if your app is build-able is to download it to your phone first. Two common download errors are:
You uploaded an icon that has the same name as an existing asset that you have uploaded
Your app icon is not an image file
Icons. Apple additionally does not allow you to have any icons with any transparent colors. We recommend app icons to be 192 x 192 px
Membership. To publish to the App Store, you'll need to sign up for Apple Developer Program Membership. This currently costs $99 / year.
App Store Connect. Make sure to follow this step on creating a new app on iTunes Connect
Certificates. If you have an existing Apple Developer Program account with 2 iOS certificates, you'll have to revoke one. Apple only allows developers to have 2 iOS certificates at a time and Thunkable creates one when it publishes to your account
Provisioning profile. After you revoke your certificate, it is possible that one or more of your provisioning profiles will become inactive. To publish successfully, you'll also need to delete any inactive provisioning profiles
Login. Apple ID or password were entered incorrectly. Since we don't store either one, there's no easy way for us to check so enter it slowly
Apple ID and privacy terms. You must accept Apple's new Apple ID and privacy terms.
You see a message saying "ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use UIWebView APIs". This is a warning, but you can still publish your app. See the Web Viewer documentation for more details.
Your app on iOS is inaccessible and your end user sees an error screen saying your app is unavailable.
You switched to the Free plan.
Your App (Bundle) ID doesn't match your Active Bundle ID and you may need to enable it in your Account Settings before the app can be used.
Go to the settings page to see your published Bundle IDs. You will see how many published apps you have available and be able to select which published app you wish to keep active.
Changes can take up to 24 hours to be applied. If you change the status by mistake please change it again as soon as possible to avoid issues.
To publish an app to the App Store that contains Push Notifications, you need to:
send an app that does not contain Push Notifications to App Store Connect
add push notifications to your app project (see instructions here)
send the new version of your app to App Store Connect
Between sending these two versions of your app to App Store Connect, you will need to create a new .mobileprovision file. Here's a quick overview of what that process looks like.
Click on Provisioning Profiles > All to see your current iOS provisioning profiles. Notice that the app you just created is now invalid so we need to generate a new one.
Open the inactive profile and click on Edit to generate a new one.
Scroll to the bottom of the page and click Generate.
On the next screen, click the Download button and the .mobileprovision file will be saved to your downloads folder.
If you want to remove your apps from being listed in the App Store, open your app listing on App Store Connect and follow these instructions:
On the “App Store” tab, click on “Pricing and Availability”
Click the “Remove from Sale” radio button
Then click the “Save” button to unpublish your app
You can see these buttons in the screenshot below:
Please note that if your Apple Developer account expires, your apps will no longer be available for download in the App Store.
Removing your app from the Play Store will not delete it from devices which have previously downloaded the app.
