Download Your App on iOS
Downloading your app to an iOS device requires an Apple Developer account. The process involves actions in your Thunkable project and your Apple Developer account. We recommend having each open in a separate browser tab so you can easily navigate between them.
Please note that while the images and instructions from the Apple Developer account are accurate at the time of this doc’s publishing, they may change slightly over time.
To avoid download errors, we recommend adding an App Icon and Name to your project before downloading.

You must specify registered devices in your Apple Developer account to create a provisioning profile for app testing and ad hoc distribution. This process is necessary because iOS devices have security mechanisms in place to ensure that only authorized apps are installed and run on them.
Removing a registered device from your account will continue to count against your device limit. At the start of your new membership year, Account Holders and Admins can remove listed devices and restore the available device count.

Every iPhone, iPod touch and iPad has a unique identifier number associated with it, known as a UDID (Unique Device ID). This is either a 40-character alphanumeric ID on older devices or a 24-character ID (excluding hyphen) on newer devices, consisting of eight digits, a hyphen, and 16 alphanumeric characters.

If there are issues with your app build, you will receive an email outlining what you need to fix.
If you receive an email saying that your app cannot be built, it may be the result of one of the following:
- Ensure your app icon image:
- does not have the same name as another project asset
- is an image file
- does not contain transparent pixels. Apple does not allow icons with transparent colors.
- Ensure your App (Bundle) ID adheres to the following:
- It is a series of short strings of text separated by periods (e.g. com.thunkable.creator.app).
- It is all lowercase.
- It begins with a letter.
- Ensure your asset names only contain Roman alphabet characters (with no accents) and numbers.
- Examples of asset names that could cause errors: image(1).jpg, imãge.jpg
- Examples of asset names that won't cause errors: image1.jpg, image.jpg
- We are having trouble with our build servers. Please try again in 30 minutes.
