Application crashes / errors on a mobile device

If you are seeing application crashes, there are a couple of steps you can try to resolve these issues:

  1. Close high memory applications - application crashes on a mobile device are usually due to high memory usage, and closing background applications can help free memory. For Android devices, there are some step by step instructions at:
    and for iOS at:
  2. Reboot the device - rebooting can also free system memory and may resolve the issue.
  3. Reset AppSheet
  4. Update your OS - there may be an operating system update that resolves the issue. For Android devices, you'll need to check with your device manufacturer (Samsung, LG, HTC etc.). For iOS, there are instructions at:
  5. If that didn't work, and your crashes are related to photos on Android, try reducing the photo resolution in your photos application. The following is an example of how to do it on a Samsung Galaxy phone. Other camera apps on other phones work differently, though most should have the option to change resolution. If you are capturing a large number of photos, you can also try lowering the "Image Upload Resolution" setting on the UX > Options page. 

If the steps above haven't resolved your issue, please contact us at When you contact support, please let us know which device you are using and what OS version you're running. For example, "Samsung Galaxy S6 running 5.1.1" or "iPhone 6 Plus running iOS 8.3".

It will also help us to know if the crash reproduces in a web browser on your device. To test this, open Chrome on your Android device or Mobile Safari on iOS. From the browser on your device, login to In the "My Apps" section of the website, click "Preview" for your app, then "Fullscreen". This should start your app in your mobile browser. Use your app as you normally would and let us know if you see the problem while running in the browser as well.
