Troubleshooting

  1. If the app cannot be installed or opened, confirm that the device runs iOS or iPadOS 18.0 or later and has enough free storage.
  2. If lesson animation, narration, or subtitles do not play correctly, leave and reopen the lesson, then check device volume, Silent Mode, and the in-app language setting.
  3. If learning progress is missing, confirm that you are using the same device and the same app data. Deleting the app from the device removes local learning records.
  4. If Fingertip Earth AR cannot show the camera, record sound, or save media, check the app's Camera, Microphone, and Add Photos permissions in system Settings.

03 / FAQ

Frequently Asked Questions

Does Sapling Isle require an account or a constant internet connection?

The current version does not require an account, and installed lessons and interactive experiments work offline. Opening the App Store review page, sending feedback email, or using system features such as AirPlay may require a network connection or the relevant system service.

Where is learning progress stored?

Lesson progress, completed units, the learning path, and language preference are stored in the app's local data on the current device and are not synchronized to a developer server.

Why does the app request Camera, Microphone, or Photos access?

Fingertip Earth AR uses the camera to recognize a finger and display augmented content. The microphone is used only for video recording when permission is granted. When you take a photo or finish recording, the app asks to add the result to the system photo library.

How do I delete learning records and captured media?

Deleting the app from the device removes learning records stored inside the app. Photos and videos already saved to the system photo library must be deleted in the Photos app.
