Frequently Asked Questions
How do I start a fasting period?
Simply open the app and tap the large "Start" button in the center of the screen. Your fast begins immediately and the timer starts automatically.
How do I change my fasting goal?
In the top right corner of the app, you'll find an hourglass icon for the fasting goal. You can choose between 12:12, 16:8, 18:6, and 20:4. Alternatively, you can manually enter the fasting goal by tapping on the end time.
Is my data stored in the cloud?
By default, all data is stored locally on your device only. If you have iCloud enabled, your fasting periods are optionally synchronized between your Apple devices. This data is encrypted in your private iCloud.
How do I enable Dark Mode?
FastUp automatically follows your iPhone's system settings. When you enable Dark Mode in iOS settings, FastUp will automatically display in dark mode. Alternatively, you can manually enable Dark Mode in the app settings.
How do I delete my data?
If you uninstall the app, all locally stored data will be deleted.
Why am I not receiving notifications?
Make sure you have enabled notifications in the app settings.
