Frequently Asked Questions
How do I start a fasting session?
Open the app and tap the large "Start Fasting" button on the main screen. The ring timer will begin filling, showing your elapsed and target hours.
Can I switch fasting protocols?
Yes. Tap the protocol selector at the top of the main screen and choose 16:8, 18:6, 20:4, OMAD 23:1, or set a custom duration.
Will I lose my data if I uninstall the app?
Yes. All fasting data is stored locally on your device only. Uninstalling the app permanently removes all saved sessions.
Does the app sync between devices?
No. SimpleFast is fully offline by design. Your data never leaves your iPhone, which means no sync between devices.
Why isn't my notification showing up?
Make sure you allowed notification permission when first prompted. You can verify this in iOS Settings → Notifications → SimpleFast.
Is this app medical advice?
No. SimpleFast is a timer tool only. It does not provide medical, dietary, or weight-loss advice. Please consult a healthcare professional before changing your eating patterns.
