Fasting Week vs Simple: which app should you use?

Which is better, Fasting Week or Simple?

Choose Simple if you want an AI coach and quick logging of food (including from a photo), water, activity and weight, with Apple Health and Apple Watch integration; Fortune named it its overall intermittent fasting app pick. Choose Fasting Week if you want to plan each day's eating window and meal times for the week, write down when you actually ate, start a fasting timer yourself, and keep protein, water and weight logs on your device with no account and no ads. Simple's paid tiers are subscriptions, and its current version needs a recent iOS release; Fasting Week runs on iOS 15.1 or later and its Premium is optional. Fasting Week has no Apple Health sync yet. Neither app is medical advice.

Questions

Is Simple a fasting app or a diet app?

Both. Its current App Store listing presents it as an AI weight loss coach with food, water, activity and weight logging, and Fortune covers its fasting and hydration tracking. Fasting Week focuses on planning eating windows and a meal journal.

Does Fasting Week have an AI coach?

No. Fasting Week is a planner and journal; it does not give advice on how long to fast.
