Fasting Week vs Zero: Fasting & Food Tracker

Updated · ODEL makes Fasting Week; Zero: Fasting & Food Tracker is by Zero Longevity Science, Inc..

Which is better, Fasting Week or Zero: Fasting & Food Tracker?

Choose Zero if you want a widely used fasting timer with streaks, learning content and an Apple Watch app; choose Fasting Week if your eating window changes during the week and you want to plan it and keep a meal journal. Zero's free tier covers timers and trends, but protein score, water tracking and custom fasts need Zero Plus, and free users get three meal logs. Fasting Week lets you set each day's eating window and planned meal times, save a seven-day plan, record actual meal times and notes, start the fasting timer yourself, and log protein, water and weight. It needs no account and keeps records on your device, but it has no Apple Health sync yet and is iPhone only. Neither app is medical advice.
