Best Zero fasting app alternatives for iPhone (2026)
What are the best Zero fasting app alternatives for iPhone in 2026?
The best Zero alternative depends on what you are missing: MyFast if you want a weekly fasting schedule that is free to use with ads and optional one-time purchases, Fasting Week if you want to plan a different eating window for each day and keep a meal journal, Simple if you want an AI coach with food logging, and YAZIO if you want calorie and macro counting with fasting. People look beyond Zero because protein score, water tracking and custom fasts sit in Zero Plus, free users get three meal logs, and one reviewer said basic timer use needed payment after a subscription lapsed. Fasting Week logs protein, water and weight, needs no account and shows no ads; Premium is optional, and it has no Apple Health sync yet. Not medical advice.
