# Best Zero fasting app alternatives for iPhone (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.

## Questions

### Why look for a Zero alternative?

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, per its App Store listing. MyFast, Fasting Week, Simple and YAZIO each cover a different gap.

### Which Zero alternative is free?

MyFast can be used free of charge, with ads and optional purchases. Fasting Week is free to download with optional Premium. Simple and YAZIO have limited free versions.

### Which alternative lets me set a different eating window for each day?

MyFast schedules windows for the whole week, and Fasting Week lets you set each day's eating window and planned meal times. Read more in our guide on planning eating windows by day.
