1. Zero
Zero is primarily a fasting app that offers a clean and user-friendly interface. It supports various fasting protocols, including 16:8, OMAD (one meal a day), 5:2, and alternate-day fasting (ADF). While it excels in tracking fasting windows, it lacks an extensive food database for calorie logging, which means users often need to rely on external apps for detailed nutritional information. The app is free to use, but a premium subscription ($69.99/year) unlocks advanced features like personalized insights and a community forum.
Trade-offs
- Pros: Excellent fasting timer, user-friendly interface, supportive community.
- Cons: Limited food database for calorie tracking, premium features can be costly.

Simple combines calorie tracking with an AI coach that personalizes your fasting experience. It supports 16:8, OMAD, and 5:2 protocols. The app provides a fasting timer and allows users to log their meals easily. The AI coach offers tips and motivation based on user behavior, which can be helpful for maintaining adherence to fasting schedules. The app has a free tier, but premium features are available for $39.99/year.

- Pros: AI coaching, motivational features, integrated meal logging.
- Cons: Limited fasting protocol options compared to others, premium features may not justify the cost for all users.

It offers voice logging and AI photo logging during eating windows, making meal tracking faster and more intuitive. The app supports all major fasting protocols (16:8, OMAD, 5:2) and boasts a registered-dietitian-verified food database with less than 5% error. The comprehensive free tier allows users to access essential features without a subscription, though premium options are available for more advanced analytics.
