Decide what to record
Start with the thing you plan to do most days. Decide whether you need a guided plan or a place to record timestamps and notes.
Five apps at a glance
These are the main workflows described on the makers’ websites. Check the official product pages for features available on your device and plan.
| App | A reason to try it |
|---|---|
| Fastalune | A private timer, editable history, and on-device notes |
| Zero | Fasting alongside meal and protein tracking |
| Fastic | A fasting timer with nutrition tools |
| BodyFast | A choice of structured plans and optional coaching |
| Simple | Coaching alongside food, hydration, and activity logs |
Try the same task
Start a timer, correct a timestamp if the app supports it, and see how easily you can find the record again.
Check where records live
Fastalune is a good fit when local storage and manual backups matter to you. Check each app’s privacy policy before entering personal notes.
