How ArcFast compares
| Instead of… | You get with ArcFast |
|---|---|
| A generic clock timer | Fasting-aware timing with phase labels, plans, and a saved history — not just a countdown you have to remember to set. |
| A spreadsheet or notes app | Automatic logging with streaks and optional meal scanning, instead of typing every fast and meal by hand. |
| A bloated fasting app | No ads, no forced account, and no cluttered dashboard — just the timer and your history. See the no-ads fasting app page. |
Privacy and simplicity
ArcFast keeps your fasts, streaks, and meals on your iPhone. No account, no ads, and no analytics — the app is private by design.
ArcFast is a tracking tool, not medical advice. Talk to a healthcare professional before starting or changing a fasting routine, especially if you are pregnant, diabetic, under 18, managing an eating disorder, or under medical supervision.
