iPhone
ArcFast is a simple fasting tracker built around a free, no-ads intermittent fasting timer. Start a fast in one tap, follow your fasting window, use reminders and widgets, and review your history without clutter.
KNOW YOUR BODY
ArcFast displays your current metabolic phase in real-time as you fast: Sugar Burning transitions into Fat Burning, then Ketosis and Deep Ketosis. Stay informed about what's happening inside your body during every fasting window.
SEE YOUR PROGRESS
Fasting streaks, weekly bar charts, and detailed session history help you spot patterns and celebrate consistency. Review any missed fasts and learn from your patterns over time.
BEAUTIFUL THEMES
Four carefully crafted themes — Cosmos, Midnight, Cloud, and Linen — let you personalize ArcFast to match your style. Your fasting experience should feel as good as it looks.
FLEXIBLE FASTING PLANS
Choose from popular presets including 16:8, 18:6, 20:4, 22:2, and OMAD — or create a custom fasting schedule that fits your lifestyle.
STAY ON TRACK
Daily reminders to start and end your fasts, milestone notifications, and streak nudges keep you accountable without the noise.
WIDGETS
Add ArcFast widgets to your Home Screen for quick at-a-glance fasting status without opening the app.
FOOD SCAN
Add quick calorie estimates to your fasting routine. Take a photo of your meal and ArcFast gives you a clear estimate of calories and food items, so you can understand what you eat between fasting windows. Estimates are for guidance only and are not medical or nutritional advice.

Ratings & Reviews
New in 2.1.0:
You can now scan meals to estimate calories and nutrition, save your results, and keep a clearer picture of your day alongside your fasting progress.
This update also adds Apple Health support for nutrition data, improves subscriptions and restore purchases, makes the app more reliable during upgrades, and includes many small fixes across the timer, notifications, paywall, scan flow, localization, and overall stability.
As always, ArcFast stays focused, simple, and respectful of your attention.
