PerfectFast

Fasting timer and tracker

Free · Designed for iPhone. Not verified for macOS.

See your fasting story over any time period — every fast charted against its target, weight in step, completion at a glance — plus one-tap drink presets. PerfectFast helps you track intermittent and extended fasts with a calm, focused experience. Set up a fasting plan, follow your active fast, review your history, and see progress statistics without clutter. The app supports common fasting schedules, custom durations, reminders, fasting stages, history views, statistics, appearance settings, local data export, and Live Activity support on compatible devices. The Apple Watch companion lets you check your current or scheduled fast from your wrist, start or end a fast when your iPhone is nearby, and keep progress on your watch face with complications. Your fasting data stays on your device unless you choose to export or share it.

Progress, redesigned. See your fasting stats for any period — this week, this month, six months, a year, or all time — with one clean set of cards. At week and month view, every fast draws its own bar against its target, so a strong week is visible at a glance — tap any bar to revisit that fast. Real calendar weeks and months let you page back through your history and compare like with like, with "vs previous" deltas on your totals. The Completion card now shows how often you reach your goal, your average rating, and how many days you fasted. Curious which fast length works best for you? The By Length breakdown leads with your best-rated target and expands for the full picture. Your weight trend follows the same period you're viewing, so fasting and weight line up over the exact same window. Blood glucose and ketones moved to the Journal, right on the day you logged them, with full history and charts one tap away. Hydration logging is faster too: save your favorite drinks as presets and log water and electrolytes in one tap. Plus a friendlier notification setup, clearer Lock Screen widgets, and a smoother timer ring.
