PerfectFast vs TrackUrFast

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. Log water, weight, blood glucose, and ketones beside your fasts, and read them on the fast's own clock in the Fast Timeline, with resting heart rate, heart rate variability, body composition, and sleep from Apple Health if you connect it. 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.

TrackUrFast is a clean, focused intermittent fasting tracker for iPhone, iPad, and Apple Watch—built around one idea: your fasting data is yours, and it should stay that way. Start a fast with a single tap and let the timer do the rest. A live countdown follows you everywhere—on your Lock Screen and Dynamic Island, on your watch face, in widgets, and through Siri—so you always know exactly where you stand without opening the app. TRACK EVERY FAST • One-tap start and stop, with a precise live countdown to your goal • Lock Screen Live Activity and Dynamic Island, updated by the system • Apple Watch app with an Always-On timer and Digital Crown navigation • Watch face complications and Home Screen widgets for an at-a-glance view • Local reminders when your fasting window ends—no need to watch the clock FASTING, YOUR WAY Everyone’s schedule is different, so TrackUrFast doesn’t lock you into one method. • Built-in plans: 12:12, 14:10, 16:8, 18:6, 20:4, OMAD, 5:2, and 36-hour • Create your own custom plans with the exact fasting and eating hours you want • Switch plans whenever you like—your history stays accurate either way SEE YOUR PROGRESS A clear dashboard turns your logs into insight, all rendered on your device. • Hours fasted per day and the eating windows between fasts • An adherence view that shows how closely you stick to your chosen plan • Daily weight logging with smooth trend lines you can compare against fasting hours STAY MOTIVATED • Daily streaks that respect your time zone and handle daylight saving correctly • Achievement badges for milestones like your first fast and 7-, 30-day streaks • Gentle haptic rewards when you close a fast or unlock a badge • Share your badges and charts straight to Instagram Stories or the system share sheet WORKS EVERYWHERE, IN SYNC Begin a fast on your watch and finish it on your phone. Your active fast and full history sync seamlessly across your devices through your personal iCloud account—no separate login required. PRIVATE BY DESIGN This is where TrackUrFast is different. There are no ads, no third-party analytics, no trackers, and no account to create. Everything you log is stored in your own private iCloud database, which means even we can’t see it. All of your stats, streaks, and charts are calculated entirely on your device. Your fasting journey stays between you and your phone—nothing is collected, sold, or shared. TrackUrFast is a tracking tool, not medical advice. Check with a healthcare professional before changing your eating patterns, especially if you have a medical condition. Download TrackUrFast and start your next fast—privately.
