About FastTrack Fasting Timer
FastTrack is the cleanest, most intentional way to track your intermittent fast. No clutter. No noise. Just a precise countdown that keeps you focused — glanceable from your Dynamic Island and Lock Screen without ever opening the app. Live Activities put your progress exactly where you need it. FastTrack uses iOS Live Activities to display a real-time countdown on the Dynamic Island and Lock Screen. Your fast is always visible, always accurate — even when your phone is sitting face-down on a desk. Every protocol, handled. Whether you fast 16:8, 18:6, 20:4, or push through an extended 36 or 72-hour window, FastTrack supports them all — plus fully custom durations. Set it once and let the app do the rest. Your history, beautifully organized. A calendar view gives you a complete record of every fast at a glance. Tap any day to see the full breakdown. Weekly charts, monthly trends, personal bests, and consistency tracking reveal what's actually working. Available with Pro. Streaks that hold you accountable. FastTrack tracks your fasting streak, sends a heads-up when it's at risk, and celebrates every milestone you hit. Consistency compounds — this is how you measure it. Synced with Apple Health. Fasting windows are recorded automatically, so your data lives where your other health metrics do. Smart notifications remind you when to start, alert you as the finish line approaches, and confirm every completed fast. No ads. No tracking. No fluff. FastTrack does exactly what it says and nothing it shouldn't. All your data is yours — export everything to CSV anytime. Pro unlocks advanced insights, trends, and export tools for people who want the full picture. Start your fast. FastTrack handles the rest.
