The simple fasting tracker for people who just want to fast — not navigate a bloated wellness platform. No account. No ads. No data collection. Free forever, with optional Premium for power users. Whether you're running 16:8, 18:6, 20:4, 14:10, OMAD, or a custom schedule, Steadfast tracks your fasting windows with a clean, focused interface that stays out of your way. EVERYTHING YOU NEED — FREE One-Tap Fasting Timer Start, pause, and complete fasts with a single tap. Choose from 9 presets (12:12 through 48-hour fasts) or dial in any custom duration. Water Tracking Built In Log water right from the Timer screen. Set your bottle size, pick a daily goal, and tap to log. Your hydration counts toward both your wellness goal AND Apple Health. Fasting Zones See what's happening in your body as you fast — from Fed State through Early Fasting, Fat Burning, Ketosis, and Autophagy. Evidence-based zone timings keep you informed and motivated. Fasting Streaks Stay motivated with streak tracking that rewards consistency. See your current streak and longest streak at a glance. Hydration Reminders Gentle nudges during active fasts to keep you drinking. Fully configurable — and never intrusive. Home Screen Widgets Fasting Timer, Fasting Heatmap, Hydration Heatmap, Combined Dashboard, and Water Quick-Add. All widgets match your app theme automatically. Apple Watch App Separate Fasting and Water tabs. Start fasts, log water, check your progress — all from your wrist. HealthKit Integration Water intake writes to Apple Health as dietary water. Weight syncs both ways. Your data stays yours. iCloud Sync Your fasts, water log, and streaks sync across all your devices. Fasting History and Calendar Review completed fasts with monthly stats — hours fasted, daily averages, and consistency tracking. PREMIUM — FOR THE EXTRA MILE Everything you need is already free. Premium unlocks: - Advanced Analytics — Heatmaps, week-over-week trends, and time-in-zones breakdowns - Custom Themes — Beach, Midnight, Slate, and more - CSV Export — Take your data wherever you need it - Extended Widget Library — Full widget gallery unlocked - Priority Support $3.99/month or $24.99/year — a fraction of what other fasting apps charge. WHY STEADFAST? Most fasting apps have expanded into calorie counters, meal loggers, AI coaches, and social networks — then locked basic features behind $70-80/year subscriptions. Steadfast does one thing well: help you fast consistently and stay hydrated. No bloat. No bait-and-switch. No account required. Just open the app and start. Built by ManifestLab.
