Lose weight and take control of your eating with Fastly — the complete intermittent fasting tracker with no subscription. Start a fast in one tap and watch a beautiful timer reveal exactly what your body is doing right now: fat-burning, ketosis, and autophagy. Follow any schedule, track your weight and progress, build streaks, and stay motivated — with no $70/year subscription. Most fasting apps lock the features that keep you consistent behind an expensive paywall. Fastly gives you everything, with no paywall. LIVE FASTING STAGES See your body move through each stage as your fast progresses — fed, fat-burning, ketosis, autophagy, and growth hormone. Know exactly when you'll reach the next stage and what it does for your body. It's the motivation that gets you through the hard hours. A TIMER YOU CAN TRUST One-tap start and stop. A glowing ring fills as you fast and shifts color with each stage. Your elapsed time stays exact after backgrounding, a reboot, or a phone restart — because a wrong timer is the fastest way to quit. EVERY SCHEDULE INCLUDED 16:8, 18:6, 20:4, OMAD (23:1), 14:10, 12:12, 5:2, Warrior, Circadian, and fully custom. Beginner to advanced — switch anytime and set a recurring weekly plan. SEE YOUR RESULTS Log your weight and watch the trend move toward your goal. Track BMI, body measurements, fasting hours, average fast length, and completion rate with beautiful charts. STAY MOTIVATED Build streaks, take on challenges, earn milestones, and beat your longest fast. Visible progress is what keeps you going. WATER AND REMINDERS Track hydration and get calm, motivating reminders — fast start and end, eating-window open and close, "you'll reach ketosis in 1 hour," and log-your-weight nudges. LEARN AS YOU FAST Built-in guidance on fasting benefits, what breaks a fast, the science of the stages, and beginner tips — no paywall. NO SUBSCRIPTION, NO PAYWALL All fasting protocols, live stages, weight and progress tracking, streaks, challenges, water, reminders, and content are all included. No subscription, no "shell" tier. There's an optional one-time remove-ads upgrade if you'd like a clean screen.
