Fastly Fasting Tracker vs Climb

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: a heads-up an hour before each new fasting stage, a cue when your fast is complete and your eating window opens, and one before it closes. 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. Whether you're starting your first 16:8 or chasing autophagy on OMAD, Fastly gives you the complete toolkit to lose weight, burn fat, and feel great through intermittent fasting. Download Fastly and start your first fast today — no subscription needed. Fastly is not a medical device and does not provide medical advice. Talk to your doctor before starting any fasting or weight-loss program.

Climb is an intermittent fasting tracker for iPhone and Apple Watch. IT CAN'T LOSE YOUR FAST Most fasting apps store how long you've been going and count upwards. That is why they lose fasts after a restart, a reboot, or a daylight-saving change — the most common complaint in the category. Climb never stores elapsed time. It records the instant you started and works everything out from the current time whenever you look. There is no running total to drift, so there is nothing to lose. Change timezone mid-fast and the number stays right. A LADDER, NOT A RING Seven stages, marked by how long you have been fasting, with the colour moving amber to green to blue as you climb. The timings are typical ones drawn from research on averages — not measurements of you. WHERE YOU ALREADY LOOK • A Live Activity on the Lock Screen and in the Dynamic Island • Home Screen widgets • An Apple Watch app, and complications for four watch face families All of them keep counting while the app is closed. EDIT ANYTHING • Start a fast late and move the start time back • Log one you forgot to record • Extend a goal mid-fast • End one by mistake and undo it • Export your whole history, and import it back NOTHING LEAVES YOUR PHONE No account. No sign-in. No analytics. No advertising identifiers. No third-party SDKs. Climb makes no network requests at all — there is no server for your data to reach even in principle. Your fasts live on your device and nowhere else. Climb is a tracker, not medical advice. Talk to a doctor before changing how you eat — particularly if you are pregnant, breastfeeding, diabetic, taking medication, or have a history of disordered eating.
