Hone vs FastingWindow

Hone is the intermittent fasting app for the disciplined — one tap, Dynamic Island Live Activity, Apple Watch complications, and Precision Window guardrails. Free core. No account. No ads. No tracking. Your fast stays yours. If you've outgrown "wellness" apps that chase you for $70/year to show a timer — Hone is built for you. WHAT HONE DOES DIFFERENTLY Most fasting apps overwhelm you with features you'll never use — calorie tracking, food diaries, social feeds, coaching chatbots. Hone does one thing at a precise level: tracks your fast and shows you the biology of what's happening inside you, in real time. → Start a fast in under 2 seconds → See your timer live on Dynamic Island without opening the app → Check your fast from your wrist with the Apple Watch complication → Watch your body shift through metabolic zones as it happens → Track your history, streaks, and personal records PRECISION WINDOW ENGINE (Hone Pro) Most fasting apps let you cheat. Hone doesn't. The Precision Window engine enforces the guardrails that make fasting actually work: • Caffeine cutoff — warns you when late caffeine will wreck tomorrow's sleep-protected fast • Training-day exception — your long-run day isn't your OMAD day • Sleep protection — the app refuses to auto-end a fast while you're sleeping • Max-fast cap — hard stop at the duration you set, because extended fasts without supervision are a bad idea FAST PURITY — CLEAN vs BLUNTED Not all fasts are equal. Coffee with cream is not a clean fast. Hone lets you toggle Clean or Blunted, and your streak, complication, and Dynamic Island color reflect the truth. FOCUS FILTER Turn on Fasting Focus and DoorDash, UberEats, Postmates notifications disappear until you break your fast. Precision isn't just physiology — it's removing the trigger vectors. METABOLIC ZONES — KNOW WHAT YOUR BODY IS DOING As you fast, your body moves through distinct physiological phases. Hone tracks them in real time: • Fed — Digestion active, insulin managing glucose storage • Early Fasting — Insulin drops, glycogen stores deplete • Fat Burning — Metabolic switch flips, fat becomes primary fuel • Ketosis — Ketone production increases, mental clarity sharpens • Deep Ketosis — Autophagy begins, cellular cleanup underway Each zone transition triggers a notification so you know exactly when your body shifts gears. BUILT FOR YOUR LOCK SCREEN Your fasting timer lives on Dynamic Island and your Lock Screen. No need to unlock, no need to open the app. Glance and know. Home Screen and Lock Screen widgets keep your fast visible throughout the day.

FastingWindow is the cleanest, simplest way to track intermittent fasting — no account, no subscription, no noise. Pick a schedule (16:8 or 12:12), tap Start Fast, and watch your progress in real time. A live ring shows exactly where you are in your fast, and as the hours pass you'll move through five metabolic stages — from initial digestion all the way to deep ketosis. Each stage is explained so you actually understand what your body is doing, not just how long you've been waiting.
