Fastiya : Fasting Timer+Macro

Live body-state tracking (fat-burn, ketosis, autophagy), AI coaching from your real data, macros & wearable sync. Free 7-day trial.

Track every hour of your fast and get AI coaching built on your real data — not generic tips. Try Fastiya Pro free for 7 days.

YOUR BODY, HOUR BY HOUR Watch your body shift from fat-burning to ketosis to autophagy in real time. Milestone alerts tell you exactly what's happening at 8h, 12h, 16h, and beyond — backed by science, not guesswork.

AN AI COACH THAT ACTUALLY KNOWS YOU Ask questions and get answers built on your real fasting history, sleep, recovery, and stress data — not one-size-fits-all advice. Wake up to a Morning Report summarizing your sleep, recovery, and readiness before you even open the app.

MACROS & NUTRITION, SIMPLIFIED Log meals and see your day at a glance: calories plus protein, carbs, and fat. Get smart feedback on your goals, hydration, and diet — no spreadsheets required.

SLEEP, FASTING & STRESS, CONNECTED Journal Insights surfaces the correlations that matter — how your sleep affects your fasting, how stress shows up in your recovery — so you know what's actually moving your progress.

SYNC YOUR WEARABLES Connect Fitbit, Oura Ring, or WHOOP for deeper recovery and readiness data layered directly into your coaching.

KNOW YOUR BIOLOGICAL AGE See how your habits are shaping your biological aging clock, not just the calendar.

STAY ON TRACK Streaks, achievements, and smart notifications keep you motivated without the noise — context-aware nudges, not constant pings.

ON YOUR WRIST A dedicated Apple Watch app keeps your fast, streak, and body state visible without reaching for your phone.

Try Fastiya Pro free for 7 days — full access to AI coaching, wearable sync, bio age, and advanced analytics. Cancel anytime.
