Lose weight with intermittent fasting — and see when your body actually switches to fat burning. Most fasting apps show you a countdown. Aayu tracks six metabolic zones in real time, from the drop in glucose through fat burning, autophagy, and renewal. Fasting stops feeling like waiting and starts feeling like progress toward your goal weight. From the moment you begin a fast, Aayu tracks your body's journey through six metabolic zones in real time — from the early transition away from glucose, through the metabolic shift, into fat burning, autophagy, and renewal. At every stage, you'll see where you are, what your body is doing, and what comes next. Fasting stops feeling like waiting and starts feeling like progress. YOUR METABOLIC DISCIPLINE SCORE Aayu distils your fasting practice into a single score built from what genuinely matters: how long you fast, how consistently you show up, how well your fasts align with your natural overnight rhythm, how often you reach the deeper zones, and the momentum of your streak. PLANS THAT MEET YOU WHERE YOU ARE Start gently with 12:12 and progress to 14:10, 16:8, or 18:6 — free, forever, with no hidden limits. Aayu builds your starting plan around your profile, activity, and last-meal time, and includes safety guardrails: gentler plans are recommended for younger users and those at lower body weights. BREAK YOUR FAST PROPERLY How you end a fast matters as much as the fast itself. Aayu includes 30 curated break-fast meals — from steamed idli with coconut chutney to overnight oats and miso soup — each chosen for being gentle on a fasting gut, with an explanation of why it works and protein-forward options to help protect muscle. EVERYTHING ELSE YOU NEED, FREE - Real-time fasting timer with live zone tracking - Hydration tracking with one-tap quick-adds - Automatic step counting - Weight logging with trends - Personalised coaching cards for your first week and beyond - "Does it break my fast?" — a searchable reference for coffee, tea, sweeteners, supplements and more - A Learn library of clear, practical fasting articles - Smart reminders for fast start, milestones, and hydration - Cloud sync and full account deletion, anytime GO DEEPER WITH AAYU PRO When you're ready, Aayu Pro adds: - 30-day and all-time insight ranges - Smart Weight Projection based on your real fasting, weight, and activity data - Monthly PDF reports with score breakdown and next-month plan - Apple Health integration — see how fasting relates to your resting heart rate, HRV, sleep, and body composition - Advanced metrics including fat-burn estimates, deep autophagy hours, and gut rest - Advanced plans: 20:4, OMAD, 36-hour, 5:2, and 4:3 - Custom plans with weekday and weekend variation Pro is available as a monthly or annual auto-renewing subscription, managed through your App Store account. Cancel anytime. PRIVATE BY DESIGN Your health data is yours. Aayu runs on EU-based infrastructure, shows no ads, never sells your data, and lets you delete your account and data from within the app. A NOTE ON YOUR HEALTH Aayu provides general wellness information, not medical advice. Advanced metrics are estimates based on published research, not clinical measurements. Fasting isn't suitable for everyone — if you are pregnant, under 18, underweight, diabetic, or managing a medical condition, consult your doctor before fasting. Always take prescribed medication on schedule. Begin your first fast tonight — and for the first time, watch what your body does with it.
