You've tried intermittent fasting. Not because you gave up — you forgot to start the timer. Fastivo fixes the system, not the willpower. Set your fasting window once, get notified when it opens and closes, and watch your streak build. No calorie counting, no food restrictions. Just structure. 【What Changes When You Start Fasting】 • Weight drops naturally as your eating window shrinks • Mental clarity and metabolism improve during fasting • You build a lasting habit with streaks and progress stats • AI coaching after every fast tells you what's working (Premium) 【Built for Your Daily Life】 - 5 protocols: 16:8, 18:6, 20:4, OMAD (23:1), or custom - Background timer — works accurately even when your phone is locked - Monthly calendar view to see your fasting history at a glance - Weight and wellness logging - Smart notifications: 30-minute warning + completion alert People say things like: "I lost 12 lbs in 8 weeks just by changing when I eat. No diet." "I've tried every fasting app. This one actually keeps tracking when my phone is locked." "The streak was the only motivation I needed. 90 days and still going." "16:8? 18:6? OMAD? I have no idea where to start." — Start with 16:8: 16 hours fasting, 8-hour eating window. It's the most-used protocol because it fits into a normal day — stop eating at 8pm, skip breakfast, eat from noon. Once it feels natural, you can extend it or switch to custom. The only decision you need to make today is the first one. "I've failed at fasting before — I just don't have the willpower." — Fasting doesn't fail because of willpower. It fails because the timer doesn't work in the background, notifications miss, or one forgotten session collapses the streak. Fastivo fixes the mechanics so willpower doesn't have to carry everything. "I paid for a premium fasting app and still got flooded with ads." — Fastivo Premium is ad-free. No fine print, no residual ads after you've paid. "The first few days feel rough." — They usually do. Most users say hunger waves pass in 15 minutes, and by week two you stop noticing them. "When my eating window opens, I'm afraid I'll overeat." — It happens, especially at first. That's okay. The habit is what you're building, not perfection. Tap the timer. The rest follows. "Do I have to pay upfront?" — Nope. No sneaky free trials that auto-charge. Price is shown before you commit. Cancel anytime from Apple ID settings. 【Premium Plan】 - Monthly: $4.99/month - Annual: $34.99/year (save 42%) Subscription automatically renews unless canceled at least 24 hours before the end of the current period. Payment will be charged to your Apple ID account at confirmation of purchase.
