You've tried intermittent fasting. Not because you gave up β€” you forgot to start the timer. Fastivo fixes the system, not the willpower. Set your fasting window once, get a heads-up 30 minutes before your fast ends and an alert when it's done, and watch your streak build. No calorie counting, no food restrictions. Just structure. 【What Changes When You Start Fasting】 β€’ You stop relying on memory β€” the timer and alerts keep you on schedule β€’ You build a lasting habit with streaks and progress stats β€’ 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 β€” 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 "16:8? 18:6? OMAD? I have no idea where to start." β€” Start with 16:8: 16 hours fasting, 8-hour eating window. It's the most-used protocol because it fits into a normal day β€” 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 β€” I just don't have the willpower." β€” 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." β€” Fastivo Premium is ad-free. No fine print, no residual ads after you've paid. "The first few days feel rough." β€” They usually do. The built-in timer and reminders keep you on track through those first few days. "When my eating window opens, I'm afraid I'll overeat." β€” 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?" β€” No. Premium starts with a 7-day free trial. Cancel at least 24 hours before the trial ends and you are not charged. The price is always shown before you confirm, and you can cancel anytime from Apple ID settings. 【Premium Plan】 Monthly, annual, and lifetime plans are available. The current price is always shown in the app before you confirm your purchase. 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.
