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 "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?" — 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.

Fasty is the simplest way to track intermittent fasting — 16:8, 18:6, 20:4, OMAD, or custom. One tap to start. Live Activities keep your progress on the Lock Screen without opening the app. Pick a plan, tap Start, and let Fasty take care of the rest. Your fasting timer lives where you actually look: the Home Screen widget, the Lock Screen Live Activity, and the Dynamic Island, so you always know how long you have left without opening the app. WHY FASTY - Quiet by design. No streak shaming, no animated pressure, no push spam. - Local-first. Your data stays on your device. No account. No backend. No tracking. - Just enough features. A timer, proven plans, history, widgets, and Live Activities. PLANS INCLUDED - 16:8: the most popular daily window. - 18:6: a tighter eating window for experienced fasters. - 20:4: the Warrior style, one main meal. - 24h: a full-day fast for an occasional reset. WIDGETS & LIVE ACTIVITY Add the Fasty widget to your Home Screen or Lock Screen and your remaining time updates automatically. When you start a fast, a Live Activity appears in the Dynamic Island and on the Lock Screen so progress is one glance away. NOTIFICATIONS Fasty sends a single local notification when your fasting window completes. No marketing pushes, no streak nags. You can turn notifications off any time in iOS Settings. PRIVACY Fasty does not collect data. There is no sign-in. Your fasting history lives only on your device and is shared with the widget through Apple App Groups, never sent to a server. MEDICAL DISCLAIMER Fasty is a habit-tracking timer, not medical software. Fasting is not appropriate for everyone. If you are pregnant, breastfeeding, under 18, have a history of eating disorders, diabetes, any chronic condition, or are taking long-term medication, consult a qualified healthcare provider before starting any fasting regimen.
