Intermittent fasting works. Staying consistent is the hard part. Most people start IF motivated but quit within weeks. Not because fasting doesn't work - it does. They quit because tracking manually is tedious, they lose track of time, break fasts too early, or simply have no structure. Intermittent is the fasting timer that removes all of that friction. Simple timer. Smart notifications. Progress tracking. Everything you need to make IF effortless. HOW IT WORKS Choose Your Protocol Select from proven fasting schedules: 16:8, 18:6, 20:4, OMAD, 5:2, or create your own custom protocol. Set your eating window. Done. Start Your Fast One tap to start. The timer runs in the background. You get on with your day. Smart Notifications We notify you when your fast is complete and eating window opens. We remind you one hour before your eating window closes. You never lose track or accidentally break your fast early. Track Your Progress Every completed fast builds your streak. Your calendar fills up. You see consistency building. Weight trends (optional tracking) show the correlation between fasting and results. Simple Stats Average fast duration. Longest fast. Completion rate. Streak milestones. Everything you need to stay motivated and see your progress. WHAT YOU GET - Clean, elegant fasting timer for any protocol - Smart notifications at the right times - Streak tracking for accountability - Calendar view of your fasting pattern - Optional weight tracking with trend analysis - Stats on fasting consistency and duration - Unlimited protocol customization - Works completely offline WHO THIS IS FOR Anyone doing intermittent fasting who wants a simple, reliable timer. People who've tried IF before but couldn't stay consistent. Anyone looking for structure and accountability around their fasting practice. Both beginners learning IF and experienced fasters who need better tracking. WHY CONSISTENCY MATTERS Intermittent fasting works through metabolic adaptation. Your body needs consistent fasting windows to shift into fat burning, increase autophagy, improve insulin sensitivity, and deliver the benefits you're looking for. Random fasting - a 16-hour fast one day, eating all day the next, then an 18-hour fast a few days later - doesn't create adaptation. Consistency does. A timer gives you that consistency. You know when to eat. You know when to stop. You build the discipline that creates results. RESULTS TIMELINE Weeks 1-2: Building the habit, learning your rhythm Weeks 3-4: Hunger patterns adjust, fasting gets easier Weeks 5-8: Weight loss becomes consistent, energy improves Weeks 9+: Fasting is effortless, results are clear The key is making it through those first 3-4 weeks. That's where a timer makes the difference. Structure removes decision fatigue. Notifications prevent mistakes. Streaks create accountability. NO COMPLEXITY This isn't a meal planner. This isn't a calorie counter. This is a fasting timer. We do one thing and do it extremely well: help you fast consistently. Start your fast. Get notified when done. Track your progress. That's it. Simple. Clean. Effective. SUBSCRIPTION All features accessed through subscription. 3-day free trial included. Weekly ($4.99), monthly ($6.99), or annual ($49.99). Auto-renews unless turned off 24 hours before period ends. Manage in Account Settings.
