FastFlow is a fasting tracker that goes beyond the timer. AI coaching responds to your actual fasting history. iOS home and lock screen widgets keep your fast visible without opening the app. HealthKit syncs steps, energy, and heart rate into your progress. Streak shields protect your consistency. A community forum keeps you motivated. Built solo in Flutter. Every feature exists because I needed it myself.

Hey Product Hunt, maker here. I built FastFlow because every fasting app I tried was just a countdown timer. Nothing that actually understood my data or told me something useful. The two things I am most proud of: the AI coaching layer uses your real fasting history before every response so the advice actually adapts over time, and the iOS home and lock screen widgets were genuinely hard to build since they run in Swift not Dart inside a Flutter app. A few things I would love honest feedback on: Does the onboarding explain the fasting windows clearly enough for beginners? Is the AI coaching actually useful or does it feel generic? What feature would make you open the app every single day? Download is free, no paywall to try the core features. Ask me anything.
