FastLedger

FastLedger is a mobile app (with an optional web dashboard) that helps intermittent fasters verify and improve adherence using objective signals instead of self-reported timers. It connects to common wearables to pull sleep, heart rate, HRV, and activity, then overlays your fasting/eating windows to show which patterns actually correlate with better recovery and fewer cravings. The app focuses on “frictionless logging”: start/stop fast with one tap, photo-only meal check-ins (no calorie counting), and a weekly adherence report that flags likely “hidden breaks” (late-night snacks, alcohol, sweetened drinks) based on behavioral patterns. It’s an AI + traditional app: AI summarizes your week, highlights the 1–2 highest-impact changes, and generates realistic window suggestions that match your schedule. It avoids medical claims and stays practical: consistency, sleep, and routine.
