FastFlow is a lightweight fasting tracker and fasting timer for intermittent fasting plans like 16:8, 18:6, 20:4, and OMAD. It helps you start more easily, stay consistent, and better understand your own rhythm over time. With FastFlow, you can: - choose a common fasting plan or create your own custom schedule - start a fast in one tap and clearly track your duration and goal progress - receive start reminders, phase reminders, and goal reminders - keep a complete fasting history with add, edit, and delete support - review stats and weekly reports, including completions, streaks, and time trends - log weight alongside your fasting rhythm for longer-term reflection - generate share cards for completed fasts and weekly reports FastFlow is not a calorie-counting platform or a heavy social app. It is a calmer, lighter, and more reliable companion for building a fasting rhythm you can actually keep. Important: intermittent fasting is not suitable for everyone. If you are pregnant, breastfeeding, or have a medical condition or blood sugar concern, please consult a qualified healthcare professional first.
