FastFlow vs FastFlow

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.

FastFlow turns intermittent fasting into a guided, personalized journey — and it reads your Garmin's biometrics in real time so you can actually see your fast working. Connect a compatible Garmin watch and FastFlow maps your fast through six metabolic stages — Fed, Clearing, Shifting, Burning, Cleansing, Renewing — using your live heart rate, HRV, Body Battery, and stress. Instead of a plain timer, you see what's happening inside your body, and what to do at each stage. WHY FASTFLOW - Live biometrics, not just a clock. Your Garmin data drives the ring, so every stage is grounded in what your body is actually doing. - Know what to do, hour by hour. Each stage suggests the right activities — sleep through the early hours, deep work and fasted training in Burning, rest in the long stages. - A smart end-of-fast review. Log how the fast went in two taps; FastFlow reviews it against your own baseline, entirely on your device. - Break your fast the right way. A guided, step-by-step refeeding flow with gentle food suggestions — plus a shop for break-fast staples like bone broth and electrolytes. - Build the habit. Streaks, a color-coded calendar of your fasts, and per-stage insight. LIVE ACTIVITY + DYNAMIC ISLAND Track your fast from the Lock Screen and Dynamic Island — the stage and elapsed time stay current at a glance. PRIVATE BY DESIGN FastFlow has no account. Your fasting and health data is processed on your device and stored in your own private iCloud. We don't collect, sell, or share it. REQUIRES A GARMIN Live biometric sync requires a compatible Garmin watch with the FastFlow watch app (available on the Garmin Connect IQ Store). You can also use FastFlow phone-only: start/stop fasts, follow the stage journey, log break-fasts, and keep your history.
