Science-backed, engineered human optimization
Your personal recovery expert powered by on-device AI. Get daily protocols tailored to your sleep, training load, and recovery metrics.

Every morning, Flow analyses your sleep, energy, and recovery data to deliver one clear verdict: rest, recover, or train hard. Not a dashboard to interpret. Not a chart to decode. A decision backed by over 100 data points processed entirely on your device. No cloud. No third parties. No monthly fee.

It's not just about hours. It's about quality, efficiency, and waking up ready to perform. Flow turns sleep from guesswork into precision.

Training load, vitals, and workout intensity tracking that tells you when to push hard and when to back off. No guessing. No overtraining.

VO2 Max, HRV, and resting heart rate tell you whether your body is building fitness or breaking down. Flow watches the signals before they become problems.
Recovery protocols generated on your phone from your Apple Health data. No cloud, no subscription, built for endurance athletes who want a clear answer, not another dashboard.
