Frequently Asked Questions

Fort is the first wearable built to automatically track strength training. It detects every rep, set, and rest period using motion sensors, no logging. It also tracks cardio, sleep, stress, and everything else you expect from a modern wearable.
Fort uses an IMU (accelerometer + gyroscope) and a PPG heart rate sensor to recognize exercises, count reps, measure bar speed, and estimate proximity to failure — all in real time. It currently recognizes 50+ exercises, from barbell compounds to cable accessories.
For strength: session scores, per-muscle volume breakdowns, proximity to failure, time under tension, rep velocity, rest times, and rep cadence. Beyond strength: heart rate zones, VO2 max estimation, sleep stages (deep, light, REM), recovery scoring, overnight HRV, all-day activity, and real-time stress detection.
Yes! It's meant as a general-purpose tracker that is superior at tracking strength and putting strength in context of your overall health.
Fort weighs under 30g, has a 7-day battery life, and connects via Bluetooth Low Energy. It comes with interchangeable bands to match your style. The companion app is available on iOS.
7 days with normal use.
