Frequently Asked Questions
The Fort charging case has a built-in accelerometer, gyroscope, and magnet. Snap it onto any piece of equipment — like a leg press or cable stack — and it works as an external motion sensor paired with your Fort wristband, giving you the same automatic rep and set tracking for lower-body movements.
Fort is the first wearable built to automatically track strength training. It detects reps, sets, and rest periods 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 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 and Android.
