FAQ

How does Fort track leg exercises?

The Fort charging case contains an accelerometer, gyroscope, and magnet. By snapping it onto gym equipment like a leg press or cable machine, it functions as an external motion sensor. This sensor pairs with your Fort wristband, enabling automatic rep and set tracking for lower-body movements.

What is Fort?

Fort is the first wearable device specifically built to automatically track strength training. It uses advanced motion sensors to detect exercises, count reps, and measure rest periods, eliminating the need for manual logging. It also tracks other essential health metrics like cardio, sleep, and stress.

How does automatic tracking work?

Fort utilizes an Inertial Measurement Unit (IMU) comprising an accelerometer and gyroscope, along with a PPG heart rate sensor. This combination allows it to recognize exercises, count repetitions, measure bar speed, and estimate proximity to failure in real-time. It currently supports over 50 exercises.

What metrics does Fort track?

For strength training, Fort tracks session scores, per-muscle volume, proximity to failure, time under tension, rep velocity, rest times, and rep cadence. For general health, it monitors heart rate zones, VO2 max estimation, sleep stages, recovery scores, overnight HRV, all-day activity, and real-time stress.

When does Fort ship and what is the cost?

Fort is available for pre-order at $289, which includes the device and a one-year app subscription (normally $79.99/yr). Batch 1 is scheduled to ship in Q3 2026.
