The first wearable built to track your strength. Automatically.
Reps, sets, effort, and progress.
All in one device built for longevity.
Fort gives you the feedback strength training has never had. Your sessions, fully decoded. No manual logging required.
Fort's at-a-glance metric for how intense and productive your training session was. Calculated from your exercises, sets, reps, velocity, rest times, heart rate, and training goals.
See whether each muscle group got maintenance, growth, or overload — every session.
See how hard you pushed on every set. Fort analyzes changes in your velocity and movement patterns to learn how you move as you fatigue.
Time under tension, rest times, and rep cadence tracked automatically — so you can structure your training to match your goals.
See if you're building strength, maintaining, or plateauing — week over week.
From barbell compounds to cable accessories. Fort knows what you're doing before you tell it.
Velocity, range of motion, and effort extracted from every rep. Automatically.
Slip it on. Lift. Fort handles the rest.
Movement kinematics and heart rate fused to model true muscular effort and proximity to failure. Per set, automatically.
Unlock a complete picture of your health.
