Time under tension, now measured.

Not all reps are created equal. Stop letting soft ones slip in. Let tensr.fitness count time under tension, and reps for you.

Your body doesn't feel reps, it feels fatigue created by seconds and pounds (or kilograms for our friends not in the US).

tensr.fitness now lets you log the mechanical work your muscles actually did. You need a Bluetooth sensor, connect it to the app, then you can record the force curve of your workouts. Your data will once and for all help you answer the question: "Did I train hard enough today?"

How it works

1. Grab a sensor. A Tindeq Progressor, a WH-C06^†, a WH-C07^†, or a WH-C100^† (all on Amazon), or even a KForce-Link — or many other BLE sensors supported soon.
2. Clip in. Add the sensor in-between your anchor and your handle using any of: straight bands, looped bands, cable machine, TRX, gym rings, etc.
3. Train. Open the tensr app in Chrome (or Edge), pair the sensor, hit start.
   No accounts, no install, completely cloud optional. Seriously.
4. See the data. Time under tension, impulse, peak force, and a session-over-session view that tells you if you actually progressed. All local. All exportable. Yours.

What tensr.fitness is for

• The data-geek home-gym lifter. You already train hard. You want a number, not a guess.
• Remote coaches and physical therapists. Band programs you prescribe, with objective evidence the work happened at the prescribed intensity.

We’re building in public. Infrequent updates — a new sensor supported, a significant feature landing, the Cooper Clinic pilot opening. Nothing else.
