Scan your body
A short video of you standing gives your height, limb lengths and girths. Every later measurement is sized to your frame, not an average one.

Film a set. FITNDEX reads the bar and your body frame by frame and gives back the speed, power and work of every rep. No sensor on the bar. Nothing to wear.

How it works
One phone, nothing else to buy, and your first two weeks are free. Your body is measured once, your training every time, and the rating keeps the score.
Log your training
Film a set, photograph a machine screen, record a run, or type what you did. Each one comes back as a record with its work and power.
Watch your rating grow
Every record feeds one rating across strength, capacity and endurance. Train, and you can see which part of you moved.

Invite-only beta
Your digital training log.
One log where every exercise is treated the same way, for what it is: mass moved over time. A lift, a run, a jump and a carry are all measured by the same method, and physics turns them into one rating. A single number you can compare between athletes and between disciplines, to find your best combination of strength, speed and endurance. Request access and we will email you when your invite is ready.
