Strength · Capacity · Endurance
Every athlete.Every exercise.One rating.
A heavy single, a 20 minute AMRAP and a half marathon have never shared a scoreboard. FITNDEX measures what each one produced, from the phone in your pocket, and scores them on one rating. For athletes who still compete, and for the ones who still train like it.

Required
Optional
One lens
Three ways of seeing the same thing.
Lifters watch bar speed and runners track pace. Researchers model power. The best athletes in the world train by feel and call it RPE. Each one is a piece of the same physics. FITNDEX is the first to read all three, together, from one phone.
Velocity.
What the market tracks
Velocity on every rep, every run. Recorded straight off your phone. No special equipment.
Power.
What the lab models
Work and power for every rep, every set and every run, on the same models the research uses.
Effort.
What the best athletes train by
Tell it how hard the set was. That one number unlocks everything the camera could not see.
Three signals that never talked to each other. FITNDEX reads them as one.
Long forearms. Take a slightly closer grip on presses and pulls.
Long shins. Knees travel forward, so the bottom of your squat stays upright.
Your frame
Measured on your body, not an average one.
Enter your height and weight, then give the camera a minute and six positions. From then on every number is worked out for the frame you actually have: long shins, long forearms, whatever you were built with. A pushup at your size counts as your pushup, not a textbook one, so bodyweight work finally shows up in the record with a number on it.

What it takes
The instrument is already in your pocket.
Film a set and every rep comes back with speed, work and power, so five reps at the same weight show up as five different efforts. Start GPS and a run is measured the same way. No bar sensor, no chest strap, no watch. Just the phone, every session.

The rating
Seven seconds. Three minutes. Everything after.
Strength is what you can produce in the first seven seconds. Capacity is what you get done before your breathing takes over. Endurance is what you can hold after that. A lifter lives in the first window, a runner in the third, and most of us train across all three. Each window is scored on its own. Together, they are your rating.

Invite-only beta
Numbers you can trust.
Nothing reaches you until it has passed our testing. We would rather you wait a little than ever doubt a number. We are a small team building carefully, so the doors open in waves as each milestone is met. Request access and your invite will follow when your wave opens.
Figures on this page are examples. FITNDEX is in an invite-only beta, and some exercises are still being validated.
