TRAI VisionYour phone sees every rep. And fixes your form.
Put your phone on the floor and train. TRAI counts your reps out loud, catches the mistakes that matter and tells you how to fix them, in the middle of your set.
Free in the Trainera app on web, iOS and Android.
How it works
A coach that watches every single rep.

How TRAI sees
Three steps, then just train.
33 body points followed in every frame, on the device. TRAI knows if it sees you from the front, from the side or at 45°, and only judges what it can see clearly from there.
- 01
Put the phone down
Lean it on a bottle or a dumbbell about 2 to 3 m away. For every exercise TRAI shows where the phone goes: in front, from the side or at 45°.
- 02
Hold the start position
Two seconds in the start position and TRAI calibrates to your body. It checks that you stand right before the first rep counts.
- 03
Train, it talks back
TRAI counts every rep out loud and says the one fix that matters most, the moment it sees it. The count lands in your set when you finish.
Form correction
It tells you what to fix.
One cue per rep, the most important one, spoken the moment TRAI sees it. Safety first, then the movement, then the details. These are the exact words you hear.
Squat
Push-up
Deadlift and RDL
Curl
Overhead press
Lateral raise
Lunge
Plank and wall sit
Form correction covers squats, deadlifts, push-ups, rows, presses, curls, triceps, raises, lunges, hip thrusts, pull-ups, dips, leg raises, sit-ups and planks. The camera counts the rest.
Counting
It counts everything.
Every rep, counted
Reps for strength moves, seconds for holds. Finish the set and the number is already in your log.
Range of motion
Depth on squats and lunges, full lockout at the top, a curl that goes all the way up.
Tempo
It notices a rushed descent and a bounce at the bottom, and tells you to slow down.
Left and right
Level hips and shoulders, even arms, weight centered between both feet.
Honest holds
The plank clock only runs while your position is right. Let the hips drop and it stops.
Rated reps
Each rep gets a dot: green for clean, amber for a fault. The set ends with how many were clean and your most common mistake.
Voice coaching
Eyes on the floor, ears on TRAI.
You never have to look at the screen. TRAI says every rep, every tenth second of a hold, the fix you need and a short summary at the end of the set, with recorded voices that keep working offline.

AI Tabata
The whole workout, hands free.
Start AI Tabata and the camera stays on from the first exercise to the last. For sets of reps there is no timer: TRAI counts to your target, writes the reps into the set and moves you on. When the next exercise needs another angle, it asks you to move the phone first.
Privacy
It watches. It never records.
- The video never leaves your phone.
- Pose detection runs on the device, nothing is uploaded or recorded.
- No microphone, the camera only.
- Works with the phone you have, no wearables or sensors.
For trainers
Your clients train alone. TRAI keeps an eye on them.
Build the plan in Trainera and your clients get TRAI Vision on the exercises you chose, on the web, iOS and Android. The reps it counts land in their workout log, where you see them.
TRAI Vision FAQ
TRAI Vision is the camera coach inside Trainera. You put your phone on the floor, start a set and TRAI watches through the front camera: it counts your reps or seconds out loud, spots form mistakes such as knees caving in or hips sagging, and tells you how to fix them during the set.
Put the phone down. Start the set.
