About this app

Film a set. Get an answer.

Trayner watches you lift. Prop your phone up and record a set. Trayner tracks 33 points on your body through every rep, scores each one and tells you the one thing to fix first.

FORM CHECK
Measured today on seven lifts: bodyweight squat, bench press, Romanian deadlift, push-up, overhead press, dumbbell overhead press and military press. Depth, torso angle, knee bend and tempo are measured, not guessed. If Trayner can't see you well enough to score a set, it says so and tells you which angle to film from. More lifts are added once they pass validation on real clips.

LIVE COACH (PRO)
Counts your reps out loud and cues you mid-set, in your ear. Validated on squats; other lifts are in beta.

TRAIN
Open the app and today's session is already there, built from last week. New workouts start from your last session, so the weights are filled in. Hit every rep last time? Trayner suggests adding 2.5 kg.

RECOVER
Reads sleep, resting heart rate and HRV from Apple Health and compares them with your own baseline, not a population average. Short night? Keep the weight and drop a set. Tap any call to see why it was made.

EAT (PRO)
Photograph your meal and correct any ingredient before it is logged. Scan barcodes and nutrition labels. Water and post-workout protein follow what you trained.

PROGRESS
Personal records, strength rank by muscle, body composition and progress photos in one place, all feeding next week's plan.

SWITCHING?
Import your workout history from other apps, so your first session in Trayner already knows your last one. Import is free on every plan.

ON YOUR WRIST
Start a workout and it opens on your Apple Watch. Tick off sets, run the rest timer and feel a tap for every rep Live Coach counts. The Watch controls need an iPhone.

FREE AND PRO
Workout logging, routines, history, personal records, food logging and import are free, with no time limit. Pro adds Form Check, Live Coach, a weekly plan built for you, food photo analysis, the Recovery score and coach chat. Your first 14 days include Pro. No card, nothing to cancel. After that you stay on Free unless you choose to keep Pro.

Your training log is stored on your device. Trayner gives training guidance, not medical advice.
