Trn.ai: Gym Workout Planner

Tell your coach what you feel like today. It writes the session, counts every set and remembers the numbers you hit six weeks ago.

TRN.AI is a strength coach you talk to.

There are no plan builders to fill in and no dropdowns to hunt through. You write what you want — "legs today, my knee is cranky", "same as Monday but heavier" — and the coach writes the session, sets the targets, and gets out of your way.

CHAT IS THE APP Ask for a workout and it appears. Ask how your bench is going and you get the number, not a lecture. Say "swap the leg press, the machine is taken" and the coach picks the alternative — you never scroll a list of 400 exercises.

BUILT FOR THE GYM FLOOR The workout screen is one thumb wide. Warm-up ramp, target reps and rest are laid out before you reach the rack. Logging a set is one tap. Change your mind mid-set and tap the number to edit it.

IT REMEMBERS Every session is kept — the weight, the reps, the day. Progress charts are drawn from what you actually lifted, and personal records are noticed and kept without you marking anything.

APPLE HEALTH Finished workouts go to Apple Health with their start time, duration and an active-energy estimate. One way, device to Health — your training data is never sent anywhere else for it.

SEVEN LANGUAGES, PROPERLY The coach answers in your language, and the app is translated to match: English, Español, Deutsch, Français, Русский and more. Not machine-swapped labels — written translations, including the plurals.

TALK TO A PERSON Something looks wrong, or a question about your plan? Support is a real conversation inside the app, answered by a human.

FREE AND PREMIUM The free tier gives you a daily allowance of coach messages — enough to train on. Premium raises that allowance substantially, for people who talk to their coach between sessions as well as during them.

Requires an account. Workout data syncs to your trn.ai account so it survives a new phone.
