Train first. Log after. TrainScribe is a voice-first workout diary. After your session, just say what you remember, in any order: "Circuit, 4 rounds: squats, push-ups, plank. Then rows, 8 each arm at 15 kg." TrainScribe rebuilds it into a clean, structured session: blocks, exercises, reps, weights. YOUR VOICE STAYS ON YOUR PHONE Your recap is transcribed directly on your device by a bundled speech model. The audio never leaves your phone: not to us, not to anyone. Only the text of your recap is processed to structure your session. SEE WHAT YOU TRAINED Every session maps to the muscles you worked. Watch your training mix and balance evolve over time, not just a list of entries. A gentle weekly focus suggestion helps you keep things balanced, without scores, pressure or guilt. LEARNS YOUR VOCABULARY Call an exercise whatever you like. TrainScribe learns your words once and recognizes them next time. YOUR WORKOUTS, IN APPLE HEALTH (PRO) Turn on sync and every saved session lands in Apple Health as a real workout, next to your heart rate, sleep and daily activity, readable by any compatible app you allow.
