What It Does

๐ŸŽ™๏ธ

Voice Moments

Record on your Watch or iPhone between sets. Say what you did and move on โ€” AI takes care of the rest.

๐Ÿค–

AI Workout Logs

Your voice gets transcribed and processed by AI into a structured workout log โ€” exercises, sets, reps, weights. Edit anything it gets wrong.

โค๏ธ

Live Health Data

Heart rate and calories tracked live during your session. Saves to Apple Health as a strength training workout.

๐Ÿ“Š

Insights

See trends across workouts โ€” volume, frequency, muscle groups. Weekly stats and a story viewer to swipe through.

๐Ÿ“ฑ

Social Content

AI writes Instagram captions, tweet threads, and reel scripts from your session. Post-worthy without the effort.

โš™๏ธ

Works Offline

No signal at the gym? Recording still works. AI processing queues up and runs when you're back online.

How It Works

1

Start a workout on your Watch. Between sets, tap record and say what you did โ€” "bench press, 4 sets of 8 at 185."

2

Audio transfers to your iPhone and gets sent to OpenAI's Whisper for fast, accurate transcription.

3

End your workout and AI puts it all together โ€” a structured log, training insights, and ready-to-post social content.
