The Challenge
Every fitness app on the market makes you stop mid-set to tap through a screen: log a rep, start a rest timer, check what's next. That's a real problem in the middle of a strength workout, when your hands are on a bar or full of chalk and your phone is the last thing you want to touch.
Nobody had built a fitness app that worked the way a real trainer does: talking you through the set without asking you to look at anything.
The Solution
New York App Devs built Training Mate as a voice-first coaching app that runs with the phone locked in your pocket. The AI coach talks you through every set and rest period out loud, using background audio so you never have to look at a screen mid-workout.
After each set, the coach asks how many more reps you had left, then adjusts next session's weight and reps automatically.
What We Built
The practical product capabilities built into Training Mate.
the AI coach talks you through every set and rest period out loud, phone locked in your pocket.
background audio keeps coaching running while the app is minimized, so you never touch the screen mid-set.
say "more time" or "how much time left" during rest, no tapping required.
post-set difficulty check-ins feed directly into next session's weight and rep recommendations.
the coach calls out real progress out loud, like going from 10 reps to 12 the following week.
the trainer updates exercise instructions and coaching scripts directly, with version control, no engineering needed.
an abstraction layer lets the team benchmark voice AI providers on cost and quality without a rewrite.
