Voice-powered workout tracking

Just say it.
Build logs it.

Build is the workout tracker that listens. Call out your reps mid-set and they're logged before you rack the bar — no typing, no tapping. And you can import any routine straight from a screenshot.

Free to start. Built for iPhone & Apple Watch.

Voice logging

Log a set without touching your phone.

Tap the mic, say "185 for 8", and Build writes it to the right exercise instantly. Your hands stay on the bar and your head stays in the set.

  • ✓ Understands natural speech — weight, reps, even RPE
  • ✓ Log straight from your Apple Watch, hands-free
  • ✓ A confirmation you can tap once to correct — then back to lifting
