Voice coach for Garmin
Your race
engineer.
Your watch keeps an eye on the numbers. Your phone speaks in your headphones. One press on Lap and you get an answer, without looking down.

01 — How it works
The watch triggers. The phone speaks.
- 01
Watch
A full-screen data field on your Garmin follows pace, heart rate and cadence, and notices when you drift from the plan.
- 02
Phone
The app turns that moment into a short, spoken instruction and plays it over your music.
- 03
Lap
Press Lap to ask. You get the split you just ran, read out loud, and your activity records as usual.
02 — One run, three moments
Hear what it sounds like.
Two sentences. One number each. Then silence.
« Rep 4, 400 metres at 3 minutes 50. Average heart rate 171. »
« Pace at 4 minutes 46, faster than planned. Ease off to 5 minutes 30. »
03 — Principles
Built to stay out of the way.
The mic is never on
A threshold or a press on Lap triggers the coach. Never your voice.
Native recording
Multi-band GPS, profiles, auto-lap and the FIT file stay exactly as Garmin made them.
Works offline
No signal for three seconds and the phone answers on its own, from the watch numbers.
Never a diagnosis
Recovery is compared to your own baseline. Nothing about health is phrased as a verdict.
04 — After the run
Meet Miles.
Back home, Miles reads your session, your plan and your recovery, and talks it through with you. The engineer speaks while you run; Miles speaks after.
