What Emberlap is

Train in the zone

Five HR zones from blue recovery to red max. Earn Burn Points for sustained time in the orange and red zones.

Your heart rate, live

Apple Watch streams HR to your iPhone every second. No chest strap, no extra hardware — just put on your watch and go.

Hear when to push

Spoken cues guide every interval — when to pick up the pace, when to recover, when the next block starts. Eyes stay on the treadmill.
