PulseCaller

PulseCaller is a run coach for your ears. It tells you during your run whether to speed up or slow down – by heart-rate zone or by pace, in a natural AI coach voice instead of a robot voice. Just tap Start and go. The moment you leave your zone or pace corridor, you hear it right in your ear – even with the screen locked and alongside your music.
