Real-time heart-rate-zone training that turns your Bluetooth strap into a live coach — so you train at the right intensity, every minute.
Most apps tell you how hard you trained after you finish. HeartVector shows you which heart-rate zone you're in right now — so you can ease off or push harder on the fly and make every session count.
Everything you need to read your effort at a glance.
Five HR zones around one clear dial.
Live BPM, smoothed and easy to read.
Adjust your effort on the fly.
Time-in-zone so you train smarter.
From strap to insight in three steps.
Connect any Bluetooth LE heart-rate monitor (Coospo, Polar, Garmin and more).
Your live BPM and current zone appear instantly, with time-in-zone tracked as you go.
See the moment you drift out of target and adjust on the fly — no guesswork.
Color-coded so you always know where you stand.
