How Hue works

01

Pair your HR monitor

Connect any Bluetooth HR monitor in seconds. Hue works with Polar H10, Wahoo TICKR, Garmin chest straps, and more.

02

Set your max heart rate

Enter your age or test your true max HR. Hue calculates your 5 zones automatically and personalizes every coaching cue.

03

Start your workout

Pick your activity — running, cycling, rowing. Hue monitors your zone live and speaks coaching cues directly in your ear.

04

Train smarter, not harder

When you're in Z3, Hue tells you to hold. When you drift into Z4 too early, Hue tells you to slow down. Real coaching, in real time.

Every workout type, handled

Zone 2 Endurance

Long, slow runs to build aerobic base. Hue keeps you in Z2 and alerts you if you drift too high.

Interval Training

Custom intervals: stay in Z4 for 3 minutes, recover in Z2 for 90 seconds. Hue tracks your target zone and time automatically.

Fartlek / Tempo

Speed play and threshold runs — Hue guides your effort by HR, not pace, so hills and heat don't throw you off.

Cycling & Cardio

Works for any cardio activity. Zone-based training applies to cycling, rowing, elliptical — Hue adapts to your sport.

Coming soon

Your heart rate doesn't lie.
