First COROS Pace with AMOLED — a vivid 1.2" touchscreen in a 32g nylon-band body, making it the lightest AMOLED GPS running watch at this price.
16 more GPS hours than the Pace 3, with 19 days typical use. Best-in-class battery life for a sub-$250 AMOLED GPS running watch.
Dual-frequency L1+L5 GPS for precise tracking in cities and trails, plus built-in voice pin recording and audio lap alerts — new for the Pace line.
Unlike WHOOP, there is no mandatory membership — pay $99 once and use Fitbit Air with the free Google Health app. Google Health Premium ($9.99/month) is optional.
Continuous heart rate, SpO2, HRV, and skin temperature tracking plus background FDA-certified AFib detection, in a 12g pebble designed to be worn and forgotten.
A week between charges, with a 5-minute top-up delivering a full day of use — significantly less downtime than WHOOP's slide-on charging system.
The right pick depends on what you optimize for.
$249 vs $396 over 3 years · no required subscription.
19 days vs 7 days battery.
4 sensors · 0.5 Hz HR sampling.
12g · no required subscription.
Serious runners on a budget who want multi-band GPS accuracy, a bright AMOLED display, long battery life, and COROS's training analytics (EvoLab) without paying Garmin mid-range prices. The Pace 4's 32g weight also makes it the lightest AMOLED GPS running watch available.
Full details →Health-focused users who want passive, 24/7 biometric tracking without a screen on their wrist. Particularly strong for those drawn to WHOOP but put off by the subscription model — the Fitbit Air delivers comparable core health data for $99 outright. Works with both iOS and Android.
