Deepinder Goyal says Temple’s wearable posted a 1.18 bpm mean absolute error, against 1.94 for Apple Watch Series 12 and 3.14 for WHOOP MG, but those figures are his company’s own account and the study’s independence and methodology aren’t established. Until an independent lab runs the same test, treat the ranking as a marketing claim and check whether Temple publishes its protocol before you buy.
Marty’s Take:
Heart rate error of 1.18 bpm sounds decisive until you ask what the reference was: a chest strap, an ECG, and during which activity. Wrist optical sensors diverge most during intervals, not steady runs, so a single mean hides the part you care about. Until someone else repeats the test, pick between the Apple Watch Series 12 and WHOOP MG with our best fitness tracker picks, not a founder’s tweet.
