How it works
A transparent, spec-based way to pick a fitness watch: no guesswork, no commission-weighted nudges.
Tell us how you train, which phone you carry, your wrist size, the features you actually use, and your budget. No email required.
Your answers run through a fixed scoring formula that compares them with the published specs of 67 watches from 17 brands, including Apple, Garmin, Polar, Coros, Suunto, Samsung, Google and Fitbit.
You see why each watch matched, where it falls short, who should skip it, and links to compare specs side by side. The same answers always produce the same ranking.
Scoring inputs
Nine criteria with fixed weights. Every result shows the points each one earned, and the methodology page explains exactly how each fit is calculated.
Is the watch built for the sport or activity you chose?
Does it pair fully with your iPhone or Android phone?
Smartwatch, sport watch, band or hybrid: the shape you asked for.
GPS, ECG, SpO₂, maps, music, payments, LTE, swim-proofing: the ones you ticked.
The manufacturer's rated battery life against the days you want between charges.
Minimal, rugged, luxury or sporty.
A small nudge towards the brands you like.
Case size against your wrist circumference.
List price against your budget, plus a hard ceiling so a $700 watch never shows up for a $200 budget.
Read the full formula on the methodology page, including what the score cannot tell you.
