We started from what UK shoppers search for, like "fitness tracker with GPS", "longest battery fitness tracker" and "fitness tracker for swimming". Then we picked from the makers' and Amazon's published specs and listings, read on 23 October 2026. We favoured products sold or fulfilled by Amazon UK.
We didn't hide the downsides. Every pick comes with one honest catch, whether that's a shorter battery, no built-in GPS named on the listing, fewer exercise modes or no screen.
Check these before you buy:
GPS: do you want to track runs and rides without carrying your phone?
Battery: how often are you happy to charge, every week or every few weeks?
Swimming: look for 5ATM or 50m water resistance, plus a swimming mode.
Screen or no screen: do you want alerts on your wrist, or fewer distractions?
