How to choose a smartwatch

Phone compatibility comes first

The single most important factor. Apple Watch only works with an iPhone. Wear OS watches (Samsung Galaxy Watch, Google Pixel Watch) are best on Android. Garmin, Fitbit and Amazfit work with both — the safest choice if you switch phones.

Battery life

Full smartwatches last 1-2 days; fitness-focused watches (Garmin, Amazfit) can run a week or more. If you hate nightly charging, prioritise battery.

Health & fitness sensors

Look for a heart-rate monitor (standard now), built-in GPS for accurate workouts, and — if you care about it — blood-oxygen (SpO2) and sleep tracking.

Display & build

AMOLED screens look best and are worth it. Check water resistance (5ATM or higher) if you swim.

Smartwatch, fitness tracker or smart ring?

Frequently asked questions

What is the best smartwatch in the UK in 2026?

It depends on your phone and budget. For iPhone users, an Apple Watch is the natural choice; for Android, Samsung Galaxy Watch and Google Pixel Watch lead, while Garmin excels for fitness and battery life. Our list ranks the most popular models by live price so you can find the best value.

Which smartwatch works with both iPhone and Android?

Garmin, Fitbit, Amazfit and most fitness-focused smartwatches pair with both iOS and Android. The Apple Watch is iPhone-only, and some Samsung/Wear OS features are best on Android. Check the compatibility filter before buying.

How much should I spend on a smartwatch?

Budget smartwatches start around £30-60 and cover the basics (notifications, step tracking, heart rate). Mid-range models (£150-300) add GPS, better displays and health sensors. Flagship watches run £350+. Most people are well served in the £100-250 range.

Do I need a smartwatch with built-in GPS?

If you run, cycle or hike and want accurate distance without carrying your phone, yes — built-in GPS matters. For general notifications, steps and heart rate, connected GPS (using your phone) is fine and cheaper.
