The Full Rankings & Reviews
Apple Watch Series 10
If you own an iPhone, Apple Watch Series 10 is unbeatable. The new wider display is significantly easier to read, sleep apnea detection actually works (it caught one in our testing), and the 18-hour battery finally has ‘low power’ modes that extend it to 36 hours. The S10 chip handles everything Apple Intelligence offers on watch — much smarter Siri, real-time translation, and proactive health insights.
✓ Pros
- Best app ecosystem on any watch
- Genuine sleep apnea detection
- Apple Intelligence integration
- Cellular option for run-without-phone
✗ Cons
- iPhone-only — useless for Android users
- Daily charging required
- Expensive flagship price
Samsung Galaxy Watch 7
Samsung’s Galaxy Watch 7 is the Android equivalent — sleek design, gorgeous AMOLED display, and the BioActive sensor that does ECG, blood pressure (region dependent), and body composition. Wear OS 5 is finally polished. Battery life is better than Apple Watch — 50 hours with always-on display.
✓ Pros
- 50-hour battery life
- Body composition analysis
- Wear OS 5 fluid + app-rich
- Premium design
✗ Cons
- Best with Samsung phones — limited features on other Androids
- No iPhone support
Garmin Fenix 8
Garmin’s Fenix 8 is the smartwatch for runners, triathletes, hikers, and outdoor athletes. Two-week battery life, dual-band GPS that locks instantly, AMOLED display option, and the deepest training metrics on the market — VO2 Max, training load, recovery time, race predictor. Built like a tank with sapphire crystal and 100m water resistance.
✓ Pros
- Two-week battery life
- Best-in-class GPS accuracy
- Deepest sport science metrics
- Sapphire crystal — bombproof
✗ Cons
- Smart features lag Apple/Samsung
- Bulky for everyday wear
- Premium price for sport models
Google Pixel Watch 3
Google’s Pixel Watch 3 finally feels like a real Apple Watch competitor in the Android space. Fitbit health tracking is now native, the 41mm and 45mm options fit any wrist, and Gemini AI integration is genuinely smart. 24-hour battery is the only weakness — daily charging required.
✓ Pros
- Fitbit Premium included free
- Gemini AI integration
- Two size options for any wrist
- Cleanest Wear OS experience
✗ Cons
- Daily charging required
- Best with Pixel phones (loses features on Samsung)
Amazfit Active 2
Don’t want to spend £300+? The Amazfit Active 2 delivers 80% of the experience for under £130. AMOLED display, 14-day battery, GPS, heart rate, SpO2, sleep tracking. Zepp app is well-designed, app ecosystem is limited but covers basics (Spotify offline, calls). For first-time smartwatch buyers, an unbeatable starting point.
✓ Pros
- 14-day battery life
- Excellent value
- Decent AMOLED display
- Sleep + GPS + SpO2
✗ Cons
- Limited third-party app support
- No on-watch payments
- Less polished UI
Our Verdict
For iPhone users the Apple Watch Series 10 is the obvious pick. Android users should grab the Samsung Galaxy Watch 7. Runners and outdoor athletes need the Garmin Fenix 8. Budget buyers will be impressed by the Amazfit Active 2.

Does Apple Watch work with Android?
No — Apple Watch is iPhone-only. There’s no workaround. Android users should look at Samsung Galaxy Watch 7 or Google Pixel Watch 3.
How accurate is smartwatch heart rate tracking?
Within 5 bpm for steady-state cardio (running, cycling). Less accurate during weightlifting and HIIT due to wrist movement. ECG-equipped watches (Apple, Samsung, Withings) are clinically accurate for AFib detection.
Do I need cellular on my smartwatch?
Only if you want to run/cycle without your phone. Cellular adds £50-£100 to the watch price plus £5-£10/month to your phone bill. Most users don’t need it.
