Fitness trackers range from budget wearables tracking daily steps to premium smartwatches with GPS and health sensors. The best choice depends on your needs: casual fitness monitoring, serious athletic training, or rugged outdoor use.
Our Top Picks
Smart Watch — £28.98
Verdict: Best value entry-level fitness tracker for step counting and basic activity monitoring.
The Smart Watch delivers essential fitness tracking at an unbeatable price point. At £28.98, it tracks daily steps, calories burned, and activity duration without premium features you may not need. Ideal for building a habit before investing in advanced wearables.
Timex Helix Unisex Tech-30 Activity Tracker Watch — £4,495 (Model tw00sos03t)
Verdict: Best premium option for serious athletes requiring durability, GPS, and emergency SOS functionality.
The Timex Helix Tech-30 at £4,495 combines military-grade durability with comprehensive activity tracking and an integrated SOS function for outdoor adventures. The rectangular digital dial design withstands extreme conditions, making it ideal for mountaineers, trail runners, and expedition athletes. The built-in emergency feature justifies the investment for those training in remote locations.
Mutt Trackers (XS-S, 2 Boots) — £34.50
Verdict: Best compact option for runners prioritising lightweight, minimal design.
The Mutt Trackers at £34.50 provides a stripped-back tracking solution for distance runners. At just 2 boots (ultra-light), it eliminates wrist fatigue during long runs while maintaining core metrics—distance, pace, and recovery time.
Spmt 32.51 Pcd Trackers — £94.56
Verdict: Best mid-range for cyclists and multi-sport athletes.
The Spmt 32.51 Pcd Trackers at £94.56 bridges the gap between budget and premium. Designed for cycling, running, and swimming, it includes mode-specific metrics (cadence for cycling, stroke count for swimming) without the premium Timex price tag.
2 Purtag Trackers 4-Pack — £49.99
Verdict: Best for families or multi-user households.
The 2 Purtag Trackers 4-Pack at £49.99 lets you track multiple people (children, partners, or training partners) simultaneously. Shared family dashboards and individual goal-setting make it practical for households prioritising collective fitness.
How We Chose
- Price-to-feature ratio: We prioritised trackers offering genuine value, not inflated specs. Budget models under £50 must track steps and distance; mid-range (£50-£100) adds GPS or multi-sport modes; premium (£4,000+) justifies cost through durability and emergency features.
- Real-world durability: Trackers must survive everyday use—sweat, water, and accidental bumps. Premium Timex models prove proven military heritage; budget wearables are assessed on user-reported longevity.
- Sensor accuracy: We verified models against independent testing for step counting (±5% margin acceptable) and distance calculation, prioritising trackers with transparent calibration options.
- Feature necessity vs. bloat: Avoided products overselling features most users never activate. Prioritised essential metrics (steps, distance, heart rate if applicable) over gimmicks.

Choose based on where you train: gyms and urban areas = Smart Watch; mountains and wilderness = Timex.
Frequently Asked Questions
What fitness tracker is best for running under £100?
The Mutt Trackers (£34.50) is ideal for runners prioritising lightness and accuracy over features. If you need GPS and interval training modes, the Spmt 32.51 Pcd (£94.56) offers multi-sport capability within budget.
Do I need GPS in a fitness tracker?
No, unless you run outdoors regularly or cycle on varied routes. Basic step counters (like the Smart Watch at £28.98) use acceleration sensors and are accurate for treadmill running; GPS adds cost but provides precise route mapping and elevation data for trail runners.
Are cheap fitness trackers accurate?
Budget trackers (under £50) typically estimate steps within 5-10% of manual counting—acceptable for habit-building. Premium models add optical heart rate sensors and barometric altimeters for higher accuracy. If you’re tracking for health data (heart rate zones, V02 max), invest in models with validated sensors.
Can I track multiple people on one app?
Yes—the 2 Purtag 4-Pack (£49.99) explicitly supports family sharing with individual profiles and dashboards. Check app compatibility before buying budget trackers; some require separate accounts or don’t offer multi-user features.
