A fitness tracker is one of the most genuinely useful tools a dad can buy for his health. Not because it magically makes you fitter, but because it makes you aware — of how much you’re actually moving, how well you’re actually sleeping, and whether your body is recovering or running on empty.
Here’s an honest comparison of the three most popular options for dads in the UK.
What to Look For in a Fitness Tracker
- Sleep tracking — for dads, sleep quality data is often more useful than step counts
- Heart rate monitoring — continuous HR tracking enables meaningful recovery and stress data
- Battery life — charging a device daily is annoying. Look for 5+ days
- Comfort — if it’s uncomfortable to wear 24/7, you won’t wear it 24/7
- App quality — the data is only useful if the app presents it clearly
Garmin — Best for Serious Tracking
Garmin makes the best fitness tracking hardware available. Their watches are accurate, durable, and packed with data — GPS, heart rate variability, VO2 max estimates, sleep stages, body battery (recovery score), and more.
Best Garmin for dads: Garmin Forerunner 165 (£200–250). These hit the sweet spot of excellent tracking, GPS, and reasonable price.
- ✅ Most accurate tracking on the market
- ✅ Excellent GPS for running and cycling
- ✅ 7–11 day battery life
- ✅ Body Battery recovery score is genuinely useful for busy dads
- ✅ Durable — built to last years
- ❌ Higher upfront cost
- ❌ App (Garmin Connect) can feel overwhelming at first
- ❌ Less stylish than Apple Watch for everyday wear
Best for: Dads who run, cycle, or do structured training and want the most accurate data available.
Fitbit — Best Value for Everyday Tracking
Fitbit (now owned by Google) makes excellent entry-level and mid-range trackers. Less accurate than Garmin for serious athletes, but more than adequate for a dad who wants to track daily activity, sleep, and basic health metrics.
Best Fitbit for dads: Fitbit Charge 6 (£120–150). Good sleep tracking, heart rate, stress score, and Google Maps integration.
- ✅ Good value — solid tracking at lower price
- ✅ Excellent sleep tracking
- ✅ Clean, simple app — easy to understand
- ✅ Slim, comfortable to wear daily
- ✅ Google ecosystem integration
- ❌ Less accurate than Garmin for GPS activities
- ❌ Some advanced features require Fitbit Premium subscription (£7.99/month)
- ❌ Battery life shorter than Garmin (4–7 days)
Best for: Dads who want solid everyday tracking without spending a lot or being overwhelmed with data.
Whoop — Best for Recovery Tracking
Whoop is different from the others — it’s a subscription-based wearable (no screen, no GPS) that focuses entirely on recovery, strain, and sleep. The hardware is free; you pay £20–25/month for the service.
The core insight Whoop provides: your daily “recovery score” based on HRV, resting heart rate, and sleep. This tells you whether today is a good day to push hard in training, or whether your body needs rest. For a stressed, sleep-deprived dad, this data is genuinely valuable.
- ✅ Best-in-class HRV and recovery tracking
- ✅ Worn on wrist, bicep, or calf — very comfortable
- ✅ No screen means no distractions
- ✅ Excellent sleep coaching
- ❌ Subscription model — expensive long-term (£240–300/year)
- ❌ No GPS, no step counting, no smart features
- ❌ Requires commitment to get value — data improves over time
Best for: Dads who train regularly and want to optimise recovery, or who are serious about understanding their sleep quality.

Matt’s Pick for Most Dads
Garmin Forerunner 165 — the best all-round choice. Accurate, long battery, no subscription, excellent recovery tracking, and GPS for when you start running or cycling. Built to last years, which makes the upfront cost very reasonable over time.
If budget is tight: Fitbit Charge 6. Excellent sleep and daily activity tracking, simple app, no ongoing costs unless you want Premium.
If you train seriously and sleep is your priority: Whoop — but only if you’ll commit to it long-term.
