Buying your first fitness tracker: five specs that actually change the experience
GPS, battery life, sleep tracking, app support and comfort. What to check before paying for features you will never use.
A fitness tracker is worn more than almost anything else you own, which makes comfort and battery life more important than the length of the feature list. Here is the short version of what we check first.
1. Built-in GPS or phone-tethered?
Built-in GPS lets you run without your phone and produces a cleaner route record. If you always carry a phone, tethered GPS is fine and usually cheaper.
2. Battery life with the features you will use
“Seven days” often assumes notifications off and no GPS. Read the small print for always-on display and workout use. A tracker that needs charging every night is a tracker you will stop wearing.
3. Sleep tracking you can interpret
Sleep stages are estimates, not medical measurements. Look for a clear nightly summary and trends over weeks, not a single score that changes your mood every morning.
4. App support and export
Check whether your data can be exported and whether the app works with the phone you own. Subscription-only insights are becoming common; decide whether that is acceptable before you buy.
5. Comfort and strap options
A 37 g band disappears on the wrist; a larger watch does not. Look for standard or widely available strap sizes so you can replace a worn band instead of the device.
Start with our Fitbit Charge 6 listing for a compact option, then compare battery and GPS specs in the Fitness & Sports department.
