11 Fitness Tracker Features That Matter Most

3. GPS Integration and Accuracy

Built-in GPS frees you from carrying a phone for outdoor runs and rides, and it provides pace, distance, and route maps. Some trackers rely on your phone’s GPS, which saves battery on the watch but ties accuracy to the phone’s signal and placement. Premium trackers usually include standalone GPS with better signal handling and occasionally multi-band support for denser urban areas. Accurate GPS is essential for runners and cyclists who want reliable pace splits and route data. Urban canyons and tree cover can still cause glitches, so look for brands that offer signal smoothing or route correction in post-processing. If you compare models, note whether GPS is powered by a single satellite network or multiple systems (GPS, GLONASS, Galileo), since multi-network support can improve accuracy. For casual walkers, phone-based GPS might be adequate. Serious outdoor athletes should favor trackers with dedicated, built-in GPS and robust post-run mapping tools.
