Frequently asked questions
Do smartwatches work with both iPhone and Android?
Some do and some don't. Apple Watch only pairs with iPhone, while most Garmin, Amazfit and Fitbit watches work with both iOS and Android. Samsung Galaxy Watches work best with Android. Use the compatibility filter to match a watch to your phone.
Do I need built-in GPS in a smartwatch?
If you run, cycle or hike and want accurate distance and pace without carrying your phone, choose a watch with built-in GPS. For everyday step counting and notifications, connected GPS (using your phone) is usually enough and costs less.
What is the difference between a smartwatch and a fitness tracker?
Smartwatches have larger touchscreens, run apps, and show notifications, calls and payments alongside health tracking. Fitness trackers are smaller, cheaper and focus mainly on steps, heart rate and sleep with much longer battery life.
