Fitbit Edge vs Samsung Galaxy Fit3 specs comparison
These two fitness bands target different budgets. The Fitbit Edge offers built-in GPS, ECG functionality and more advanced health tracking, while the Galaxy Fit3 covers everyday activity, sleep and heart rate monitoring at a considerably lower price. Samsung also promises up to 13 days of battery life, compared with seven days for Fitbit. The Edge is more capable, but the Fit3 makes sense if you only need the basics and use an Android phone.
