6. Garmin Vivofit 2 with Heart Rate Monitor
Functions: sensor compatibility, calorie burn tracker, heart rate monitor, distance tracking
This is one of the best bets when it comes to fitness trackers, as it comes with a simple, easy-to-navigate interface and a clear display that works well for anyone with vision problems. It’s also waterproof, so you can use it in the shower or during an occasional swim. It’s relatively inexpensive and looks great.
