Sync your stats wirelessly to your smartphone or computer from up to 20ft away and view your progress in easy-to-read charts and graphs. See daily stats, time of day, day of the week, and exercise mode on the OLED display, as well as who’s calling you with the synced caller ID feature. Get the most out of your R. E.
