  • Fantastic Watch

    It reminds me that I have steps left per hour or that I need to move. Also I like that it keeps track of heart rate

  • Love It

    Helps keep me on track. Had the Charge 2 prior to the Ionic and liked it as well, but however, the Ionic has so much more to offer.

  • Great Features

    1st purchase of a Fitbit & the Ionic was a great choice. Easy setup w/ IOS iPad. Fitbit app is a gem and keeps me updated on all info. Purchased for water aerobics. A great motivator to get up & move. Prompts to get up every hour & make at least 250 steps. Sleep pattern, alarm, heart rate, water proof, app, steps & ease of use has been a wealth of help & information. The battery charges super quick & stays charged 5 days. It is a bit oversized for a woman of any size but it is something I can overlook. Very happy w/ purchase.
