    We owned previous versions of the Philips Sonicare toothbrushes. This is definitely and upgrade with app support. And while the app is cool, it’s hardly necessary.

    Great results and helps motivate and track daily dental hygiene. Wish it tracked on the app without opening it while brushing. Would suggest purchase to anyone.

    Works in conjunction with an app that maps out your brushing and tells you when you're "complete" with a brushing (which sometimes feels like a really long time)
