Canโ€™t activate

Asks for a phone number to send an activation code to. Never arrives.

Great action for cleaning teeth / app is fine

The brush does a great job of cleaning teeth. High speed action is soft but effective. Mouth feels good.

The app is fine. I donโ€™t understand what issues are. Note that to turn on brush you must hold power button for at least 5 secs when it is stored in travel mode - prevents accidental triggering.

App needs priority

Usually anytime I open the app it takes forever or doesnโ€™t work. For an electric toothbrush that needs to work, it kind of needs to be a priority for the company

It never sends a confirmation code to login

The app is absolutely useless because when you first launch it, it asked you to login and gives you two options. One is to enter your phone number and the other is to enter your email address then you havenโ€™t sent you a code that you need to type in within 60 seconds and the code is never sent. I tried both options. I tried my phone twice and I never received a text message and I tried to email once and I never received the email. I like the toothbrush I really have no idea why you need an app for a toothbrush, but I thought Iโ€™d try it.
