Question about Philips Sonicare DiamondClean 9900 Prestige
Does the toothbrush also work without an app if necessary?
Helpful answer
I always clean without the app. I haven't even downloaded the app.
Only very limited. The cleaning modes can only be switched via the app. The Sonic Care 9000 would be the better choice in every respect without the app.
In the beginning, the app was quite interesting, but I haven't used it for a long time.
