Question about Philips Sonicare 9900 Prestige
Does the app differentiate in the evaluations according to brush head, i.e. can I share a toothbrush with my wife and still only receive evaluations for me personally, or are all evaluations then a mixture of the two brush heads used?
Helpful answer
I have since purchased the toothbrush myself and unfortunately have to confirm that the data is completely mixed: When two different brush attachments are used with the same Sonicare device, it synchronises the use of all attachments to the mobile phone.
As I see it and understand it, the toothbrush and the device have no intelligence and do not store any data, but only sensors that send data to the paired mobile phone for evaluation and storage. That is, as long as the paired mobile phone is yours, they are not mixed.
