PhilipsSonicare is, on the surface, great. Especially given that when working properly, it provides real-time and detailed feedback on where and how you should be brushing, as well as creating a record of your brushing activity. However, recent updates to PhilipsSonicare have all but made it impossible to use.
Beginning a few months ago, PhilipsSonicare started to take far longer to load, crash somewhat more frequently, have trouble connecting to the brush via Bluetooth and inaccurately record where in your mouth you are brushing. With the more recent updates, it began crashing consistently in the middle of brushing, and now, it is impossible to open PhilipsSonicare at all, rendering it completely useless. Hopefully, the team at Philips can address these software/firmware issues, because again, when working well, this is a great and innovative product/app pairing.
Additionally, Philips introduced auto-refill ordering through PhilipsSonicare a few versions back. However, they do not offer replacement tongue scrapers that are the same as the one that came with the brush originally, or even ones that are compatible with PhilipsSonicare /brush. This is the case both with the auto-refill and their online store. It would be nice if they could remedy this.
