Bad value proposition
I'm using and reviewing this newly set up app with a brand new io 8, because without a brush, this app would be useless. This app and the expensive io's software are buggy, inconsistent, unreliable and even missing some important basics, while the AI tracking is a promise of a gimmick that's so badly made it tells you misleading nonsense (it doesn't really work, as many others have pointed out). I can track my brushing perfectly in the mirror with my eyes. Almost every time I open this app, it plays a long, frivolous snowfall animation for me to sit through. The app UI is busy with offered features, none of which feels like it's worth my time and data investment and I have no faith left in Oral-b's ability to deliver on them. While this app properly syncs all brushing sessions from the io brush, it fails to sync on average 1 out of every 5 brushing sessions to apple health - I have to add those manually. The history page is a low-info-density list that soon grows unwieldy. If the app is not used for brushing (unguided session), the io only records (and later syncs) the duration, nothing else. This is dumb and disappointing. It would be a chore to use a smartphone and this app every day each time I brush my teeth. I only want to open this app when charging the brush and they should sync everything then. The brush replacement reminder is designed with the assumption of 2x2 minutes of brushing every day - if your brushing routine is different from that, the reminder will be misaligned and useless, and it's unchangeable. It should instead be based on accumulated duration in operation. The vibrating pacer is also unchangeably set to 4x30 seconds - it would be very useful and easy to change it to 6x20 seconds, but that's not an option (even despite the fact that this io 8 differentiates between 6 zones in the mouth when brushing in a guided session with the app). Oral-b paywalls the 6x20s pacer behind the price of the most expensive io 10, as if it were a luxury feature. On the io's screen, the battery gauge is only shown after brushing sessions (with many seconds of delay), otherwise it's impossible to check it on the handle (when away from a plugged-in charging stand). Battery readout is useful basic info that should always be accessible. Oral-b should've taken this further with simple math (or machine learning): based on how much battery charge the user's sessions have consumed in the past, and the current charge level, extrapolate and display the number time
