The timer feature is very helpful. The ads running at the bottom of the screen are of limited use since its hard to read and brush at the same time. As another user said, it would be helpful if one could enter flossing, rinsing, and tongue cleaning data manually. Similarly, the tracking of those data isnt very good. It loses count every week, making it look like I missed days.
Finally, for those who found that the vibration feature vanished after the update, just go into settings to reactive it. It worked for me after I did that.
