I'm not familiar with the apps, how does it measure and improve your dental health?

The idea is to help focus brushing on specific teeth or quadrants, and it uses Bluetooth to know when the brush is on or off. Maybe it signals when you push too hard and the brush pauses for a second as well.

To my knowledge it does not know where you are in your mouth when brushing (positioning via accelerometer/gyroscope), so a synchronized start would likely give similar results.
