I’ve got an ultrasonic one, no app needed. It detects when you apply too much force, and if you do use the app - again, not needed - it can track your brushing habits and tell you when you’re missing spots. I would not have bought it without my employee discount, though. I think the $30 ultrasonic ones with no seriously fancy stuff are still good, though.
