Kids don't like brushing their teeth. That's why my daugther and me came to the idea of creating a motivating teeth brushing timer which sets a good example.
When you squeeze the rubber duck, the timer starts and the animation shows the 13 phases of brushing teeth nicely one by one. Whenever the phase changes, the duck squeaks once as a signal. That's all.
But it works - it helps children and parents to make sure teeth brushing gets done correctly.
We had a lot of fun to realize the idea, but it also took quite some work. Proper teeth brushing can save a lot of money, so this app is not just for fun, but has an actual use. That's why we set a little price for it - for the pocket money piggybank.
