OK, but….

The concept of the app is OK, it helps our son in learning to read the clock.
However, in the French version, there are a lot of mistakes in the explaining texts, mxing up left and right for example, which makes it tricky for him to read through on his own and get a correct understanding. I would recommend to the developers to do a proper read through and correct the mistakes, since it is so important to avoid confusion with smaller children.
Also, the „moins le quart“ and „et le quart“ are not used when the app tells the time, unfortunately.

In addition, the app has hung up my mac twice in a short time so there seem to be some technical bugs to be fixed as well. I’m running OS X 10.9.

I hope these things get fixed, because in essence, the concept is good and our son likes playing with this.
