As with the last app I reviewed, there is a handy finger to give you a hint should you need it.
The first game I played was number recognition and ordering to 100. If you get the order wrong you get an 'oops', but then continue from where you were, which is good.
The time game is a simple match the analogue to digital time. I only played this briefly so it may go past hour times. It scaffolds learning by showing the time as you move the small hand, then the train chuffs away if you match the time correctly.
The measuring lab had suitably scientific kooky music too. If you weren't watching your child at play, you would know exactly what they were doing.
