Good app but Needs to be fixed.

I like this app. I wish it would teach the very basics like the alphabet, numbers, days of the week, months etc.

I wish they would fix the app. I had a 30 day streak and at day 31 until today, which would be day 36, it wont register anything Ive done. I cant collect the daily reward and it crashes when it loads. Whats going on with this app?? It was working fine until the August 11th update.
