Finally!!! Brilliant! I have the complete series all ...... – LÜK Review

The way to age 7. I was pleasantly surprised to see variation enabled within the same "book page" this is really super, so ill request that future updates have even more which will greatly enhance the deep learning while lowering the probability of memory effect via repetition of the same content within the same book and page. Would also love to see content for older children as well. Glueckwunsch!
