Ratings and reviews

Excellent illustrations. all signals are clear and the app makes studying interactive and keeps it interesting.

I paid for the lights and shapes app only to find plenty of errors. Anyway, I am not the only one who spotted the errors. Though I did not pay for this app, I doubt it will be any better. Can download but don't pay for it.

Please i cant buy these app...my google pay is telling me to try a different card and i have ended up trying all my cards and my siblings cards too, but its still not working and i need to buy all your apps cos they are so great. Its so frustrating to me.
