Ratings and reviews

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.

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

great app! I appreciate all the team who make an effort to create this! 🫶
