Ratings and reviews

it's a bog standard lights and shapes test of the type that have been available freeware for decades - only this one has a paywall. if you want money for your app just charge a couple of quid up front otherwise physical flashcards are still a better option.

I've paid for this service, not only this app but the other 2 and there are so many wrong answers in it and the layout is poor. It is a good go to, for practice, but not when so many answers aren't correct. Spend some time and go through the questions and answers, please.

Looks good BUT MANY errors. Please don't teach the wrong things. Look through the reviews, I am not the only one who spotted errors. VERY BAD 👎. Emailed them without any reply. Anyway, I paid for it.
