Tests are repetitive. Took away my paid-for premium purchase after one day. Clicked on web site and chrome informed me that their site is malicious.

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.

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 ๐Ÿ‘Ž. Emailed them without any reply. Anyway, I paid for it.
