Ratings and reviews

great, easy to use app that I keep at all times, helped me before getting my license and after to brush up on my knowledge! thank you!

this app should be a reminder to all not to rely on scanty information... many of the lights don't show in the test questions. save your £4.50, it's not worth it.

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.
