Hey guys. Just to let you no about this awesome app thats just come out! Its called Tap 'n' Slide! This app challenges your reactions whilst listening to some upbeat music. I have tried the other apps that tried to do this but have failed miserably! This app is the best out there and has had me playing it for hours... The app is £1.19 which i believe is well worth it for hours of enjoyment it has brought me on long journeys so why not give it ago and see what you think!
