What Slidejoy does, basically, is put ads onto your lock screen on your Android. What's so great about that? You might ask. Well, you won't be watching the usual, boring and invasive ads that assault you while you're playing an Android video game, but rather advertising that's specifically tailored and selected just for you that you might even grow to enjoy and appreciate in some cases.
Once you've activated and configured Slidejoy, all you need to do is turn on your screen and watch an ad. Swiping right, you'll unlock your device, and it's as easy as that. But, if you swipe left, you'll get more information about the services that were advertised.
Slidejoy is a fairly interesting app, thanks to which you'll earn money without having to lift a finger. Also, you'll get the chance to donate your earnings to a number of different non-profit organizations and NGOs, although, you could also just keep it for yourself–up to you.
