I am using slidejoy from past one year and exprience of mine with this app is good.
Till now I have earn around$40 for just using this app in normal mode.
How this app works:
This app will give you carats( 1000 carats=$1= 64 ruppees) each time you unlock your phone.
Actually just above Your phone pattern their is slidejoy window pop up where some news and some ads are displayed. Its upto you to read or just reject these stuffs but you will get credit each time you unlock your phone during normal mode( normal means unlocking your phone only for some purpose) .
U can earn some exta bucks by playing games, referrrings, surveys etc( only if you have time) otherwise normal use this app, that is unlocking phone will pay you carats each time for sure.
Use this app the way you are using your phone everyday. Dont focus so much on this app.
Earning process:
Its little bit slow process but genuine and not fake.
U will get benifit from this app during long run.
Payment transfer:
U can transfer your earning to your paypal account then to your bank account in a single click. I would like to say that install this app in your phone, but dont think that I will earn some good amount of money overnight. Its illusion of mind.
Its enjoyble and benificial to you.
