I use this application from a long time ago. I earned 3000+ carats and I use it to recharge my phone. I recharged my phone 2 times. First I recharge 25 rs. then I recharged 100 rs. some ago. In this application you just have to unlock your phone to earn carats and when earned redeemable carats then you can buy amazon gift card, flowers, mobile recharge and more. You can refer this application to your friends to earn more carats. Very awesome application and easy to use.
