The ladoo is a money earning in the playstore.
You can earn the money in this app by completing the offers.
The offers are like downloading app and open it , sometimes for more reward you have to keep the downloaded app for few days in your mobile.
The problem is the money you earn you can only use for recharges.The reward per app is low as 1-2 rs .
And the offers such as keep app for 4-5 days dont give you any reward.
The minimum recharge amount is 20 so long period is required to complete the offers and make that amount of money.
As you complete the offers in few days the amount of offers get decreases as they have limited offers only .
So this app you can consider as one time use only.
