One of the lowest paying mobile application is this Slidejoy. They give only 20 carats per day, and that can redeem only when 2000 carats are collected. 2000 carats equals 2 dollars which is very very low. Moreover the redemption mode is only paypal, and many people are not having paypal accounts because of RBI conditions for security purposes. And it takes a long time of days for redeeming and that too if one cannot take in paypal its not possible for that person to enjoy that reward atleast in any form even not in gift cards like Amazon.
