Ladoo gives you free talk time but you’ve to complete few challenges in order to avail those talk times. You have to install applications and use them in order to get the credits. But the drawback is that the earning which you get on installing the app is not very good. You get around 5-7/rs ( average) per app. That too comes with conditions, like keeping the app installed for 15 days or 10 days etc etc. You can also earn by referring to your friends. The amount that you get on referring is 5rs. Which is very less. It’s just waste of your data and time doing all this thing. Don’t install this app.
