This app is really a good battery drainer
Ya I know it lets you to make free calls and free messages
But some people dont know its not free at all
Guys it works on internet
It makes the calls using the same technic used by fb messenger or whatsapp
So ofcourse your net balance will be deducted
But for the people who dont have VOLTE in their cell phone and are using reliance jio sim have no other option so its okay for those people
But for people who are in other networks I dont recoomend this to you
