It is the data saver app
There are various ads on the data back so it is not work properly and hang our mobile and it takes the storage and the memory. In the app our data stores only 10 MB per day this is very bad and this app we use this 10 MB data in various ways like used for FB for 2 MB and WhatsApp for 5 MB
That’s concept I don’t like and the invite and earn of this app is also very bad and the recharges are not so big only the validity of this recharges is high that is not so good
