The worst application for messaging as because it hangs a lot and that is why many peoples do not use this application, none of my friends use this application and even who installed it earlier ave also deactivated their accounts, it is best known for its stickers but I would never suggest this application because it lags a lot even when you are sending stickers.
I sent an image to one person it was showing that message has been sent but the receiver says that the image has not been received yet.
It takes a lot of space in your mobile and requires a lot of RAM to operate.
The design and layout of the app is quite good
Thank You
