IMO is an app designed for video chats. The concept of the app is good but there are several negative points in this app.
The first and most important is that the video quality which this app offers is very very bad. I used the app with a 4G connection but then also the video quality was very poor.
Second, the voice in the video calling is very loud and unclear. You cant put the volume down even if you want. The sound at minimum volume level is quite loud aaand unclear which is very irritating.
So I suggest you guys not to install this app.
