This is very good and most lovable app and data saving video calling app in android but in windows phone and systems you cant get the facility of video calling. I heard this is because microsoft hadn’t allowed them to input video calling options. if we keep this video and audio calling terms aside you can chat with your friends in a customized manner even though there are problems with this this is the only social media which had connected nearly 1/3rd of our world. if you are using a pc then please use this on browser this will give you more options
