I am just using this app since last 1 month because before that people said to me that this is not so good. So when I started using this app, first took some minutes to get aware with every features of it.
The filters in this app is amazing and I am just loving this feature moreand also new filters come on updates. The privacy of your chat which this app has, is also very secured, our message is deleted from both side after the reader opens it. If anyone is taking screen shot of the chat box of yours in his phone, then you will get to know about this activity.
Overall this app is amazing for the text message, video calls, audio callsand lot of features it has in it. So I suggest you to go for this app.
