Snapchat the app which is tremendously famous amongst the people according to me is just a waste of time. Thia app should not call itself snapchat. It is similar to other chatting app.
Just to make it different they have add extra filters in it. First when I hear about this app it sound interesting because of its name. I thought thatvby sending a snap only then we can chat as per its name says but it was not the case. You can chat simply like other chatting apps just the difference comes that if u don’t save ur chat the message will be deleted after u see it.
No doubt on its security as u can’t see people friends and if someone is taking screenshot from ur message this app will let u know. But it is not about security it is about chatting and when u chat in snapchat u get bored opposite to other apps. Lots of improvement needs to be done and I hope they will figure out something to make it interesting and exciting.
