Snapchat is an application in which you can add friends and see there stories which will disappear in 24 hours and have great filters in it. But now this app is of no use as these filters and stories features are also present in other apps we use like instagram, facebook, whatsapp so why to install special appliaction only for stories and in this chats disappear of you viewed it once, if you wants to save that that you have to long press on the a perticular message which becames very time consuming amd irritating.
Moreover snapchat uses lots of space and RAM in your phone. And takes too much of data to use. I thinks the concept of snapchat was good but its not so useful.
