If you using whatsapp and facebook and then you probably know about this app names as SNAPCHAT.
This app is basically design for funny live camera filters on the go in realtime.
You can also add story as you can add in instagram and facebook and it is pretty cool and funny . I personally recommend you to try this one out .
But it takes lot of time to use this app correctly and use its all features and im a beginner and I recently installed this app so I dont know about many more features but as far as I know very descent and beautiful app and it is famous for its live filters and mine favourite is pikachu.
Apps layout and design is very classy and beautiful
Go and try this one out.
