I have been using snapchat for the past 4-5 days.
I think the concept of the app is good but the app is very clunky. A very good passtime and good medium to connect with your friends.
If the app is reorganized and given a new look it will be one of the best apps.
It has a 3.9 rating on play store only due to the reason that the design of app is bad.
The concept of the app is very good and one should definitely try this.
