I downloaded Instagram when it first came out in October of 2011, and I`ve been obsessed ever since.
Basically, what you do is take pictures or post them from your photo library, add an effect, then post it, and your followers can like it or comment on it.
There is also a popular page, if you get about 50 likes in a short period of time your picture will be posted to the popular page.
Instagram is an app only, there is no Instagram website, but there are a few websites that have been made (not by Instagram) so that you could check your Instagram on your computer.
I really like Instagram and I hope one of my pictures make the popular page one day. I rate this app 5/5!
Check it out!
