Instagram is a free photo sharing app that lets you take pictures and apply cool, retro-looking filters to them.
The filters make it easier to show off your photos on Instagram, which also happens to be a social network that lets you follow your friends’ photos as well as celebrities and brands.
Instagram is a photo-sharing mobile app that allows users to easily take a picture, apply a digital filter, and share the image on a variety of social networking services, including Instagram and Facebook.
Users can also “like” or “hashtag” other users’ photos.
The app was developed by Kevin Systrom and Mike Krieger in 2010, and the two sold the company to Facebook in April 2012 for an estimated $1 billion.
