While the title itself does a pretty good job of hinting at what the app is for, Timehop's capabilities are extensive, yet incredibly simple to use. It's considered a 'social networking app' because you can share updates with your friends not only through the news feed within the app, but also on your social networks! Timehop allows you to see your photos and updates on the exact day in history from Facebook, Twitter, Foursquare, Instagram, flickr, and your camera roll. Each day you can receive a notification when your Timehop is ready (this is done within the app settings) and explore your day in history through social media. It also includes the USA Today news history for the specific date as well! Download the Timehop app and start reliving memories, for FREE!
