Timehop, a_popular service that ‘goes back in time’ to show you past posts on various social media sites,_has finally landed on Google Play for Android devices. The Android app brings together your old photos and posts from your iPhone (if you have one), Facebook, Twitter, Instagram and Foursquare and replays them accordingly. The Timehop app was released in late 2011 only for iOS devices. Last month,_the company removed Timehop Messages, its in-app messaging system, citing low usage — but teased plans to release_some new social features to help with sharing.
