The App Store is home to plenty of digital journal tools, but all of them require effort from the author to be useful. Heyday solves this problem in a very elegant way – and one that actually makes us want to participate. The free app converts existing photo libraries from an iOS device into an automatic journal of your life, complete with geolocation data and time stamps. The speed and accuracy at which Heyday accomplishes this task is nothing short of amazing, but the occasional coarse location can be confirmed or updated as needed. On days when photos aren’t taken, the app continues to work in the background with minimal battery impact, capturing key places visited.
