By using GPS to log your daily activity, matching your photos to the timeline, and looking up locations using Foursquare, the new app called HeyDay is able to create a photo journal of your life. The app tracks and remembers everything you do and everywhere you go in order to create a photo journal of your life which is presented in a neat grid.
Heyday for the iPhone is a little like the great (and defunct) Everpix flashback feature, which showed you photos you took on this day in history. Only Heyday goes one better: it doesn’t just remember photos, it remembers places, and weaves the two together into a rather neat little automatic journal.
