Your iPhone records your life with photos. The app PhotoRanking Free makes special rankings about you using your stored photos, like Highest place top 100, Closest to the North Pole top 100, most far places top 100 and etc. You can see not only photos of these rankings but also a place of the photos on the map, altitude, time, distances. Enjoy a new style of exploring photos of your life by PhotoRanking Free. Usage: This app requires stored photos in your iPhone. When you launch the app for the first time, the app will make rankings ( this process takes a little time.) Then, you can explore photos sorted in the rankings. You can update the rankings by touching update button on the up-right corner, when you add/remove photos in your device or your location is changed. Free version displays Advertisements.
