It shows how little you need to build something people share: photo metadata the phone already wrote, a map, and a link.
Upload a handful of trip photos and the site reads their location and date, then builds a roll your friends play: drop a pin on a map, pick the month and year, see how close they came. Photos without metadata can be labelled by hand. Rolls are shared by link and delete themselves after 30 days. The maker built it as an anniversary present for their wife. Note that anyone with the link sees where each photo was taken, and there is no privacy policy yet.
