Wanderoll turns the trips already sitting in your camera roll into travel film — automatically, and entirely on-device. It reads the time and location in your photos, clusters every trip into its own "roll," lights up a footprint world map, and builds a swipeable year-in-film recap. No manual logging like other travel apps. No account. Nothing is ever uploaded — it all runs on your phone. The best part: it works retroactively. Install it and a lifetime of travel is organized in the first minute.
