Photo Calendar turns your camera roll into a year of calendar pages. It reads each photo's capture date and picks a cover for every month, so the March trip lands in March and the July birthday in July. Swap any photo and the page recolors to match. One page, three places: a Lock Screen wallpaper at your screen's native resolution (Live Photos move), a Home Screen widget that flips on the 1st, and a 12-page 300 dpi PDF to print. On-device, no account. iPhone and iPad.
