ThenHere helps you return to the places hidden inside your photo library. Open the map, find old photos around you, and choose a memory you want to meet again. When you arrive, use the camera overlay to align the old photo with today and capture the same place through time. What you can do: • Discover photo memories by nearby place • Switch between map and grid exploration • Swipe through multiple photos from the same spot • Retake an old frame with a transparent overlay and guide grid • Save then-and-now comparisons Your photos stay on your device. ThenHere uses photo location metadata to help you revisit real places, not to upload your library.
