Photograph every stud, wire and pipe before the drywall goes up — then know what's behind the finished wall years later. BehindYourWall turns a 30-second walk through an open frame into a permanent record of your home. The next time someone mounts a TV, adds an outlet or chases a leak, you look instead of guess. What you get: • Photos, video and voice notes, filed room by room — works with no signal • Pair the before and after of a wall, then slide between them • AI labels what's in the framing — Romex, copper, PEX, drain • Photos sync to YOUR own Google Drive or iCloud, never our server • Pay once per home. No subscription. No ads. No tracking. • Yours to pass on — share the folder with the buyer at closing BehindYourWall helps you remember what's behind a wall. It does not replace a professional stud finder, electrical tester, or licensed contractor. Always verify before you drill. Questions: support@behindyourwall.com
