House projection mapping app: decorate your home from your phone

House projection mapping app EasyMapper Studio turns the front of your home into a display you can redecorate from your phone — a haunted mansion in October, a gingerbread cottage in December, a birthday marquee in June. Map the facade once from an iPhone or iPad, no laptop, and every occasion after that takes about as long as changing a playlist.

1. Fix a projector position you can return to: a tripod spot marked with tape, or a shelf behind a front-facing window.
2. Add a layer for each architectural feature — every window, the door, the garage, the wall itself — and drag each layer's corners until the light sits exactly on the real edges.
3. Save the map and swap content per occasion. The geometry of your house never changes, so the corner-dragging work you do once keeps paying off all year.

• Halloween: ghosts in the windows, a portal around the door, fog crawling across the brick — see the Halloween projection mapping app page and the built-in Halloween loops.
• Christmas: snowfall across the facade, warm hearth glows in each window, animated light strings along the roofline with no ladder.
• Birthdays, graduations, match nights: names, years, team colours, photo slideshows — content that is about someone, which physical decorations can never be.

A 3,000+ lumen projector is comfortable for a whole facade; single windows need far less. Any projector with HDMI or AirPlay works — our projector guide narrows it down in 30 seconds, and the connection guide covers adapters.

Free to download; Premium ($7.99/month or $39.99/year, with a trial) unlocks everything. One subscription replaces a desktop mapping license and the laptop it would need.
