# House projection mapping app: decorate your home from your phone

> House projection mapping app for iPhone and iPad: map your facade, windows, door and garage once, then swap content for every holiday and event.

Published 12 September 2026 · By Abhinav Bhardwaj

**TL;DR:** Need: an iPhone or iPad, a 3,000+ lumen projector for a full facade, EasyMapper Studio. Map the house once in an evening; after that, decorating for any occasion is a content swap.

**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.

## How it works in three steps

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.

## What can a mapped house do?

- **Halloween:** ghosts in the windows, a portal around the door, fog crawling across the brick — see the [Halloween projection mapping app](https://easy-mapper.xyz/use-cases/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.

## What you need

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](https://easy-mapper.xyz/projector) narrows it down in 30 seconds, and the [connection guide](https://easy-mapper.xyz/connection) covers adapters.

## Price

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.
