# Halloween projection mapping app: map your house from an iPhone

> Halloween projection mapping app for iPhone and iPad: map your windows, door and garage in minutes, no laptop, with built-in Halloween loops ready to play.

**TL;DR:** Need: an iPhone or iPad, any HDMI or AirPlay projector, EasyMapper Studio. Time: about 20 minutes for a whole facade. The latest update ships Halloween loops built in, so the house is haunted the same evening you install.

**Halloween projection mapping app** EasyMapper Studio puts ghosts, silhouettes and lightning onto your windows, front door and garage — all from an iPhone or iPad, with no laptop balanced on a windowsill. Drag each layer's corners onto the real edges of the surface, drop a loop on it, and the house is haunted.

The latest update adds a set of Halloween loops built into the app, so you can go from installing to projecting spooky content the same evening — no hunting for downloads before the first test.

## How it works in three steps

1. **Connect the phone to the projector.** A USB-C or Lightning HDMI adapter, or AirPlay if the projector supports it. Our [connection guide](https://easy-mapper.xyz/connection) covers every combination.
2. **Add a layer per surface.** One for each window, one for the door, one for the garage. Drag the corners until the light hugs the real edges — that precision is what makes it read as haunted rather than "a projector pointed at a house."
3. **Fill each layer and press play.** Use the built-in Halloween loops, your own videos, or live shaders. Save the map once and reuse it every October — and for Christmas.

## What you need

A projector (3,000+ lumens is comfortable for a full facade; far less for one window — see [how to pick a projector](https://easy-mapper.xyz/projector)), the adapter, and somewhere dry to put it: behind a front window, a covered porch, or the garage aiming out.

## Why decorators use it instead of desktop software

- **No laptop outdoors.** The whole show runs from the phone in your hand.
- **You stand at the surface while you align it,** instead of running back and forth to a desk.
- **Curved and complex surfaces** are supported, so pumpkins, columns and inflatables can be mapped too.
- **One map, every holiday.** The geometry never changes; only the content does.

## Price

Free to download; the Premium subscription ($7.99/month or $39.99/year, with a trial) unlocks everything. Compare that with a desktop mapping license plus the laptop to run it on.
