What attaCHbox does
attaCHbox is a companion app for museum visits. It holds a set of short interactive activities that run alongside the exhibition: you open one on your phone, work through a handful of screens, and it changes how you look at what’s in front of you.
We’re not going to tell you what’s inside them. That’s the point — each activity is built around discovery, and knowing the ending in advance takes the experience away. This guide covers only the mechanics: how to get in, how to move through, and what the buttons do.
Each activity takes a few minutes. No prior knowledge needed.
1. Install the app
attaCHbox is available on Google Play. Search for attaCHbox META MUSUEM.
2. Find your way around
The app has two tabs at the bottom of the screen, and nothing else to learn:
- Activities — the list of everything available to you
- Scan QR — the camera, for codes you find in the exhibition
Every activity screen also carries a language selector in the top-right corner. Tap it to switch language at any point; you don’t have to start over.

3. Open an activity
There are two ways in.
From the list
The Activities tab shows a stack of cards. Each card carries a title, a one-line description and a tag telling you which programme it belongs to. Tap Open activity on the one you want.
By scanning a code
Open the Scan QR tab and point your camera at a code. You’ll find these on labels and panels next to specific objects in the exhibition. Line the code up inside the frame and the app opens the activity attached to that object.
This is the route the app is really designed for: it means the activity you get is the one that belongs to the thing you’re standing in front of.

4. If you’re asked for an ID code
Some activities open on a short introduction screen with a field marked Enter ID Code. The Start the experience button stays greyed out until you fill it in.
Check your museum ticket for the code. If it isn’t there, ask at the front desk.

5. Working through an activity
Every activity follows the same shape, whatever it’s about:
- A progress bar at the top tells you which step you’re on and how many there are in total. Activities in this release run between five and eleven steps.
- Each step asks you to do one thing — make a choice, tap something on an image, type a short answer. Take your time; there’s no timer.
- The Continue button stays grey until you’ve answered. If it looks disabled, you’ve missed a selection or an empty field somewhere above it. Scroll up.
- Some screens scroll. If you can only see two or three options, there are usually more below.
- The back arrow in the top-left leaves the activity.
There are no right and wrong answers, and nothing is scored. The app is interested in what you notice and what you choose, not in testing you.

6. Doing an activity again
Some activities are designed to be opened once. If you want to run one a second time — to let someone else have their own turn, or because you’re curious where a different choice leads — you can unlock it again:
⋮ menu (top right of the Activities screen) → Settings → Reset opened activities

Worth knowing: the paths really do branch. Two people going through the same activity can end up somewhere quite different.
Before you go in
Download the app, check your ticket for a code if you have one, and then — mostly — put your phone away until you see a QR code worth scanning. attaCHbox works best in short bursts, standing in front of an object, rather than as something you read straight through.
