Installation
Current status
| Platform | Status | How to get it |
|---|---|---|
| Android | Open testing on Google Play | Link on the download page — no invitation |
| Windows | Installer download | Link on the download page — no invitation |
| iPhone and iPad | Open testing on TestFlight | Link on the download page — no invitation |
None of these require an account, registration or cloud storage. The app has no sign-in — your data is created on the device and stays there.
Requirements
| Item | Value |
|---|---|
| Android | Android 7.0+ |
| Windows | Windows 10 or 11, 64-bit |
| iPhone and iPad | iOS 15.5+ |
| Network for sync | A shared local WiFi or hotspot. No internet needed. |
| Account | None |
The app works completely offline. You only need a connection in two cases: searching for a song on the web, and importing one from a web address.
How to get the app
Android
Play shows at the top of the app's page that this is a test build. That is correct — there has been no public release yet.
Windows
Two things may surprise you during the install and at your first band session:
- "Windows protected your PC". The installer is not digitally signed yet. Click More info → Run anyway.
- A prompt about network access at your first band session. Allow it for private networks, otherwise the phones in your band will not see you.
Your library lives outside the installation folder, so neither an update nor an uninstall deletes it. To update, download a newer installer and run it.
Sync, ChordPro, PDF, MusicXML, backups and pedal control all work on Windows exactly as on mobile.
iPhone and iPad
- Install the TestFlight app from the App Store. It is free, and it is how Apple hands out test builds.
- Open the download page and tap the TestFlight link. Testing is open, so you join yourself — no invitation from us is needed.
- Eutepio installs from TestFlight and updates arrive the same way.
Eutepio is not on the App Store yet — searching for it there will not find it, the link is the only way in. A TestFlight build is valid for 90 days; a newer one arrives before that runs out.
Almost everything that works on Android works on iPhone and iPad. Two things do not yet:
- The automatic daily backup. iOS handles this differently and it is coming via iCloud Drive. Manual backup works on both.
- Sending attachments into a song from another app. On Android you can share a PDF, a score or a photo straight into a specific song; on iPhone you add them from inside the app for now.
A concert sent as a file opens on both platforms.
First launch
On first open you go through the onboarding wizard:
- Five welcome screens introducing the app
- Your name — used as your identity during sync, so bandmates can recognise you
- Instrument — pick from the list or type your own
- Demo content — you can load sample songs and a setlist, or start with an empty library
Permissions
The app asks for permissions only when it first needs them.
Android
| Permission | What for |
|---|---|
| Camera | Photographing sheet music for attachments and OCR |
| Internet, network state, WiFi state | Sync between phones on the local network |
| WiFi multicast | Finding the other devices on the network automatically |
| Wake lock | Keeps the screen and CPU alive during a gig and during sync |
| Foreground service + notifications | Keeps sync running when the screen is off |
Camera and MIDI are both declared optional, so the app installs on devices that have neither.
iOS
| Permission | Prompt |
|---|---|
| Camera | Taking photos of sheet music and recognising text (OCR) in songs |
| Photo library | Adding photos of sheet music and song artwork |
| Local network | Eutepio uses the local network (WiFi) to sync with your bandmates. Data does not leave your network. |
The app never asks for location, microphone or contacts — those permissions are not declared in the project at all.
