Tap Download & install. If the browser warns that this kind of file can harm your device, choose Download anyway — it is our own signed app.
Open the downloaded file: tap the download notification, or find the .apk in the Downloads folder.
Android asks for permission to install apps from this source (“unknown source”). Tap Settings, turn on Allow from this source, then press back. This is asked only once.
After the permission a second screen appears: “Scan app?” (Google Play Protect). You may let it scan — but we recommend Install without scanning; the install starts right away.
Tap Install, then Open. The app is now on the home screen as LedPlayMeter.
Connect to the player
Put the tablet or phone on the same Wi-Fi as the PC running LedPlayMeter.
On the PC open Mobile remote (tablet/phone) and click Start pairing.
In the app scan the QR code or type the 6-digit code. The code is valid for 5 minutes and can be used once.
Not published on Google Play — the app is installed straight from this page. It only talks to your own LedPlayMeter PC: no account, no cloud.
