            Release assets are published for all supported build targets:
            - Android (`.apk`)
            - Linux (`.tar.gz`)
            - macOS (`.dmg`)
            - Windows (`.zip`)
            - iOS unsigned (`-ios-unsigned.ipa`, `-ios-runner-app.zip`)

            Windows status: currently unusable. The BLE stack on Windows is broken, so BLE features do not work.

            iOS manual signing and install:
            1. Download `*-ios-unsigned.ipa` (or `*-ios-runner-app.zip`) from this release.
            2. Re-sign it with your Apple Development/Distribution certificate and provisioning profile.
            3. If you used `*-ios-runner-app.zip`, create a signed `.ipa` from `Runner.app` during signing.
            4. Install the signed `.ipa` on your iPhone using Apple Configurator 2 or Xcode (Devices and Simulators).
