Installation

Download the build for your platform from the Releases page.

macOS

1. Unzip sightings-macos-<version>.zip and drag Sightings.app to Applications.
2. The build is not yet notarised, so the first launch is refused. Open System Settings → Privacy & Security, scroll down and click Open Anyway (older macOS: right‑click the app and choose Open). This is a one‑time step.
3. Plug in the DCA75. No driver is needed; the app connects automatically.

Works on Apple silicon and Intel Macs. libusb is bundled inside the app.

Linux (x86‑64)

1. Extract sightings-linux-x64-<version>.tar.gz anywhere, e.g. ~/Apps/sightings.

2. Install the udev rule once so your user can open the unit without root:

   sudo cp 60-dca75.rules /etc/udev/rules.d/
   sudo udevadm control --reload && sudo udevadm trigger
   

3. Plug in (or replug) the unit and run ./workbench.

Needs GTK 3 and libusb-1.0 from your distribution (Debian/Ubuntu: sudo apt install libgtk-3-0 libusb-1.0-0; Fedora: sudo dnf install gtk3 libusb1). Verified on Pop!_OS.

Android

1. Download sightings-android-<version>.apk on the phone and open it. Allow installs from the browser when asked.
2. Connect the DCA75 with a USB OTG cable or adapter.
3. Android offers to open Sightings and asks for USB permission; accept it.

The phone powers the unit over OTG. If the unit's screen does not light, keep its AAA battery fitted or use a powered OTG hub. Only phones with USB host support can install the app.
