A macOS menu bar app for monitoring your ADS-B stations.
Supports FR24, readsb/dump1090, Planefinder, and Airplanes.Live.

• Live aircraft count, messages/sec, and signal strength in the menu bar
• Choose what to display in the menu bar (aircraft, msgs/sec, signal, max range)
• Multi-station support with per-device detail view
• Auto-discovery via local network scan (scans your /24 subnet for all station types)
• Max range calculation via Haversine formula (requires receiver coordinates)
• Signal quality indicators with color-coded thresholds
• Notifications when a station goes offline
• Configurable distance units (km, miles, nautical miles)
• Custom receiver location as fallback for range calculation
• Editable Web UI path per station
• Open station web interface or feed status directly from the menu bar
• Local station types stay on your network; Airplanes.Live connects to their public API

FR24 stations also pull data from tar1090 (/tar1090/data/stats.json and /tar1090/data/aircraft.json) when available, giving you signal stats and max range even on FR24-only setups.

Planefinder stations also fetch aircraft data from /ajax/aircraft for aircraft count and max range calculation.

Airplanes.Live connects to the external API at api.airplanes.live and shows feed status, MLAT peers, bandwidth, RTT, and nearby aircraft count. No API key required.

Homebrew:

brew install --cask ciruz/tap/adsbar

Manual:

1. Download the latest .zip from Releases
2. Unzip and move ADSBar.app to /Applications
3. Open normally, the app is signed and notarized

• Local Network Access - required to reach your stations over the LAN. Without this, nothing works.
• Notifications (optional) - alerts when a station goes offline.

Network Scan: Click Scan Network in the popover. ADSBar scans your /24 subnet for FR24, readsb, and Planefinder stations automatically. Airplanes.Live must be added manually since it's an external service.

Manual: Click Add Station... and select the station type, name, IP address, and port. The port auto-fills based on the selected type.

Custom Location: If your receiver doesn't expose coordinates via receiver.json, you can enter latitude and longitude manually in the add/edit form. This enables max range calculation.

Polling interval (5s - 60s), distance unit (km/miles/NM), launch at login, status bar toggles, and notification preferences are in Settings... in the popover.

The menu bar shows a plane icon with your station stats:

✈ 33 | 524/s | -13.0 dBFS

Each value can be toggled on or off in Settings. Click to open the popover with per-station details including aircraft count, ADS-B split, messages, signal, noise, max range, feed status, and more.

Requires macOS 14.0+ and Xcode.

git clone https://github.com/ciruz/adsbar.git
