BirdEcho is a free, open-source Android companion app for existing BirdNET-Pi, BirdNET-Go, and BirdWeather audio detection stations. If you already have a station running, BirdEcho lets you follow it from your phone — no new hardware, no cloud account required.
BirdEcho is not a bird-identification app. It does not listen to audio or identify birds itself. It surfaces what your station has already detected, puts the data in your pocket, and notifies you when a species you care about shows up.

Captured on a Samsung Galaxy S24+ against a BirdNET-Go station. Thanks to @HWittingen for contributing these.
More screens (Species, Stats, Favorites) coming soon — if you're running BirdEcho against your station, we'd love your help! See docs/media/README.md for the capture checklist and how to submit a PR.
- Live detection feed — auto-refreshed every 60 seconds, infinite scroll, pull-to-refresh
- Offline cache — last 24 hours of detections persisted locally; feed is readable with no network, stale data shown instantly while a background refresh runs
- Sighting detail — tap any detection to play the audio recording and share a PNG card
- Detection times shown in your station's local timezone
- Species browser — every species your station has ever detected, with images
- Species detail — detection count, recent sightings list, star/unstar
- Headline stats — detections today, this week, unique species all-time
- 14-day detection bar chart
- Top 10 species by detection count
- CSV export — export the current feed as a
.csvfile from the Stats tab
- Multi-station support — monitor any number of BirdWeather, BirdNET-Go, and BirdNET-Pi stations from one app; switch with a tap from Settings
- Station map — all your BirdWeather stations on an interactive map; tap a marker to switch stations or open in Apple/Google Maps
- Direct BirdNET-Go support — connect over your home network; no BirdWeather account needed
- Direct BirdNET-Pi support — connect to a local BirdNET-Pi instance (both mcguirepr89 and Nachtzuster forks supported)
- Favourites — star any species and get a local notification the first time it's detected each day
- Rare-species alerts — opt-in local notification when a species rarely seen at your station is detected
- Android home-screen widget — today's detection count and last detected species, glanceable without opening the app
- Light / Dark / System theme
- Secure token storage via iOS Keychain / Android Keystore
Android-first. iOS distribution is on hold while the Android app matures (the code stays cross-platform, so local iOS builds remain possible).

See ROADMAP.md for the full, living roadmap.
Android — grab the latest signed APK directly from GitHub Releases.
No Play Store account needed — enable "Install from unknown sources" in Android Settings, download the APK, and install.
Staying up to date — from v0.8.0 onward, BirdEcho checks GitHub Releases on launch and shows an in-app banner when a newer version is available. Tap Download & install and confirm the Android install prompt — no need to revisit this page. (Android requires that confirmation for sideloaded apps; there is no fully silent auto-update without the Play Store.)
iOS — App Store / TestFlight distribution is currently on hold while development focuses on Android. The codebase stays cross-platform, so community builds are welcome — see CONTRIBUTING.md for how to build locally with EAS.
F-Droid submission is in progress.
- Make sure your BirdNET-Pi is reachable from your phone — same Wi-Fi network or VPN.
- Open BirdEcho → Connect your station → choose BirdNET-Pi.
- Enter the host URL, e.g.
http://birdnetpi.localorhttp://192.168.1.50. BirdEcho will probe the station before saving.
Both the original mcguirepr89/BirdNET-Pi and the Nachtzuster fork are supported.
- Make sure your BirdNET-Go instance is reachable from your phone — same Wi-Fi network or VPN.
- Open BirdEcho → Connect your station → choose BirdNET-Go.
- Enter the host URL, e.g.
http://192.168.1.100:8080. BirdEcho will ping the station to verify the connection before saving.
No token or account needed. BirdNET-Go's /api/v2 endpoints are public by default.
- Log in to app.birdweather.com and copy your API token from account settings.
- Find your Station ID on the station dashboard URL:
.../stations/12345. - Open BirdEcho → Connect your station → choose BirdWeather → paste both values → tap Connect.
Your token is stored in the device's secure enclave (iOS Keychain / Android Keystore). It is sent only to the BirdWeather API, never logged or cached in plain text.
Which connection mode should I use? If your BirdNET-Pi or BirdNET-Go instance is on your home network (or reachable via VPN), use the direct mode — no third-party account needed. Use BirdWeather if you share detections publicly or only have a BirdWeather account.
Where do I find my BirdWeather API token and Station ID?
Log in to app.birdweather.com. Your API token is under account settings (top-right menu → Account). Your Station ID is the number at the end of your station's URL — e.g. app.birdweather.com/stations/12345 → Station ID is 12345.
BirdEcho says "No detections found" but my station is running.
- BirdNET-Pi: try opening
http://birdnetpi.localin your phone's browser — if the web UI loads, BirdEcho should connect. Make sure you're on the same Wi-Fi network. - BirdNET-Go: check that
/api/v2/pingis reachable. BirdNET-Go v2.x is required. - BirdWeather: check that BirdWeather integration is enabled on your station. Pull down to refresh after enabling.
The app says "Invalid token or station" on connect. Double-check both values — the token is case-sensitive and the Station ID must be a number, not the station name. Try copying the token fresh from BirdWeather; some browsers add a trailing space.
I connected successfully but the feed is empty. Your station may not have any detections yet. Pull down to refresh. If your station has detections on the BirdWeather website but not in BirdEcho, please open an issue.
Notifications aren't arriving. Check that you granted notification permission when prompted. On Android, also check that battery optimisation isn't killing the app in the background. Note: alerts are local-only (no server-side push yet) and fire while the app polls — when a favourited species is detected, or, if you enable Rare species alerts in Settings, when a species rarely seen at your station shows up.
The Android Map tab says "Map not available in this build."
The Android map needs a Google Maps API key set at build time (EXPO_PUBLIC_GOOGLE_MAPS_API_KEY). Builds compiled without one — including F-Droid/IzzyOnDroid builds — show this fallback instead of the map, because mounting the native map without a key crashes the app. iOS uses Apple Maps and needs no key.
Is my token stored securely?
Yes. BirdEcho uses expo-secure-store, which maps to iOS Keychain and Android Keystore. Your token is never logged, cached to disk in plain text, or sent anywhere other than the BirdWeather API.
Can I monitor multiple stations? Yes — add as many stations as you like (any mix of BirdWeather, BirdNET-Go, and BirdNET-Pi) and switch between them with a tap from the Settings tab.
