GPS scanning
Detects nearby networks with all their technical data and places them on the map, with a live log of every new network.

ls features/
Everything you need to go out mapping
Made for coverage surveys, authorized audits, research and learning.
Precise location
Each network is placed where the signal was strongest, and moved if a later reading beats it.
Dark map
Networks colored by security type, with filters by session or encryption and search by name or BSSID.
Duplicate-free KML
One KML per session and a global KML with a single entry per BSSID.
Merge with friends
Import WiGLE KML or CSV, even from messaging apps like WhatsApp or Telegram, without repeating networks.
Named sessions
Name, pause and resume your sessions, and search among many when you need to.
ls screenshots/
Terminal aesthetic, end to end
Dark mode with Underc0de’s identity. Tap any screenshot to view it large and move with the arrows. The networks shown are demo data.
man wardrive
From the street to Google Maps in 4 steps
- 01
Start a session
Give it a name (for example, the neighborhood) and keep the screen on while it scans.
- 02
Watch the live map
Each network appears with its security color and is relocated as you get closer.
- 03
Stop and save
When you stop, the session KML is generated and the full KML is updated.
- 04
Share or merge
Upload it to Google My Maps, export CSV for WiGLE or share it with friends to merge.
tail -f wardrive.log
Everything gets logged
While you scan, Wardrive-UC keeps a live log: every new network, every relocation by best signal and the session status. Networks on the map are colored by their encryption.

ls formats/
Your data, in open formats
No proprietary formats: what you capture is yours and you can take it anywhere.
Google My Maps / Earth
One KML per session and a full one. Import it into Google My Maps or open it in Google Earth to see all your networks on a map.
WiGLE 1.4 / 1.6
Export in WiGLE’s standard format to add your captures or cross-reference them with the community’s.
No servers
The data never leaves your phone unless you export a file. No accounts, no cloud and no tracking.
adb install wardrive-uc.apk
Install Wardrive-UC
Free for Android 7 or higher. Scanning requires Android, because iOS does not allow reading the surrounding networks. Get it on Google Play or download the latest APK from GitHub.

Frequently asked questions
Is wardriving legal?
In most countries, detecting that a Wi-Fi network exists —its name, location and security type— is legal, because you only record information the network broadcasts publicly. What is illegal is connecting to or trying to access a network without authorization. Use Wardrive-UC ethically: coverage surveys, authorized audits, research and learning.
Does it work on iPhone?
The app builds for iOS and lets you view the map and import or export files, but it does not scan networks: Apple does not expose the required API. Scanning only works on Android.
Why does it scan every 30 seconds?
Android limits Wi-Fi scans (4 every 2 minutes) to save battery, so the default interval is conservative. If you turn off “Wi-Fi scan throttling” in Developer options, you can scan every 5 seconds.
What data does it store and where does it go?
It stores each network’s public data (SSID, BSSID, channel, band, security and signal) together with its GPS location, all on your phone. There are no servers of our own: the data only leaves if you export a KML or CSV and share it.
How do I merge my map with a friend’s?
Ask them to export their session as KML or CSV and share it with you (WhatsApp, Telegram, etc.). In the app, import it from the data source screen: it merges with your map without repeating networks, with a single entry per BSSID.
Is it open source?
Yes. The code is on GitHub (underc0delabs/wardrive-uc), built with Expo, React Native and TypeScript, with a native Kotlin module. You can read it, build it and contribute.
