An unofficial iOS client for WatchYourLAN

See every device on your network, from your pocket.

LANtern talks directly to your own WatchYourLAN server and allows you to access all your devices using a clean iOS native interface.

Built for the list you already check

Nothing here you have to configure twice.

Live status

Every device shows online or offline, refreshed periodically within the app.

Search & sort

Find anything by name, IP, or vendor, no matter how many devices you own.

Multiple servers

Switch between home, a friend's lab, or the office without losing your place.

No background polling

LANtern only checks in while it's open. Your server's own notifications handle the rest, and your battery will thank you.

Self-hosted, by design

You run the server, LANtern does the rest.

Point LANtern at your WatchYourLAN instance's address and it starts reading straight from it. If it can reach it, it can read it. If you ever take your server offline, LANtern has nothing left to show.

LANtern is an independent project and isn't affiliated with the WatchYourLAN maintainers. WatchYourLAN itself is open-source: see the project on GitHub.

What LANtern collects

Nothing. LANtern doesn't operate any backend of its own, so there's no server for your data to pass through on its way anywhere. The app includes no analytics, no tracking, and no crash-reporting SDKs.

What's stored on your device

The address of any WatchYourLAN server you add, the optional HTTP Basic Auth credentials and whether you've chosen to trust a self-signed certificate for it, are saved locally on your device so you don't have to re-enter them. That information stays on your device and is only ever sent to the server address you configured.

Local network access

LANtern asks for the Local Network permission because it connects directly to your WatchYourLAN server over your home network or VPN. It's used solely to reach the address you've provided. Nothing is scanned or accessed beyond that.

Data from your own server

Device names, IP and MAC addresses, vendor info, and history shown in the app come from your own WatchYourLAN instance. That data is generated and retained by your server, under whatever configuration you've set there.

Third parties

LANtern doesn't share data with any third party, because it doesn't collect any to share.

Changes

If this changes, this page will change with it, and the date above will reflect that.

Support

Something not working, or a feature you wish existed? Email is the fastest way to reach me.

LANtern can't reach my server

Confirm your phone is on the same network or VPN as your WatchYourLAN server, and that the URL includes the right scheme (http:// or https://) and port. If your server uses a self-signed certificate, enable "Trust Insecure SSL" when adding it.

No devices are showing up

LANtern only displays what your WatchYourLAN server has already scanned. Check that your server's scan interval has run recently and that its configured interface is picking up your network.

Does LANtern work without WatchYourLAN?

No. LANtern is a client, not a scanner itself. You'll need a running WatchYourLAN instance to connect it to.
