See who is on your Wi-Fi.
Netlook scans your Wi-Fi and lists every device that answers, with names, open ports and a guessed type such as printer, TV or camera. Name the ones you know and get an alert when a new one joins.
What Netlook does
A friendly look at your local network, without a router login.
Scans your subnet
Probes your current Wi-Fi subnet (up to a /22, 1022 addresses) with ICMP-style and TCP probes on common ports, with a progress bar.
Finds device names
Names come from reverse DNS, NetBIOS, mDNS / DNS-SD (Google Cast, AirPlay, printers, HomeKit, Spotify Connect, SMB) and UPnP / SSDP.
Guesses the type
Open ports and services hint at what a device is: router, printer, TV or cast device, camera, Apple device, computer and more.
Wi-Fi at a glance
A header shows your SSID, your IP, the gateway and DNS.
Your own labels
Name your devices, mark them as known, see first and last seen, open ports and services, and run a ping test for latency.
New-device alerts
Optional. A background check every 30, 60 or 120 minutes on your saved network tells you when something new joins.
How to use it
Connect to Wi-Fi and look around.
- Connect to the Wi-Fi you want to check, then open Netlook.
- Start a scan. Devices appear as they answer, with names and a guessed type.
- Open a device to name it, mark it as known, see its ports and services, or ping it.
- Turn on alerts in Settings to be told when a device you have not seen before joins.
Honest about the limits
Android restricts what apps can learn about other devices.
No vendor lookup
Android 10+ does not let apps read the ARP table or other devices' MAC addresses, so Netlook cannot show device vendors. Devices are told apart by IP, names and services.
IP is the identity
Because devices are matched by IP address, a DHCP change can make a known device look new.
Types are guesses
A device that does not answer probes or announce a name may stay unlabelled. Scans cover up to a /22 around your phone.
Permissions and privacy
Everything stays on your phone. No account, no analytics. Scan probes go only to devices on your local network, and the only call to the internet is the update check in Settings.
| Network and Wi-Fi state | To read your IP, gateway, DNS and the current subnet. |
|---|---|
| Multicast state | To receive mDNS and UPnP replies from devices that announce themselves. |
| Location | Only to read the Wi-Fi name (SSID), which Android hides without it. Scanning works without it. |
| Notifications | For new-device alerts, if you turn them on. |
| Internet | Needed to open network sockets for scanning and for the update check in Settings. |
