FAQ

Yes. Scans are free and unlimited, with no account and no ads. The camera check, the security audit, the signal meter, the names file and every other tool are free too. Pro is an optional extra, paid once, and never needed to scan.

Background watch, Bluetooth nearby, the security checks (no password, spoof watch, known flaws and a report), history for good, several networks, Shizuku mode (the maker of every device and blocking an app), a deep port check, deep identify (exact model names), export and a widget. It is one payment on Google Play, with no subscription.

It is part of Pro and it is off until you turn it on. Every 15 minutes, or as often as you set, Netglow checks your Wi-Fi and builds a timeline of who joined and who left. When something new joins, you get a note.

No, and no app on a phone can. The camera check lists devices on your Wi-Fi that answer as a camera or have video stream ports open, and camera hotspots nearby. It cannot see cameras that only record to a card, use mobile data, are wired to something else or sit on another network. Use it as one check among others, for example in a holiday rental.

Since Android 10, apps can no longer read the hardware (MAC) address of other devices. Netglow shows the maker and model when a device tells it, through mDNS, UPnP, NetBIOS or WS-Discovery. Some devices say nothing, and those show as unknown. With the free Shizuku app running, Netglow can read every hardware address again, so makers show for those too.

No. Netglow cannot kick a device off your router. You can block an app on this phone with Firewall, our separate free app, or with Shizuku mode on Android 14 and up. Netglow runs no VPN of its own.

Shizuku is a free app that lets other apps run a few commands with the rights a computer cable has. Shizuku mode is part of Pro. When you run Shizuku and allow Netglow, scans read every device's hardware address, and you can block an app in Android's own firewall. Android drops those blocks on every reboot; Netglow sets them again once Shizuku runs. Everything stays on your phone.

A plain text file with every device, every name it announced and every rename you made. Netglow saves it after each scan and rename, in a folder you pick once. After a reinstall or on a new phone, load it back and your names return.

Android requires location access before an app may read the Wi-Fi name and nearby Wi-Fi networks. Netglow uses it for those two things only. Everything else works if you say no.

Netglow asks devices to announce themselves and checks your own network for weak spots. It never guesses passwords: the no password check only sees whether a device lets anyone in with none. It never reads other devices' traffic. Use it on networks you own or may test.

Ports that should be shut on each device, port forwards your router opened to the internet, how your Wi-Fi is locked, look alike Wi-Fi networks, whether your DNS answers are changed, and whether your secure connections are read in the middle. Each risk comes with a plain fix and counts toward a score out of 100.

No. It listens to what Bluetooth devices around you broadcast anyway, shows them on a radar and warns when a tracker seems to move with you. Nothing it hears leaves your phone.
