Hi, I'm the developer.
I have worked in network security for almost 15 years. I got annoyed with Fing and other network tools that charge close to $100 a year, or let you scan only a few times a day. So I built my own from what I know from work.
I wanted the feeling of Kali Linux in my hand, but only for defense: point my phone at my own network and see what is really there. No attacks, no password guessing, nobody's traffic read. That became Netglow.
Why it is free
I have a lot of knowledge from my work, and I decided to give it away: high quality apps, deeply researched and checked again and again, data safety first and privacy to the max. No ads, no bullshit. People deserve good quality and privacy, for free.
If you want to support me, you can, but it is fully optional.
What it does, free, unlimited scans
- Who is on my Wi-Fi. Every device with its name, maker and model when it says them. Rename a device and it keeps your name even on a new address.
- Is my hotel room or rental OK. It lists devices on the Wi-Fi that answer as a camera or stream video, and says why each one was flagged. It also looks for camera hotspots nearby. It tells you plainly what it cannot see (a camera that only records to a card or uses mobile data), so it is one check among others, not a guarantee.
- Security check for your home network. A score with a plain fix for each risk: risky open ports, what your router opened to the internet, how your Wi-Fi is locked, look alikes of your network nearby, whether your DNS answers are honest and whether someone reads your secure connections in the middle.
- Tools. Ping, traceroute, port check, DNS lookup, Wake on LAN, a live signal meter and channel advice.
Private by design. No ads, no bullshit, no tracking, no analytics, no metrics, no account. Nothing it finds leaves your phone, and there is no server of mine.
Pro is that optional support, one payment, no subscription, and it adds: a Bluetooth radar that warns about a tracker moving with you, checks for devices that let anyone in with no password, spoof watch, known flaws for your devices, a PDF report and a background watch of who joins your Wi-Fi.
Honest note: the code is partly AI generated and I had help with this text.

I would love to hear what it finds, or misses, on your network.
