== History ==
iStumbler was originally based on [[MacStumbler]] source code.{{cn|date=March 2024}} Its early development focused on detection of open wireless (802.11) networks,{{cn|date=March 2024}} but more recent versions support the detection of [[Bluetooth]] [[wireless networking|wireless]] devices and [[Bonjour (software)|Bonjour]] [[network service]]s.<ref name=":2">{{cite book |url=https://books.google.com/books?id=1qxPCwAAQBAJ&pg=PA339 |page=339 |title=Enterprise Mac Security: Mac OS X |first1=Charles |last1=Edge |first2=Daniel |last2=O'Donnell |year=2015 |isbn=9781484217122 |publisher=[[Apress]]}}</ref>

The app has been delisted from the [[Mac App Store]] by the developers due to it not functioning properly on [[macOS Monterey]] and above.<ref>{{Cite web |title=iStumbler |url=https://istumbler.net/labs/ |access-date=2024-03-29 |website=iStumbler Labs |language=en}}</ref>

== Usage ==
iStumbler uses the [[AirPort card]] built into Macs. It automatically scans for [[Wi-Fi]] and [[Wireless LAN|WLAN]] networks,<ref name=":1" /> and can also detect Bluetooth, [[Bonjour (software)|Bonjour]], and other AirPort networks.<ref name=":0" /> The software shows a graph which displays the network name, the type of security, the vendor, the signal, the channel, and the [[MAC address]] of listed networks.<ref name=":3" /> A graph showing the history of signal strength can also be displayed.<ref name=":2" /> It can be used to join listed AirPort networks without configuration and to join Bluetooth networks as well.<ref name=":0" /> It uses GPS data to display the coordinates of the computer being used and nearby Wi-Fi points.<ref name=":4" />

iStumbler works by sending out probe requests to all available access points and displaying the information received from those requests.<ref name=":0" />
