Show me what connects me
WIFI is inherently invisible and with this hard to grasp. Minimal information provided by MacOS or professional tools that are diffciult to navigate both don’t offfer a viable solution to navigate wireless connections for amateurs with a reasonable half-knowledge.
I have used many versions of iStumbler over the years to resolve WIFI issues and this is finally an Apple-approved version. Well worth the money if you use wireless connections.
I was a bit intimidated as to what a tool like this would require from me in terms of learning curve etc. Very easy to use, poweful. Impressed by all the information that it provides.
Great app! Thanks for making it, I noticed when trying to switch maps that it doesn’t switch.

Hey DOS486 (Great Username!),
Thanks so much for the review. I've patched a bug which disabled the Location plugin, the update will be live on the store any moment. Should resolve the Maps pull-down not working and will show you the estimated locations of local Wi-Fi networks and Bluetooth devices.
With Family Sharing set up, up to six family members can use this app.
