Not working like it used to. – WUMW: Who uses my WiFi? Review

I used to love this app. When it was free it worked.. I don’t mind the colors (though I prefer the old design) but I can no longer rename devices in the WUMW list. When I click on each them the same is shown. Then I edit the text but it’s doesn’t appear to be renaming the device like I used to be able to so I can more easily identify devices on my network. App developers, please look into this when you can for the next release. Also pulling down on the table view no longer refreshes. As an app developer myself I wish I could jump in and help fix these things.
