One of the best networking device scanners I've used. Easily finds all wired and wireless devices, allows me to nickname them, and shows new devices instantly. I don't even mind the advertisements because the apps function is worth watching them. I don't understand those that say the advertisements make the app irritating to use. I get one add per full scan. I guess some want something for nothing. The app is well worth the advertisements. Of course you can buy the app to remove the advertisements if they are a bother.
Kept getting "network had changed" notifications. Not sure why the app stays active when it's closed. You can just disable the notifications but I uninstalled as don't want any resorses used on a once a month use app. If collected, this data could be worth a lot. A map of where you've been and likely to go. I don't trust it.
