Great App, Good Job Guys... Friendly User Tip: Don't be to hasty in blocking they just gave you unconditional access ? how nice of them. First limit their access permissions & speed. Second have Fun, All you have to do is look for a few code snippets & send them a packet or two before blocking them . Ps. Remember Change your router login and password as anyone you block only needs to spoof their MAC/IP and gain access again. Turn ? your AP name broadcast too so they need find the right guess
(Works as it says. thank you.) ATTENTION! This was my first opinion but after I buy the pro version and the app says there is people on my wi fi, THAT WAS A LIE! I didn't trust it in first place because they asking for the wifi password and them they said you can change it later OHH YEAA! yes after they have the main password it can be configured you as a guess and you do not notice, don't believe me read the comments and you will understand what happens after you given your router password,
So far, so good. Found all my devices first try. Seems to do what it's supposed to do. Update 11/2/19 don't like the way the app constantly requires closing. With wifi on, app is constantly working in background unnecessary telling user connected devices already listed as "known." I ONLY want to know any changes such as NEW connections or attempts to connect. 4/25/20 they obviously don't read reviews. App refuses to close. Gonna uninstall. 8/18/20 reinstalled. Issues seem to have been addressed,
