Go buy it. Just buy it and come back for the review.
I hope you’re reading this after you bought it! I’m one of those “I don’t write reviews” kind of guys, unless something really impacts me in a meaningful and worth-while way to express my endorsement on a product. Even being a random stranger on the internet, I still try to be honest. I bought this app sometime around 2017-2018 while I was a Systems Administrator intern for a manufacturing company. This app has since become my networking multi-tool and it has had a main place on a Home Screen for years. It does pretty much anything you need for networking diagnostic, quick scanning, mac address lookups, FTP, SSH, and so much more. My butt has been saved many times by this app, having a quick multi-tool I can hop around on, poking and prodding to troubleshoot. The interface isn’t the most intuitive at first, but it’s super functional. My only request to the dev team is don’t “prettify” your UI. As an exhausted Network Administrator, I need at least one tool that aims to provide function and not form. I think back to the days of being a child and asking my father about all the tools in his toolbox. It was a mess, but he knew what everything was and where it went. This is my toolbox :) I love this app because it just works, and there’s very little descriptions or hand-holding or user-friendly nonsense. You must know what the tool is you’re using, how to use it and how it works. That’s the absolute best thing I can say. I’d give it more than 5 stars if I could.
