Its That End User Again ,

An invaluable asset for Users.

This app helped me pin down (no pun intended) the shady certs that were behind the adware problem I have. This problem is so complicated that I’m still gathering data as proof to Apple because I guess they don’t get the whole certificate chain thing... or anything related to http.. or SSL. 😐

So thank you 🙏🏻 to the developers, you guys are doing important work of high quality. This is no crap-app with bad UI, one function, constant ad and analytic network traffic. No, this is a well executed tool, tactful and follows best practices.

My only suggestion is maybe a beginners FAQ or general info page about SSL, Header definitions, etc.

Developer Response ,

Should come with iOS

Great tool that everyone should have installed. Seriously, I don’t know why this isn’t baked into iOS. Everyone should be able to inspect certificates of the sites they visit, and this app adds the feature nicely. You don’t need to switch to the app, either. You can inspect certs of the sites you’re visiting from safari.

Great app. Exactly what I was looking for

I work with websites, DNS and SSL certs every day and this tool provides all of the information I need, quickly, on my cell phone, instead of loading in Chrome or Firefox and trying to find it all. Perfect for my needs. Thanks!
