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 ,

Thank you for the kind words! I'm happy to hear you like the app. I've noted down your feedback on our Github page for tracking.

Helpful for viewing Certificate details on mobile devices

I can quickly view full certificate details on my iPhone that would normally require me to be at a desktop/laptop PC. This is great for checking things like if any of my site’s Lets Encrypt Certificates automatically renewed.

Very useful to check web site security

The app is super useful to dig into the TLS security parameters of a WEb site, both for debugging as a developer/admin, and to verify a shady web site... The developer is super reactive and welcomes comments and suggestions, which is a plus. Highly recommended!

Developer Response ,

Thank you for the feedback. We've filed a bug to track your request and will investigate making the change in a future release.
