UPDATED!🔏Must Have essential security aid for iOS
UPDATE: Still going strong, thanks to this app over the years I’ve been able to learn about cert chains in the Apple server environment on device!
I downloaded This tool years ago and it’s been on all my devices- testing and personal- as an essential web tool, especially these days with web apps being everywhere. It’s helped me trace down all sorts of inconsistencies, unexpected behavior, and hands down shady stuff… all through the iOS share sheet! From simple double checks out of safety, to hunting down a rotten CA issue this app never fails. Thank you to the dev for keeping it updated and for designing such a great tool. Wish I wrote this 4 years ago when I starting using this! UPDATE: It’s been a few years and this app has grown to something better than I ever expected. This dev KNOWS certs. I mean, really knows. This isn’t just some easily coded generic utility tool app. You won’t find any other cert apps anywhere near as advanced as this.
Would have been six stars
I wanted to add an extra star for fixing the bug where the passenger door kept falling off.
Great app but get error messages lately.
This is a great app the allows you to view a website’s security certificate and I think this ability should be built in to safari but for some reason it’s not. But lately every time I try to check for certificate bundle updates I get the error message “failed to securely check for TLS bundle updates please check for pending updates for TLS inspector in the AppStore.” but currently their are no app updates available on the AppStore so I really hope this issue is fixed soon.
Clever implementation tool for iOS
I lived too long without a direct cert tool. This was the answer. TLS 1.3 support pushed this over the top. Outstanding ease of use and small footprint. Others would do well to take notice of this developer.

Amazing
Using “Google” chrome browser which sometimes a “Website” have a warning Icon on my “address” which technically says the website Protection “outdated”…This “app” on the other helps me check out (inform) what “security” issues this website having (like “dollar general” store, a website legit but their security protection is a bit outdated).
Fantastic
I'd been battling some issues with SSL server certs working on Windows but not on IOS. Apples messages were totally useless in diagnosing. This tool on the other hand instantly diagnoses the issues.
App freezes
Today I just got an update. I used nytimes.com to share certificate chain. The app froze.
A Must Have; essential security aid for iOS that I’ve used for years!

Awesome to begin with and awesome in continuing development
A very useful tool. Developer could have stopped working on it long ago but not only corrected and added things, but also applies updates when technology, methods, and practices change over time. Keep up the good work!
