5/52025 UPDATE! Must Have essential security aid for iOS 🔐
2025 UPDATE: It's been at least 10 (!) years since I've been using this app. Times have changed since then (And thankfully, server configurations) It remains unmatched in purpose, functionality, stability, and expertise. Recently there was a massive implementation of something NO OTHER APP does; device CA root certificate updating. Yup, it peeks where no other app dares- Except pretty shady ones. I trust this developer, and appreciate the thought and coding needed to get there. 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. 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.

5/5Essential tech utility
I’ve been using TLS Inspector for years now. Part of my job is managing cert renewals and other security related components for company resources. I use TLS inspector to help validate certificates, including making sure the correct cert is being served and expiration times, etc. from public internet on my phone. This app does exactly what I need with no fluff or bloat and without drowning me in ads. I consider it an essential tool in my tool belt. Highly recommend.

5/5Amazing
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issues this website having (like “dollar general” store, a website legit but their security protection is a bit outdated).

5/5Awesome 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!

2.5.2
Thanks for using TLS Inspector! • Updates OpenSSL to 3.0.7 to address high severity security vulnerability. This update also applies to iOS 9, 10, and 11 devices as well. There will be no further updates to the app on those devices going forward. For real this time.
-
2.5.3
Thanks for using TLS Inspector! • Updates OpenSSL to 3.0.8 to address a vulnerability with certificate and CRL validation
-
2.6.0
Thanks for using TLS Inspector! This release includes a major new change in how the app builds certificate chains and determines trust. TLS Inspector now includes root CA certificate bundles from Apple, Google, Microsoft, and Mozilla. These bundles cannot be modified by configuration profiles and allow the app greater insight into the trustworthiness of a root certificate. Think of it like asking 4 other doctors for a second opinion. These bundles are embedded in the app itself but can also be manually updated from within the Advanced Settings page. These bundles are hosted on GitHub and are digitally signed. Furthermore, keeping in line with changes to trust, we have changed the behaviour of how the app deals with locally trusted certificates. The wording and appearance of the trust banner and information have been altered to highlight the risk these certificates pose. You can revert to the previous behaviour by enabling "Treat Unrecognized Certificates as Trusted" in the app's options. And if you thought that was all then you're wrong and you owe me an apology: • Added support for viewing signed certificate timestamps both embedded in certificates and in the handshake. • Moved the link to view subject alternate names to the subject section. • Fixed a bug where the keying material table would show up randomly. • Replaced the Twitter link with Mastodon, because, well, yeah.
-
2.6.1
Thanks for using TLS Inspector! Nothing all too special with this release, just addressing some issues found with the last update. • Improved privacy when updating root CA certificate bundles (requests are now proxied through tlsinspector.com rather than directly to Github) • Improved handling of cross-signed certificates for vendor trust status • Improved HTTP header logic and presentation • Big ol' batch of fixes from static analysis • Fixed a bug where images or links wouldn't load because we weren't paying ourselves for our own API
-
2.6.2
Thanks for using TLS Inspector! We've added 4 new app icons that you can pick from to customize the look of TLS Inspector. You can access these in the app's options. Also: • Fixed a bug where the unrecognized certificate trust banner was unreadable on light displays. • Reduced the app size by around 20% • Updated to OpenSSL 3.1.0 • Updated to curl 8.0.1
-
2.6.3
¡Hola! TLS Inspector is now available in Spanish! Thanks to Kevin López Brante for providing the translation. Also: • Minor UI improvements for iPad users
-
2.6.4
Hallo! TLS Inspector is now available in Dutch, thanks to a generous contribution from Erik van Straten. Also: Spanish translation should actually work this time! I totally 100% didn't forget to include the translation files. Nope. Didn't forget.
-
2.6.5
Thanks for using TLS Inspector! • Update OpenSSL to 3.1.1 • Update curl to 8.1.2 • Enforce strict content-type on CRL and OCSP response • Enforce maximum content length on OCSP response • Improvements to verbose logging
-
2.6.6
Thanks for using TLS Inspector! • Fixed a crash caused by certificates that have a non-URI CRL distribution point entry • Cleaned up the boxes of top-secret documents in our bathroom, moved them to the laundry room instead.
-
2.7.0
Thanks for using TLS Inspector! If everything has gone right, you shouldn't notice anything different with the app. We took this time to make some much needed improvements to the inspection logic of the application, which should result in faster results, less crashes, and support for a wider set of TLS servers. If you're interested in learning more about these changes, you can read more on our Mastodon account - linked in the About view of the app. It's not all boring backend fixes, however - we've also: • Added an option to specify the language for the app, overriding the system language • Added a button to reset advanced settings to their default values
-
2.7.1
Thanks for using TLS Inspector! • Fixes a bug where re-inspecting a recent lookup would fail
-
2.7.2
Thanks for using TLS Inspector! • Updated curl to 8.3.0
-
2.7.3
Thanks for using TLS Inspector! • Updates curl to 8.4.0 • Fixes a bug where certificate expiry reminders couldn't be added on iOS 17
-
2.7.4
Thanks for using TLS Inspector! • Update curl to 8.5.0 • Update OpenSSL to 3.2.0 • Moved Open Source Licenses & Attributions from the settings app into the about screen
-
2.7.5
Thanks for using TLS Inspector! Due to the complexity of supporting it, we're deprecating the legacy Apple network engine (based on SecureTransport). In the next major update, TLS Inspector will remove this engine entirely, and users will automatically be migrated to the modern Apple network engine (based on the Network framework). OpenSSL remains supported. • Show extra extensions on certificates. Supports strings, booleans, integers, and dates. • Added warning about upcoming deprecation of legacy Apple network engine. • Improved messaging for when a HTTPS proxy is enabled. • Some very minor UI polish. • Fixed a bug where a passenger door could come off unexpectedly.
-
2.8.0
Thanks for using TLS Inspector! • Added some fancy schmancy new icons! • Normalized font sizes across the entire app, also fixed dynamic font sizes not working within the app • Removed the legacy Apple network engine • Fixed an issue where an untrusted certificate might mistakenly be labelled as using SHA1 • Added a link to my other app, DNS Inspector, in the about view. Speaking of which... If you like TLS Inspector you may be interested in my newest app, DNS Inspector! Following the same core principals of TLS Inspector, DNS Inspector aims to help you better understand the complexities of DNS name resolution.
-
2.8.1
Thanks for using TLS Inspector! • Fixed a localization issue with recently inspected hosts • Fixed an issue with the inspect certificate extension on macOS • Made just the slightest tweak to the icon • Updated OpenSSL to 3.3.2 • Updated Curl to 8.9.1 This will be the final update that supports iOS 12 to 14 (inclusive). The next release of TLS Inspector will require iOS 15.6 or newer, which means that the following devices will no longer be supported: iPhone 5s, 6, 6 Plus, and iPad Air 1, Mini 2, Mini 3. TLS Inspector will continue to function on unsupported devices, however as the device ages root certificates will eventually expire and this will generate trust errors.
-
2.8.2
Happy new year! While we do have a major update planned for later in the year, right now we're just keeping things running smoothly with this small update. • Add dark & tinted icons for iOS 18 users • Fix the App Icon selector not showing previews after iOS 18 • Update curl to 8.11.1
-
2.8.3
Thanks for using TLS Inspector! • Fixes a bug where not all HTTP headers were collected during inspection in some circumstances
-
2.8.4
• This update removes the ability to send an email with feedback about the app. To report an issue with the app or to request a feature, please use Github, or reach us on Mastodon or Bluesky.

3.0.0
Welcome to TLS Inspector 3.0 - the largest update yet, released on the 10th anniversary of our first release. TLS Inspector 3.0 is the culmination of over a year of hard work to modernize nearly every aspect of the app while maintaining the same behaviour you've come to rely on. Here are some key highlights: • SwiftUI Experience. The user interface of the app has been modernized by utilizing SwiftUI, providing you with a more consistent design with improved accessibility features. • More Data. This update includes more information with your inspections, including certificate sources, results from status checks, and improved handling of certificates without subjects. • Swift-Powered Inspection Engine. The inspection engine is what provides the information you see when you perform an inspection. With update 3, we've completely redone this engine to use Swift - providing you with a more stable and faster inspection experience.
