Does NOT work with iOS 16. Come on devs, put this thing down. ### 1/5 — MITM *2023-01-31, version 1.2.2* The app worked great for a while now the MITM icon is greyed out even though the switch is green indicating it is active. I emailed the developer and after a few days no reply seems they are not interested in responding to paid subscribers. ### 2/5 — Incomplete toturial *2022-05-11, version 1.2.2* The toturial is incomplete it doesn’t tell you how to edit ### 5/5 — Simplicity is good *2021-01-18, version 1.2.2* A perfect utility for checking certificates, not complicated and quick. ### 3/5 — Sort of good *2020-05-16, version 1.2.2* It’s sort of good but it wasn’t what I needed I’m sure it would make good use for other people but this wasn’t what I needed what I needed was to look at the code (console) but it only gives me info about google and not the “console” so I hope people would like this and I hope add the faeture to select items and look at the “console” ### 5/5 — All the info! *2020-03-19, version 1.2.2* Easy to read and all you need. ### 4/5 — not sure *2019-12-04, version 1.2.2* don't know what i was looking for. or if it shows good or bad how do you know what to look for ### 5/5 — great app *2019-11-09, version 1.2.2* does what it needs to quickly and to the point. if you need info on certs this app does the job beautifully. ### 5/5 — Works Great!! *2018-05-04, version 1.2.2* Does what I need and does it well. You pull up the secure certificate for a site, check all the relevant info just like you would in your desktop browser’s debug mode. Wish I would have found this sooner, great app/extension! ## Frequently asked questions about Inspect ### What does Inspect do?
