Same here, that's why I sometimes wish I had saved some screenshots for my own use or even for sharing but I have a feeling Apple would have hunted me down for it. That's probably why we don't see so many of them in the wild. Even in the orientation you'll hear stories about how seriously they take their ability to surprise and delight, with an emphasis on the surprise. :)

The best source I can find was this: https://www.theiphonewiki.com/wiki/Apple_Internal_Apps

With this fascinating discussion of Apple insiders talking about exactly the same apprehension imprinted in their minds: https://www.theiphonewiki.com/wiki/Talk:Apple_Internal_Apps

Here are some things I remember:

The "purple" series of tools are basically for managing dev-fused iPhones https://www.betaarchive.com/imageupload/2017-02/1487521492.o...

I also remember there being two internal wikis for development and having access to both. Maybe one is called luna and the other is just straight out called purple?

You get root on the device simply by authenticating as root with password alpine. Sometimes you'll get your hands on iDevices with weird specs like 3.75GB of RAM etc.

There is also AppleConnect which is Apple's internal single-sign on.

What I find fascinating the most is honestly how I am unable to find recent screenshots of these software. They are all screenshots of really old versions with outdated UI.

Apple must have a special way of taking these down or doing offensive-SEO and burying them in results because while I was able to find search results for "apple luna internal wiki", I am no longer able to.

I loved PurpleRestore and never would have wanted to go back to the iTunes way of managing my device.
