Details
IRIS OS Applesauce is the operating system that You, Teddy's, and Anna's (and probably most characters in the first part and spinoff of SIMULACRA) phones run on, While OS 13 is Maya's Operating System

In order to stop the phone reset, The Player must know what the IRIS OS Version name is. After the inevitable phone reset, IRIS OS reboots and asks The Player questions such as "What is your full name?", "Where do you live?", and, "If you looked behind you right now, would you rather see a floating disembodied head or a headless body". Even asking The Player to surrender all personal data to the IRIS operating system. If you don't surrender all personal data, IRIS OS Setup replies "Too bad for Anna then".

Easter Eggs
When the IRIS OS Setup asks for your name in SIMULACRA, you can tell it:

Name Reveals

 * Markiplier - It will say Mark Fischbach
 * Jacksepticeye - It will say Seán William McLoughlin
 * Game Grumps - It will say Arin Hanson
 * Harshlycritical - It will say John Wolfe

Errors

 * Anna/Anna Hardy - It will say "I asked for YOUR name."
 * Toby/Tobias - It will say "Toby, is the cat. I ASKED FOR YOUR NAME!"
 * Simulacra/Simulacrum - It will say "It is not you, and you are not it."
 * Inputting a swear word will read "No cussing, you ASSHOLE!"
 * Inputting anything more than 5-6 words or numbers will read "This cannot be a name!"
 * IRIS - It will say "I ASKED FOR YOUR NAME!"
 * Greg/Greg Summers - It will say "You are not Greg. I ASKED FOR YOUR NAME!"
 * Ashley - It will say "You are not Ashley. I ASKED FOR YOUR NAME!"

In "SIMULACRA: Pipe Dreams"
IRIS OS Applesauce is the OS on your (UserCruiser) phone and it is out of date. Among all mini games in SIMULACRA: Pipe Dreams, you can only play the game "Flapee Bird". When clicking/tapping on other games, it will trigger a pop up window saying that your OS is Outdated and Unsupported and "If you want to update, please visit our store."

In "SIMULACRA 2"
IRIS OS 13 is also installed on Maya's phone in SIMULACRA 2. The app "WARDEN" will turn the "IRIS Memo" Button (in the lower right corner) into a scan button when evidence is visible. The police department's casefile system is also supported by IRIS OS, through the WARDEN app.
