CPU Simulator is intended for students studying A-Level AQA Computer Science, who need to understand certain information on how a computer’s CPU functions. Specifically, the fetch-decode-execute cycle and how components of the processor change at each stage – depending on the code being run. An interactive interface shows the components of the CPU, their contents, a description of what has changed in one clock cycle, an IDE to develop assembly code, an interface to view corresponding machine code, an interface to change preferences and more. Components you can track: • Address Bus • Data Bus • Clock • Program Counter (PC) • Current Instruction Register (CIR) • Memory Address Register (MAR) • Memory Buffer Register (MBR) • 128 General Purpose Registers • Arithmetic Logic Unit (ALU) • Status Register • 128 Data Memory Locations • Instruction Memory Options you can change: • Run Speed (including stepped mode) • Number Base This is a document-based application which means that you can create and run an unlimited number of unique simulations, save and share them. This app is primarily intended to help teach ‘4.7.3.2 The Fetch-Execute cycle and the role of registers within it’ of the AQA A-Level specification, using the Harvard Architecture.

Verdict
The clearest difference is review sentiment: Learn C at 100% against CPU Simulator's 50%. Learn C also leads on rating (5.0 vs 3.6) and iOS requirement (12.0 vs 14.0). CPU Simulator's advantage is ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Learn C holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: CPU Simulator has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Learn C's written reviews are positive against 50% of CPU Simulator's.
