The Assembler vs RISC
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
The Assembler
Learn Assembly programming and binary operations by creating pixel art. Each chapter introduces new operations, using 8-bit registers as your canvas to manipulate values and paint an 8x8 image. This app offers a fun, introductory approach to coding fundamentals.
- Learn Assembly programming
- Understand binary operations
- Create pixel art on registers
- Ten chapters with progressive learning
- Interactive 8x8 canvas
- Introduction to programming fundamentals

Learn Assembly programming and binary operations by painting little pixel art pieces. The app teaches different operations in each of the ten chapters. For each of the chapters you program an image with a limited set of commands. Eight rows of 8-Bit Registers turn into your canvas. Use Assembly to manipulate the values in every register, thus creating an 8x8 painting. 'The Assembler' was made as a small and fun introduction to Assembly, Programming and the Binary system that powers it all. The first version of this app was made for the Swift Student Challenge 2022 and won! I hope that you enjoy this project as much as I have.
RISC
Simulate a complete 32-bit mobile system, including CPU units and memory. Write and debug assembly code directly on the simulated hardware to understand its inner workings.
- 32-bit system simulation
- CPU unit simulation
- Memory subsystem simulation
- Native assembly coding
- Built-in debugger
- Hardware analysis

RISC-V Assembly Simulator is a mobile 32-bit system simulator. The app simulates the entire system, all the way from each individual unit on a CPU to the memory subsystem. Write assembly natively to the CPU, with a built-in debugger so you can analyze your code and see what the hardware is doing. This app is designed to allow you to learn how to write assembly from your mobile device, simulating a real CPU at your devices maximum speed. Visualize how the hardware works if you want to, see all the registers, see your entire memory subsystem for each cycle. Learn the components of this individual CPU. This app currently supports the base Int for RV32 along with the M extension, allowing multiplication and division. Dual core systems are supported with the atomic instructions. This app features a built in assembler to allow you to learn to write code along with descriptive errors. Code along with Apple Intelligence, giving you advice and helping you fix bugs along the way (experimental). Natively integrated with your devices file system, allowing seamless transfer between devices and potentially other sources.

Verdict
The clearest difference is update cadence: RISC at every 2 weeks against The Assembler's every 5 months. RISC also leads on review sentiment (100% vs 78%) and rating (5.0 vs 4.8). The Assembler's advantage is ratings volume (10 vs 1) and iOS requirement (17.0 vs 26.0). 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.
RISC holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: The Assembler has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 78% of The Assembler's written reviews are positive against 100% of RISC's.
The Assembler ships an update every 5 months, RISC every 2 weeks. The most recent releases landed on August 17, 2026 and September 14, 2026 respectively.
