### 5/5 — Amazing!

*2026-07-10*

A brilliant game! I’d really love to see more challenges. :-)

### 5/5 — Super cool

*2026-04-11*

Love it. Totally fun. I just wish there were more challenges. More commands would be great also!

### 5/5 — Super cool

*2026-02-18*

Love it. Totally fun. I just wish there were more challenges. More would be great also!

### 5/5 — Great App to Learn Assembly

*2026-02-14*

A nicely put together learning curriculum that tests your knowledge as you progress. This feels like a game. Perfect!

### 5/5 — Pretty Cool

*2025-09-07*

I really enjoy stuff like this, reminds me of a zachlike game.

The app is well made and intuitive, at least for me. However, there are a few points of contention I’ll just mention in the spirit of full transparency:

1. I’m sort of disappointed there isn’t a way to store programs or code snippets locally in the app, or even the ability to export a program to the file manager. Sure, you can just copy and paste, and I guess that’s sufficient because:

2. I’m don’t really expect to be spending much time in the app now that I’ve completed all the challenges. Granted, it did take 3 or 4 hours to do so from start to finish, but once the challenges are complete, the real challenge becomes coming up with a reason to stay in the app. This means that:

3. I’m finding it difficult to figure out any justification for the monthly subscription plan. Perhaps if there were a community of users uploading custom challenges to download, or any sort new content each month, or integration with leetcode or something, maybe it would make sense. I just don’t see there being enough users to warrant such a thing. That’s why I decided to just get lifetime pro just to support the dev.

### 5/5 — Excellent!

*2025-08-11*

You did a great job!

### 5/5 — Learning through solving

*2025-05-20*

Introduces the principles and quickly moves to exercises. Good fun for making the time pass. Won’t make you an Asm developer but will give you a good appreciation as solving problems that are normally handled by a function, but no For or Do While loops and making it nice to appreciate the steps required.

### 5/5 — A hidden gem!

*2025-05-10*

I am teaching myself programming, and, on a lark, I did a search for an app to practice assembly. This one is perfect. The learning process is made into a game which makes it much less tedious to get through the lessons, and you benefit by getting  hands-on experience right away. I highly recommend this app
no matter what language(s) you plan on learning; the carry over is well worth the investment.

### 3/5 — Not “real” assembler

*2025-04-19*

I love the concept, but sadly the language is not “real” assembler and doesn’t teach very useful assembler. MOD? PRINT??!

### 5/5 — Back to the good old days

*2024-11-16*

What an excellent idea for an app and what an excellent execution!
My only “criticism” lies with the CPU I used to work with, back in the eighties, having fewer registers and a much reduced set of commands 😎. Other than that misalignment with my own personal experience, this app is an excellent reminder for how we used to do things and a great lesson on how, way down inside, computers work.
I will also credit the app for its absolute respect of my privacy. Far from common these days, I’m afraid.

**Developer response:** We’re glad you enjoyed the app, and agree wholeheartedly about user privacy!
