Great App to Learn Assembly

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

Pretty Cool

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.
