Very unfortunate because it means you can’t create any loops :( sad because the app looks so nice, and seems like a really thoughtful design. Hoping for an update to fix this issue! Please update soon!?!? ### 3/5 — “Challenging to Use Without Clear Documentation: Three Stars” *2023-04-21* I found this simulator to be somewhat challenging to use, as I was unable to determine which assembly language was being used by the software. Despite my best efforts to locate documentation or reach out to the developer, I was unable to obtain this information. Without a clear understanding of the assembly language being simulated, I found it difficult to use the software to its full potential. Overall, I appreciate the concept behind this simulator, but I would have appreciated more transparency from the developer regarding the assembly language used. It’s possible that other users will have an easier time with this software if they are more familiar with the specific language used, but for me, the lack of clarity made it frustrating to use. ### 4/5 — Branching Operations don’t work *2023-08-16* Hope to see some updates, Please update! Nicely formatted app with pretty good visual appeal to it, but I’ve noticed that the app almost always crashes when using branching operations within the code. ### 5/5 — Cool app *2024-06-23* Please consider open sourcing!!! The community can help maintain and add new features ### 5/5 — Good I guess *2021-09-10* It’s a good app but it needs more controls such as adding a screen and memory for it. The app also needs the ability to write the machine code without asm. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
