[Free with optional Premium]
The app is free to use and shows ads. A one-time Premium purchase removes them.

[Runtime Note]
This is not Visual Studio or Windows.
This app runs on Android and is subject to some of the OS limitations.
Hence Windows-only technologies can't work on Android at all.
This includes WPF UWP Windows Forms the Windows API and all components dependent on them.

Your device requires free storage of at least 1 GB to properly install even though the app takes up only about 350MB.

This app runs a full .NET runtime and compiler on your device so it needs real memory.
- Minimum: 3 GB RAM. Below this the system can easily close the app to reclaim memory.
- Recommended: 6 GB RAM or more and a 2 GHz 8-core CPU. Required for smooth functionality without freezes or the system running out of memory.
Running a MAUI or ASP.NET Core app you have written starts a second process which increases memory use.

[Issues and bug reports note]
Please don't submit bug reports as Google Play reviews as they have response length limits don't support attachments further limiting the posibilities for a bugfix and I will likely never see them. The most robust way to submit a bug report is at the GitHub repository (link at the bottom) however an email to [email protected] is also enough if the data is detailed or unambiguous.

Additional: Because the majority of negative reviews are very vague and almost never respond regardless if asked for more information or told that the bug was fixed I no longer take the considerable time to ever sift through reviews manually.
Instead reviews are classified by AI—either receiving an automated response directing you to GitHub/email or being forwarded directly to my inbox if actionable. Reviews with feedback are forwarded weekly.
