Any Ideas for Free Software Apps?

I have ideas myself, to start off the forum.

Nonfree apps I want Free equivalents of:

1. SUSE Studio
2. Android x86 (in this case Replicant x86)
3. Scratch (but for any GNU programming language)
4. AdVenture Capitalist

EDIT: 5. DeviantArt

There should also be an GNU program that lets people turn binary code into sheet music. You set the parameters, you insert the text (or a chosen binary), and you press play, and then you export the sheet music to MuseScore, PDF, MIDI, etc.

Not sure what you want to use this for, but maybe check out:

Just to be clear, AFAIK the AOSP ("Android Open Source Project" - the Android-Linux core) is already fully free. The non-free parts (excluding the goOgle apps, Maps etc) are the drivers/ firmware required for it to work on some devices. The Replicant project distributes versions of AOSP that can run on a small subset of Android-Linux devices without any non-free drivers/ firmware.

Do Android x86 releases include proprietary drivers/ firmware to allow it to run on as many devices as possible, like Ubuntu etc do? If not, it's already free and no other work is required, otherwise a free fork of Androidx86 would be necessary. It would be necessary to get permission from the Replicant project to use their name though, and it might be less confusing to use another name (eg Hostx86 in reference to Westworld)

I don't understand what you're asking for here. Scratch is a visual programming language, and all the software required to use it is already fully free:
