Such examples of usage would probably make it easier for a beginner to
think his way into schemespheres. If you could get the right copyright
clearances for any of these applications, please post them. If not,
perhaps the the developers to make the .apk's available, perhaps with a
mention of schemespheres. This could make schemespheres better
known.

Definitely. I'll try to get the copyright clearances, I think is necessary. Otherwise, I plan to make my own tutorials and examples. Everything is still quite alpha, and I prefer few but high-quality examples.
