specially designed apps for e-ink-displays

Hi,

I really love my Boox Max! Unfortunately some Apps are drawn in greyscale and animated in a way, a slow e-ink-display can't handle smoothly.

To my surprise Zubersoft released their app "MobileSheetsPro" in a optimised version that they coded in cooperation with Ereader Store.
This version runs fast! No animation! Note-taking is even faster than the built in Onyx note app.

I ask myself, if there are similar e-ink-optimised apps for my Boox Max. Does anyone know them? Is there any E-Ink-Appstore?

Thanks for help!
