Some apps work very well on Kingrow K1:
- Lightning browser (Settings > Advance > Rendering Mode > High contrast) has very low ghosting compared to default browser
- KOReader (It's possible to install it by F-Droid) has very low ghosting and it's very configurable. Since with the Kingrow K1 it's no possible to force a full refresh (it should be necessary to go to home screen and back to KOReader, but it's break the flow of reading) it's very useful to associate the "night mode" with a specific tab and then it's possible to swicht from normal mode to night mode and going back... in this way it's possible to remove the ghosting if it's necessary
