I think we couldn't decide what was best, and we'd wait for user feedback. Well, we got some:
Device: iPhone on iOS 11.3
Thank you for continuing to update your app for iOS.
I have a feature request, if I may please.
With the continued upgrade of Smart Invert on iOS (the closest thing it has to a dark
mode) please could you take a look at making your app more compatible with this feature by
changing the attributes for your Dark and Black Themes so that they stay the same colour
when Smart Invert is activated.
At the moment they revert to a bright white background.
Thank you very much for your consideration,
