Via OTRS:
A feature that would be very welcome in the iOS: allowing change between day/night mode (light/dark background in-app) via brightness. An app called Apollo for Reddit currently uses this feature to allow switching from light/dark mode. It also doesn’t require location data to be given, like many other apps try to get from users, as it solely uses your device to measure it.
Maybe add a theme preference for "Theme when brightness is below 25%: " so users select sepia or either dark theme
