Good idea to make it more humane. It should depend on insolation in the current place (it could differ in close locations), or user preferences. I'd prefer to turn automatic dark mode off at all. It would be great if the transition to dark mode be invisible. Like after locking laptop's screen, not in the process of work.

I think it would be more useful to toggle it based on ambient lighting.

Reminds me of f.lux: https://justgetflux.com/

I use Noir extension on my iphone/ipad, does it automatically when iOS/iPadOS goes into night/dark mode (which is also geo-based). Works great on OLED screens!

Most people that I know that prefer dark mode (myself included) prefer it regardless of sunlight or ambient lighting.

Nice! We considered this exact approach but never shipped it in the end. The geolocation permission is probably unnecessary friction and probably an overkill imho... Timezone + rough location (country-level from IP) would get 95% accuracy without the prompt. Most users will bounce on that permission dialog.

Solid work though, especially the twilight transitions. Loving it!!!
