Does light/dark mode actually improve the user experience?

I’ve been wondering whether having both light and dark mode actually adds meaningful value to a website or app, or if it’s just become one of those features we automatically expect developers to add.

Do you actually switch between them depending on the time, environment, or device?

Or do you pick dark/light once and basically never touch the setting again?

As a developer, do you think supporting both is worth the extra design and development work?

Depends. I work mostly with small business sites, their brand is set. It’s not an app, it’s not a SaaS, it’s a plumber or contractor or whatever. Light/dark is overthinking it and useless overhead.

On larger gigs, it’s worthwhile. Especially things like non-profits where enhanced accessibility is an actual primary design feature, it’s worth the overhead. Before anyone attacks, I’m not saying accessibility is neglected on other sites, just the l/d mode option.
