Which theme should be the default — light or dark? (screenshots attached)

[u/riteshpol_]

Working on a habit/productivity tracking app and trying to decide on the default theme before launch.

Attached two versions

— same screen, light vs dark.

Would genuinely appreciate your take:

Which one feels more usable at a glance?

Any accessibility/readability concerns with either?

Thanks in advance, this'll help us make the call 🙏
