Sorta…? Like, the outdated part is the visual, but the rest of the app is mostly fine, so you can spin the outdated visual as being minimalist or something like that. If you just updated the components to Material Design 3 it would be functional and fine.
The same couldn’t be said for Tasker for instance, which is outdated in general, and just updating the components wouldn’t fix much of the issues it currently has with the UX.
