Looking for feedback on app design
Hi there!
I've had a pretty square design on most components in my app, which I've been fairly happy with. But when working on a new update, I redesigned one of the pages with (what I think is) a bit more modern rounded design, and I think that also looks very good. Since some of the components of the redesigned page are also used on other pages, it has already started to spread, and I think the app now looks kinda messy, with (at least) two different types of design.
So now I'm unsure. Should I keep the old, square design, should I leave it like it is now, or should I make everything rounded?
I've added some images, with captions explaining what's new and what's old, and some questions. I'm first and foremost looking for advice on whether to keep rounding stuff, or to start reverting the roundedness, but I'm very happy with all feedback!
This is a multi-platform app, so the design should not be too weird on either Android or iOS.
I'm a developer, not a designer in any way, so I feel hopelessly out-of-water when trying to judge these two styles. I think I like the rounded one, but how far should I take it?
Edit: I realise that using "Eversion" as the bookshelf cover image example was a bad choice, since that image has faded edges. Here's an alternative (I was unable to edit the images above, unfortunately): https://imgur.com/a/Qzn5vzi
