Show HN: Sift – a minimal news app (looking for UI/UX feedback)

I’ve been working on a small news app called Sift. Looking for honest UI/UX feedback. In screenshots the UI looks clean, but on real devices after installing it feels different — slightly dull / less crisp/ greyish. I can’t figure out if it’s colors, typography, spacing, or something else. Would really appreciate direct feedback on: what feels off or generic anything that reduces the “premium” feel Also not sure if this could be due to display differences or iPhone settings. Blunt feedback is welcome.
