App still slow and glitchy on iOS after removing problematic components and optimizing screens

Hi everyone,

I’m still facing serious performance issues in my app and I really need help identifying the root cause.

Current problems:

  • slow list loading

  • laggy and choppy navigation

  • glitches during screen transitions

  • overall very poor smoothness and responsiveness

This is happening in the iOS build on my iPhone 15,4.

What I already did:

  • removed the paid Audio Player List component because it was causing bugs and crashes

  • removed the Video Component because it also seemed to create instability and crashes

  • optimized heavy screens after following Xray recommendations

  • reduced the number of components on the screens that were flagged as too heavy

  • identified a paid Gradient Rectangle component that appears to glitch visually during screen transitions

Regarding the Gradient Rectangle component: I already tested all possible combinations of sticky settings, anchoring, and width resizing, but the glitch still remains during screen changes.

So even after removing unstable components and optimizing the heavier screens, I am still seeing:

  • slow and hapering loading

  • bad performance when navigating

  • glitches between screens

  • an overall sluggish experience throughout the app

At this point, it feels like the issue goes deeper than just heavy screens. I would really appreciate it if someone could thoroughly review what may be causing this, because the app is currently not smooth enough for release.

I’ve spent a lot of time troubleshooting this from my side, but the app is still too slow and unstable for launch. I would really appreciate a deeper technical review from the team.

Here are two videos I made to illustrate the glitching issue.

Thanks in advance.
