Your screenshots are in the wrong order, and the file names prove it.
Apple serves your first slot from a file called 04.png and your fourth slot from 01.png. Somewhere in the upload the set got reversed, and the running order that reaches a browsing golfer is exactly backwards.
Frame 4, the one almost nobody reaches, is the one that explains the product. "Golf Scorecard" over "Golf, Mini golf, Disc golf" answers the only question a browsing golfer has, which is whether this works for the game they actually play, and the screen underneath shows a shelf of finished rounds at Augusta, Highlands Disc Golf, Legends Putt-Putt and Oakmont, each with a date and a winner. That is the picture that sells a scorecard app: proof that people finish rounds in it.
Frame 1, the one everybody sees, is the Edit Scorecard settings sheet under the word "Customizable". Both halves work against you. "Customizable" names a property rather than a promise, and a settings form is the part of any app nobody looks forward to. There is a second cost hiding in it: the example course loaded into that form is Highlands Disc Golf. Your app is called Golf and Mini-Golf Scorecard, and neither golf nor mini golf appears anywhere in the first image a customer sees.
Reversing the four frames costs nothing and needs no new artwork. Put the shelf of rounds first, the finished eighteen hole card second, the one tap scoring row third, and the settings sheet last if it stays at all.
Two smaller things. You are using 4 of the 10 slots Apple allows. And in frame 2 the scoring row occupies the top third of the screen while the bottom half is empty black, so the frame gives away height it could have spent showing the hole and the running total together.
