Your listing is costing GED & Me™ installs

Your title leaves half its space unusedTo improve

Length alone wins nothing here. What ranks is the searched term your title carries, and half a title carries far fewer of them, so you turn up on far fewer searches.

Field usage: 9 of 30 characters

Most of your title is not working for searchTo improve

The title is the heaviest ranking field you have, and most of its characters are going to words nobody types on this storefront.

Your short description is barely pulling its weightTo improve

Your short description, the second indexed field, is mostly spent on words with little or no search demand here.

Your short description leaves half its space unusedTo improve

A short short description is not penalised for being short. It simply holds fewer of the terms people search, so it brings you fewer of them.

Field usage: 28 of 80 characters

Most of your screenshot slots are emptyTo improve

Each extra screenshot is another argument, and this is the single biggest gap between your listing and one that fills the space.

On your listing: 6 screenshots

You target terms bigger apps already ownTo improve

Outside your title, several of the terms in your listing are held by apps far bigger than yours, so that space ranks nowhere.
