visible word pool · 4 words
title 5/30 chars · subtitle 19/30 chars
App Store search indexes the title and subtitle together with the hidden 100-character keyword field as one combined pool: any phrase assembled from those words can rank. These are the words of PCalc's pool that are public — the keyword field is not exposed by any API.

Too hard to read
PCalc is powerful, but the UI is a mess. Themes are bright and distracting, and there’s no way to get simple high-contrast text across the keypad, tape, and buttons. Fix one area and another becomes unreadable. Basic readability shouldn’t be this hard.
