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.

Duo Update!
A truly amazing calculator app that’s constantly updated has everything you could ever think of AND it just got one of the best Duo updates. What a joy to use!

PCalc is the the best!
An amazing product from a passionate dev. One ask, please bring back the checkered pattern icon for 1992. Nothing wrong with the new one but the original has been a staple of my home screen since as far back as January 2020.

Internal purchase problem
I think the application itself is a paid application. It is very unreasonable to pay money to unlock the icons in the settings. As a paid application, the icons in the application need to be unlocked for an additional fee. I really don't understand why this is so.
