A solo developer's toolbox, without the SaaS bill
App Store Optimization is the foundation of organic growth for any mobile app. The work breaks down into a handful of concrete tasks: counting characters, validating against store rules, drafting copy, and previewing how a listing will look before you ship it.
Each of these tasks doesn't justify a paid subscription on its own. Together, they do. So we split them into discrete, single-purpose utilities you can open in a browser, use once, and close. No account, no trial, no upsell wall.
Pre-flight every field
Catch character overflows, missing screenshots, and rejection-triggering claims before the submit button.
Skip the spreadsheet
Reference tables for icons, screenshots, and store limits. No more screenshots-of-screenshots from Stack Overflow.
Draft, don't blank-page
Title, description, and release-note templates by category. Start from a proven shape, not a blinking cursor.
