ASO Listing Checker: Google Play and App Store limits

What does ASO Listing Checker do?

It checks your Google Play and App Store listings, in every language, before you upload them, and returns one row per listing:

• Character limits per field: Google Play title 30, short description 80, full description 4,000; App Store name 30, subtitle 30, keywords 100, promotional text 170, description 4,000, What's New 4,000. Each field gets its length, its limit, the characters left and its UTF-8 byte size.
• App Store keyword field audit: spaces after commas, words already indexed from the name or subtitle, repeated words, stop words, and the total number of characters you can win back for new keywords.
• Name and subtitle overlap on the App Store (each word is indexed once).
• Policy warnings: promotional terms in a Google Play title or short description ("best", "#1", "free", "top"...), emojis in the app name, titles in capitals only.
• Keyword density of the full description (top 10 terms), with a warning above 3 % on Google Play.
• Live App Store reading: give App Store IDs or bundle IDs and countries, and the public name, description and release notes are read from each storefront and checked.

Who is it for?

Indie developers, ASO consultants and localization agencies who ship listings in 10 to 40 languages and want to catch the field that is 3 characters too long before the console rejects it, or the keyword field that wastes 15 characters on repeats.

How much does it cost?

Pay per event: one event per listing checked (one store, one language). Rows with an error (app not found in a storefront) are not charged. Use Max listings as a spending cap.

Input example

{
  "listings": [
    { "store": "play", "locale": "de-DE", "title": "Gewohnheiten Tracker: Tägliche Ziele", "shortDescription": "Baue Gewohnheiten auf, die bleiben." },
    { "store": "appstore", "locale": "en-US", "name": "Habit Tracker: Daily Goals", "subtitle": "Streaks and reminders", "keywords": "habit, routine, goals, tracker, streak" }
  ],
  "appStoreApps": ["1438388363"],
  "countries": ["us", "de"]
}

Notes

• Counting is per Unicode character, as the consoles count. Byte size is returned as well for languages with multi-byte scripts.
• The App Store subtitle, keyword field and promotional text are not public: paste them in Listings to check them. Live reading covers the public fields only.
• Google Play listings are checked from what you paste; the Actor does not log in to any console.
• Issues and feature requests in the Issues tab are answered quickly.
