About

Appstro

Appstro is a free App Store analytics and ASO (App Store Optimization) tool at appstro.dev. It helps indie developers and marketing teams research keywords, track competitors, read reviews and compare app rankings across 175+ App Store storefronts, with no sign-up and no paywall.

What Appstro is

Appstro is an independent website, founded in 2026 and built and run by one developer. It is not affiliated with, endorsed by or sponsored by Apple Inc. App Store, iOS and iTunes are trademarks of Apple Inc.

Every tool on the site is listed on the tools hub. The most used are the App Store keyword tool, keyword rank checker, publisher rankings and the app directory.

Where the data comes from

Rankings, ratings, prices, descriptions and screenshots are read from Apple's public App Store and iTunes Search APIs, per storefront, at the moment you ask. Download and revenue figures are third-party estimates and are labelled as estimates wherever they appear. AI features run on a key you bring yourself. The site never claims a number it did not measure; where a figure cannot be known from public data, the page says so.

How the site is paid for is on the disclosure page.

What Appstro is not

Several unrelated companies use a similar name. Appstro (appstro.dev) is not appstro GmbH, a German software agency, and it is not the Appstro astrology app. If you were looking for either of those, this is the wrong site.
