Appstro

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 and iOS 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.

Everything is read at the moment you ask, in the storefront you choose. Nothing on a tool page is a figure the site did not measure; where a number cannot be known from public data, the page says so.

• Listings, ratings and prices come from the App Store itself, one storefront at a time. Rating counts are kept separately in every country, which is why the worldwide tools check each storefront.
• Search positions on the App Store’s first page (10 to 12 apps) are read in the App Store’s own order and shown as #N. Apple publishes nothing deeper, so positions past the first page come from Apple’s public search API, whose order differs from the App Store’s; they are approximate and shown as ~#N.
• Top charts and history come from the App Store’s charts, recorded once a day. Release markers show what happened around a release, not what it caused.
• Download and revenue figures are third-party estimates from Sensor Tower: worldwide, for the last 30 days, and coarsely rounded. A value such as “< 5k” is a floor, not a measurement. They are labelled as estimates wherever they appear.
• Reviews are the ones the App Store shows on an app’s page: about ten per storefront, chosen by Apple, so they are a selection rather than a sample.
• Rules and limits (character caps, deadlines, guidelines) are quoted from Apple’s documentation and link to the page they came from.
• When the App Store does not answer, the page says it could not check and offers a retry. A failed check is never shown as zero or as “none”.
• AI features run on a key you bring yourself.

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

Appstro is free. There is no paid tier, no expiring trial and no card. Most tools work without an account; the ones that have to remember something for you — keyword tracking history, the watchlist, the feedback exchange — ask you to sign in, and nothing else does. The AI features are free here too, but they run on a Google Gemini API key you bring yourself, so anything Google bills for that key is yours rather than ours. How the site is paid for is on the disclosure page.

How much does Appstro cost?

Nothing. Appstro is free. There is no paid tier, no trial that expires, no card, and no usage cap to buy your way past.

Do I need an account to use Appstro?

Not for most of it. The majority of the tools run without signing in. An account exists only for the features that have to remember something for you, such as the keyword tracking history, the watchlist and the feedback exchange.

Is there a catch, or a paid upgrade later?

There is no paid upgrade to sell you. How the site is paid for is written out on the disclosure page rather than left implied.

Do the AI features cost anything?

Appstro charges nothing for them, but they run on a Google Gemini API key you supply yourself, so whatever Google bills for that key is yours. Nothing on the site is billed through Appstro.

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.
