Frequently Asked Questions

Is RespectASO really free?

Yes. RespectASO is 100% free and open-source under the AGPL-3.0 license. There are no paid tiers, no usage limits, and no data collection. You run it on your own machine via Docker.

Do I need any API keys or credentials?

No. RespectASO uses only the public iTunes Search API, which requires no API keys, credentials, or accounts. Just clone the repo, run Docker, and start searching.

Does any data leave my machine?

No. RespectASO runs entirely on your local machine inside a Docker container. API calls go directly from your machine to Apple's servers. No data is sent to Respectlytics or any third party. The source code is open — you can verify this yourself.

How is keyword popularity estimated?

Each keyword gets a popularity score from 1 to 100 based on public data from the iTunes Search API. Higher scores mean more search volume. The algorithm is fully open source — you can inspect and modify it on GitHub.

How is keyword difficulty calculated?

Each keyword gets a difficulty score from 1 to 100 based on the strength of competing apps. Scores range from Very Easy (under 16) to Extreme (91+), so you can quickly see which keywords are within reach. The algorithm is fully open source.

How are download estimates calculated?

RespectASO estimates how many daily downloads you could get at each ranking position (1–20) for a given keyword. You get both conservative and optimistic ranges. The algorithm is fully open source.

What countries does RespectASO support?

RespectASO supports 30 App Store regions including the US, UK, Canada, Germany, France, Japan, Australia, Brazil, India, South Korea, and more. The Country Opportunity Finder lets you compare keyword performance across all 30 countries at once to find the best markets.

Does RespectASO support Google Play / Android?

Currently, RespectASO focuses on iOS App Store keywords using the iTunes Search API. Google Play Store support is on the roadmap — the Play Store has no official public API for keyword data, which makes it more challenging to implement.
