Questions
Where does the data come from?
Apple's public App Store listing and review feed for the country you pick. Reviewer names are left out.
What does it cost?
Nothing; it is free. New accounts also get $5 to try the paid use cases.
How accurate is it?
Everything is counted, not judged by AI: stars, how many reviews use a word, quotes as written. It covers the written reviews Apple shows (up to 500 per app), not all ratings, and unhappy users write more often, so the share is higher than the overall rating suggests.
Will the other company know?
No. It reads public App Store pages.
How often should I run it?
Weekly. Ask your AI assistant to check your app and your top competitors every Monday; each check is stored, so the next one shows new versions and rating moves.
What if an app shows no reviews?
Apple's review feed sometimes answers empty for a few hours. The check then shows the reviews it already stored and says so; try again later for new ones.
