An honest check of your store listing.
Paste a link to your app. You'll see your screenshots the way the store shows them, and each check against Apple's or Google's own guidelines, with why it matters and what to change. If something can't be read from the public page, it says so instead of guessing.
What it checks
Every rule comes from Apple's or Google's published guidance, checked 21 Oct 2026, and each result links to its source. No invented benchmarks: the number at the top is simply how many checks pass. Anything we can only guess at is labelled as a guess and left out of that number.
