Free app-ads.txt checker

Paste an App Store or Google Play link. We fetch the app's app-ads.txt and check every line against the ad systems' sellers.json, with the same checks as the index.

Check app Usually a few seconds; very large files can take up to 30.

Results are automated observations of public files. They describe file contents, not the intent or conduct of any company. We record which apps are checked, not who checked them. Limit: 20 checks per hour.
