Free online database of all apps and their third party trackers.

I made an Android app that lists the trackers on your phone.

You can checkout that app by going to https://AppGoblin.info/about and clicking the link there. It is a test url for an open source ad tracking software. (ie track where an install came from, in this case the about page of the site).

Feel free to reach out if you're interested in either project.
