juppy The ones that do have the green checkmark have a message on the bottom that says "UNKNOWN" When I click on that, it states " Since you haven't provided any verification info I am unable to determine the verification status" How do I provide verification info?
If an app is green/shows Success, then you can ignore the Unknown. That's just for manual verification and not needed if it already matches the database.
juppy Is AppVerifier developed by the Acrescent team or is it someone else?
They're separate projects with the same goal (safe apps for your phone) and complementary functions. Both being open source projects there's naturally some intermingling.
Accrescent lead: https://github.com/lberrymage
Appverifier lead: https://github.com/soupslurpr
Soupslurpr is also a member of the Grapheneos team (https://github.com/orgs/GrapheneOS/people), and with Accrescent being recommended by Grapheneos it all kind of just fits together like a jigsaw puzzle.
juppy I am assuming this is because they are not in their database is this correct? If so, why are there not more apps listed?
Correct and 1) Appverifier is still very much being developed and 2) it's a bit of work to add them:
Adding apps to the internal database requires checking where the app is being distributed, downloading them from those different sources, obtaining all the signing certificate hashes, and then adding it to the code and committing it.
Secure app stores are the true solution.
Such as Accrescent.
juppy How do I provide verification info?
It's very simple really. You just need to have the app's hash copied in your clipboard and press the Verify from clipboard button.
Unfortunately, not every developer posts the app hash where it's easy to find, which makes the whole thing rather more difficult.
Fortunately, you're not the only one with the problem so I recommend checking out these two threads here on the forum for more info (and there are more threads you can search for!):

Also here's a nice video by Side of Burritos explaining how to use Appverifier: https://youtu.be/IkrujqcM-9Y
