List your app on Duoworthy

Duoworthy checks every listed app against Apple's iPhone Duo signals each day, and tests some by hand on a real iPhone Duo, posture by posture.

Add your app

We keep only a hash of it, to stop repeat submissions. We don't write to you.

We list it once Apple's Lookup API confirms it's an iPhone app, then check its App Store listing for iPhone Duo screenshots right away. What the page shows is the automatic status until a hand test exists.

The badge

Link to your app's page with a small badge. It shows the hand-test verdict when there is one, and the date of the last automatic check otherwise. It never says “Made for iPhone Duo”: that's Apple's.

Replace chatgpt with the slug in your app's Duoworthy address.

Fast-track hand test

Coming soon. A hand test of your app on a real iPhone Duo, sooner than the queue would get to it. Prices aren't set yet.

Sponsored placement

None exists today. If it ever does, it's labeled “Sponsored”, everywhere it appears.
