Pink Print

Daily visual DNA distance. On-device. Private.

Open Pink Print once a day. Pick today's photo. Pink Print reads its visual fingerprint, a 768-number summary of how the photo looks, and shows how far it sits from your last print. Save the thumbnail and the fingerprint with an optional note. The year wall orders every print by visual similarity.

How it works

Open Pink Print. Today waits for one photo.
Pick today's photo from your library.
Pink Print reads the photo's visual fingerprint on your iPhone.
Pink Print shows the distance from your last print as one number.
Save the thumbnail and the fingerprint, with an optional one-line note.
Open the year wall to see every print, ordered by visual similarity.

What makes it different

Pink Print is the only Danielius Studio app built around Apple's Vision feature-print API. Other studio journals collect one color, one tap, one sentence, one annotated page, or one voice memo per day. Pink Print is the visual-distance template: a number that says how different today's photo is from your last one, scored from a 768-number visual fingerprint. The distance is the artifact, not your typing.

This is not face recognition, not a biometric fingerprint, and not facial identity. It is an image embedding for similarity comparison only.
