Pink Print

Daily visual DNA distance. On-device. Private.

Open Pink Print once a day. Pick today's photo. Apple Vision extracts a 4096-dimensional visual feature vector, and Pink Print computes the distance from yesterday's photo. Save the thumbnail, the vector, and the distance number. Year end, you scroll a year of distance numbers as one visual mood graph.

How it works

  1. Open Pink Print. Today waits for one photo.
  2. Pick today's photo from your library.
  3. Apple Vision extracts a 4096-dimensional visual feature vector on-device.
  4. Pink Print computes the distance from yesterday's photo.
  5. Save thumbnail, vector, and distance number. One print per day.
  6. Pin the Lock Screen widget to glance at today's distance number.
  7. Year end, open the year chart for a full year of visual distances.

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 yesterday's, scored by Apple's 4096-dimensional feature embedding. 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.

What stays on your device

Requires iOS 26

Pink Print uses Apple's Vision feature-print API and requires iOS 26 or later on a supported iPhone or iPad. Older iOS versions show a clear message and do not save prints.
