Pink Rune

A year wall of detected rectangles. On-device. Private.

Once a day you point Pink Rune at a photo with a rectangle in it - a door, a window, a sign, a screen, a painting. Pink Rune finds up to 10 rectangles in the image on your iPhone, outlines them, and shows how confident it is about each one. Save it with a one-line note, and the Year wall shows every rune you saved, the shapes you spotted around you.

How it works

Open Pink Rune and pick a photo.
Pink Rune finds up to 10 rectangles in it, on your iPhone.
The rectangles are drawn as a colored overlay, with how confident Pink Rune is about each one.
Add a one-line note and save. Pink Rune keeps a small copy of the photo with the outlines drawn on it, the corner points and the count.
Pin the Lock Screen widget to glance at today's rectangle count.
Open the Year wall to scroll every rune you saved.

What makes it different

Pink Rune is about the shapes, not the picture. What you keep is a small copy of the photo with the rectangles it found outlined on top, how many there were, and your note. Other Danielius Studio apps keep the photo (Pink Album), restyle the photo (Pink Hatch), or write a caption from the day. Pink Rune outlines the rectangles you noticed, and the Year wall shows every rune you saved.

What stays on your device

No accounts, no email, no signup.
No analytics, no third-party SDKs.
Apple Vision's rectangle detector runs on-device. The photo is never uploaded.
Only a small copy of the photo with the outlines, the corner points, the count, your note and the date are saved.
The only network call is to Apple's StoreKit when you choose to subscribe.
