Pink Halo

Look once. Read your face.

Pink Halo captures a daily expression vector. Open the app, look at the TrueDepth front camera, and one frame is read by ARKit into 52 blendshape coefficients. The frame is discarded the moment it is read. Only the 52 floats and a single label (the dominant expression) are saved. Each day's halo joins your year wall, a grid of every capture and its expression. Pink Halo never uploads a photo and never connects to Apple Health.

How it works

Open Pink Halo. Tap the + to start a new capture.
Hold your iPhone in front of your face. The TrueDepth camera reads one frame.
ARKit extracts 52 blendshape coefficients (mouthSmile, browInnerUp, eyeWide, jawOpen, etc.).
The frame is discarded. The 52 floats plus a dominant-expression label are saved with today's date.
Open the year wall to see every halo you have saved, each with its dominant expression.

What stays on your device

The frame is never saved. It is held only long enough to read blendshapes, then discarded.
No photo, no video, no microphone, no Apple Health.
No accounts, no email, no signup, no analytics, no third-party SDKs.
Entries are stored on-device with SwiftData. Nothing leaves your phone.
The only network calls Pink Halo makes are to Apple's StoreKit when you choose to subscribe or buy Lifetime.

What you need

An iPhone with the TrueDepth front camera (iPhone X or later).
iOS 26 or later.
No microphone, no photo library, no location, no Apple Health.

Pricing

Everything is unlocked for your first 3 days. After that you can keep up to 3 captures for free. Pro unlocks unlimited captures:

Pro Monthly: $4/month.
Pro Annual: $25/year.
Pro Lifetime: $59 one-time.

All purchases are handled by Apple and managed under your Apple ID. Pro is Family-Shareable through Apple's standard Family Sharing.

Pink Halo is a journal, not a medical or diagnostic tool. The dominant-expression label is derived from the blendshape values and is descriptive only.
