The sizer

Three ways to size a finger.

Camera + card

  1. Lay any bank card flat on a table.
  2. Rest your finger flat on the card, base of the finger over it.
  3. Hold your phone directly above and capture.
Ready when you are. Tap Start camera below — nothing happens until you do. The picture stays on your device.
Asking for your camera… Your browser will ask once. The picture stays on your device.
No camera this time — that's completely fine. Take the photo with your usual camera app, then choose it below. It's read on your device and never uploaded.

Private by design — sizing runs entirely on your device. No photo is uploaded, ever.
What you just used

A working piece of the platform.

Everything above ran in your browser — the sizing math, the camera, the calibration. No photo left your device, and nothing was uploaded. In a live deployment this same component sits inside the guest portal under your center's name, and the size it produces flows straight into ring fulfilment with the reservation.

Runs on the guest's device

The photo and the math never leave the phone — a privacy posture guests can verify for themselves.

Branded to your center

In production the sizer lives inside your portal, under your name, styled to your brand.

Wired to fulfilment, not an inbox

The size flows straight to ring fulfilment with the reservation — no email thread, no guessing.

Why it matters

What starts after the sizing.

Sizing is the first thirty seconds of the Baseline program. What follows is two weeks of nights before arrival, then months of recovery arc after departure — one continuous picture in the guest's own portal. Here's the shape of it:
