There's no category for the sky. So we filed Cerebral under the mind. Cerebral is a daily cognitive lens. Each morning it reads the real sky — computed on your device, from first principles — and maps it to four elemental modes of thinking: the spark, the structure, the signal, the depth. Not a forecast. A mirror. Mapped, not predicted. ◈ TODAY'S FIELD — the day's leading element, read against your own. ◈ YOUR PORTRAIT — your cognitive field, from your birth moment. ◈ THE WHEEL — your whole sky, placed: planets at their real longitudes, the aspect web, every degree computed live. ◈ THE MATH — the glass box. See exactly how it's calculated. No black box, ever. ◈ REFLECT — a quiet journal that reads each day against your field. ◈ TWO FIELDS — bring another person's field in (AirDrop, or link two phones directly) and read where two minds meet, where they stretch, and the field you make together. Honest synastry: overlap, never fate. ◈ THE FIELD (Apple Vision Pro) — stand inside your elements as volumes of light. The doctrine: • On-device. No cloud, no servers. Your field never leaves your phone. • No account. No login. Ever. You're a guest, not a user — and a guest can leave. • Free. No ads. No tracking. No in-app purchases. Mapped, not predicted. Take what's yours. KenshoTek LLC · 925
