Raytraced from your real geometry
The dial orients to the world around you. Sun bearing and altitude on the ring, your shadow drawn opposite it at true length, sunrise and sunset marked at the exact bearings they cross the horizon — corrected for the ridge in front of you, not the flat-math one.
Drag the hour and the shadow answers — 6:45 PM, 15 ft. 7:38 PM, 27 ft. 8:10 PM, 48 ft and right across the yard. Drop in a tree, a pergola, a vehicle or a solar panel and its shadow moves the same way. Tap any spot to read its hours of direct sun.
On iPhone Pro, LiDAR captures the real geometry and every surface gets raytraced direct-sun hours — the fence line, under the tree, the strip beside the shed. Month by month, all year.
Plants scored against your hardiness zone, your soil and your measured light — with a straight answer about timing. "Last call — past the ideal window, but sown today it can still make it. Harvest ~late Sep, 24 days before frost."
Scan once, then reopen that scan on any date — winter light, June solstice — without rescanning. Place beds and structures and watch their shadow cost update live.
Windows built from sun and moon position, season and light at your exact coordinates — then checked against the water itself. Live stream temperature from the nearest gauge, and the hatch that temperature actually implies.
"100° today, sunset at 8:49 PM. Best window to be out: 4–9 PM. Keep it shady — strong UV, hat, shade, sunscreen." One card that tells you what to do with your afternoon.
Sun and moon events, prime activity windows, frost tonight, air worth checking, aurora possible, severe weather for the ground you're standing on. Every category switchable, quiet hours respected, and all of it scheduled on the device — there is no push server.
Not a shrunken phone screen. The watch carries the dial, the day, the air, the burn timer — and the flies that are hatching right now, ranked, with sizes.
Sun, moon, shadow, planting windows, activity windows and every field guide compute on the device itself. Drop into a canyon with no signal and the important half still works.
