Description

Sky turns your wrist into a window onto the sky above you.

Point your watch in any direction and Sky shows what is actually there: the Sun, the Moon, and any of the seven other planets currently above the horizon in that direction, tracked live as you turn using the watch's compass. Each body is drawn as a small icon, positioned by its real azimuth and altitude -- turn your wrist and the sky scrolls past like an AR window. 
The first dial now shows also Andromeda, Orion Nebula, Pleiades, Beehive Cluster, Hercules Cluster, the Double Cluster, and both Magellanic Clouds — drawn as small violet squares (vs. the planets' cerulean circles) and only appearing once the Sun drops below -12° altitude. Time and date are shown below the horizon.

Shake the watch for a second dial: a heliocentric diagram of the whole solar system, Sun at the center, all eight planets laid out on their orbits.

Under the hood, Sky computes every position itself with a low-precision orbital-mechanics engine written from scratch (the Astronomical Almanac's low-precision solar formula, a truncated lunar theory, and classic osculating Keplerian elements for the planets), running on the phone from your GPS location and cross-checked against PyEphem to within a fraction of a degree. The watch itself never does any of that math -- it only receives plain numbers over Bluetooth and places them on screen with simple integer arithmetic, keeping it fast and battery-friendly.

A small lightning-bolt icon appears beside the time if the phone connection is lost. A GPS-unavailable icon shows whenever the phone's last location fix failed, and hides once it succeeds.

This is an initial, experimental release. It's done with the skill (see https://repebble.com/blog/spring-2026-pebble-app-contest) using Claude.
