Orbit Beacon is a small private world clock styled like a satellite control deck. Your home city sits at the centre of a deep-space mission console as the GROUND STATION; every contact you add becomes an amber BEACON placed on an orbital shell at its hour-offset angle around the station. Read the console at a glance and you know exactly where everyone is on the planet without doing hour math. The action lives INSIDE the console -- you tap the cyan station core to launch a new beacon. No FAB, no banner, no top pill.
THE CONSOLE
A 220px circular mission console with three orbital shells (1h, 6h, 12h distance from station), a meridian crosshair, and cardinal hour markers (00 at top, 12 at bottom, -6 left, +6 right). Each contact is a small amber beacon placed at angular position `(offsetHours / 12) * 180 - 90` degrees, with its airport-style 3-letter code underneath. Pinned contacts get a coral flare ring around the beacon.
THE STATION CORE
A bright cyan core sits at the very centre of the console. Tap it and a compose sheet pops up: name, city picker, notes. The core is your STATION -- the action is the most reachable position on the screen by design, and the visual element doubles as the affordance.
THE TELEMETRY LIST
Below the console is a compact single-line TELEMETRY of all your beacons. Each row: small amber beacon dot, airport code, city + name + hour delta, big local time. Reads like a mission readout, dense but legible.
THE OVERLAP WINDOW
Just below the console, a single line reports the longest contiguous overlap window in your local clock, when everyone is inside working hours at once -- in plain numbers like "WINDOW 14:00 - 17:00". Below it, the hint "TAP STATION TO ADD BEACON" reminds you where the action lives.
THE ORBIT VIEW TAB
The second bottom tab is an "Orbit" view -- every unique city you track, sorted by hour offset. Each row: city name (or your custom label), IANA id, day-shift hint, contacts in that city, delta badge, big local time. A + ADD CITY pill top-right opens the same searchable picker. Long-press a row to remove all contacts in that city.
THE EDITOR
Tap a beacon to open the editor. Name field, city picker (115+ IANA cities plus raw UTC offsets), free notes field. Save, pin, archive, or delete from a row of action buttons at the top.
SETTINGS
Pick your STATION city. Add a custom display label. Toggle 24h vs 12h clock. Tune the working window to any whole hour 0-23 using +/- steppers or by typing.
PRIVACY
Orbit Beacon keeps every beacon on your device. No sign-in, no cloud sync, no analytics, no ad SDK. The store is encrypted at rest with a key that lives in the Android Keystore. No network permissions are requested. If you uninstall the app, the data goes with it.
