Live Sky — Real Astronomy on Your Wrist
· v5.1.9
About
Your wrist becomes a planetarium.
Real positions of sun, moon, planets, and constellations — for YOUR location, in real time.
Live Sky turns your wrist into a real-time planetarium. See the sky exactly as it is above you right now: the Sun, the Moon with its real phase, the planets, the stars and the Milky Way, all computed for your location and time.
The sky, live
Sun and Moon in their real positions, with accurate Moon phases.
All 7 planets (Mercury, Venus, Mars, Jupiter, Saturn with its rings, Uranus and Neptune) at their astronomically correct relative sizes.
Stars, constellations and the Milky Way during deep night.
The background follows the Sun: full day, sunset and sunrise (civil and nautical twilight) and deep night.
Real weather
Current temperature with a sky-condition icon (with Moon variants at night).
Weather backgrounds: cloudy (in day, sunset and dusk tones), rain and snow.
Tomorrow's forecast: low and high, a weather icon, and a little character that tells you how to dress (light or warm, with an umbrella when rain is likely).
The little touches
Deep-space objects: ISS, Hubble, James Webb, Voyager 1 & 2, Pioneer and the Parker probe appear at night and rotate every hour.
4 watch styles: Digital, Solid Lunar, Analog and Solid Digital.
2 complication styles (Hexagonal and Radial): battery, steps, heart rate, date, calories, Body Battery and distance.
Color palettes, cardinal points and subtle dark plates so everything stays readable over any background.
Optimized for round AMOLED displays. Available in English and Spanish.
Help me make it better
I build and improve this watch face independently. Which feature do you like most? Drop it in the reviews: it helps me decide what to polish next. Also let me know which watch you use and whether it looks good on your model.

Thanks for trying it.
What's new
v5.1.9
Important stability fix
- Fixed a memory error that caused the watch face to restart or
show "IQ!" from time to time (Out Of Memory).
- Optimized the sky calculation and background loading: lower
memory usage and more stable performance across all watches.
v5.1.7
Now runs on Fēnix 7 and many more!
- NEW: support for 16 transflective MIP watches:
Fēnix 7 / 7S / 7X (incl. Pro/Solar), Forerunner 955 / 255 / 255S,
Enduro 3 and Fēnix 8 Solar. Same live sky with time-of-day
backgrounds, planets, Moon, ISS and weather.
- The ISS and its alert are now a bit larger.
- Memory optimizations for smooth performance across devices.
v5.1.6
- New "Emoji" complication style: flat color icons (battery, steps, heart rate, calories, Body Battery and distance), without the hexagonal frame. Selectable from settings, alongside the Hexagonal and Radial styles.
- Improved ISS alerts: passes now load faster and more reliably after installing.
v5.1.4
- International Space Station (ISS) alerts: shows when it passes visibly over your location (day and time), with an astronaut holding the time and the ISS crossing the sky in its real position.
- New Pillar mode with optional astronomical info: Sun and Moon rise/set times and the next two ISS passes.
- Cleaner Moon artwork.
- Evening forecast.
Newly supported watches:
MARQ 2 / MARQ 2 Aviator, Approach S70 (42 & 47 mm), Descent Mk3 / Mk3i (43 & 51 mm), fēnix 8 43 mm, fēnix E, Instinct 3 AMOLED (45 & 50 mm), and Venu 4 (41 & 45 mm).
What's new in 5.1.2:
- New "+50%" celestial body size option (Sun, Moon, planets) — now Normal / +20% / +50%.
- Fixed an issue where the temperature next to the weather icon would occasionally disappear.
What's New in v5.1.1
NEW FEATURES
- Full English & Spanish localization (auto-detects your watch's language)
- "Pilar" watch mode — stacked HH/MM with large date & weather block
- Toggle to enlarge sun, moon and planets by +20%
- Cardinal points toggle (N/E/S/W)
- Monospaced time digits option
- Persistent last known location (no more resets)
ASTRONOMY IMPROVEMENTS
- Bright star names (3-letter labels, gated by hemisphere)
- Constellation names (Orion, Crux, Ursa Major, Cassiopeia, Centaurus)
- 16 new stars and 3 new constellations
- 4 unique deep-space objects at night (no more duplicates)
- Celestial bodies sink astronomically correctly below horizon
- Sun/moon/planet arc adjusted for northern hemisphere
VISUAL POLISH
- Anti-overlap label system
- Improved rain alert iconography
- Cleaner spacing for "0" in mono time
- Horizon line removed from Digital mode
UNDER THE HOOD
