Know tonight before you pack the gear
One place for cloud trends, astronomical darkness, moon phase, and practical sky hints — tuned for your saved observing spots. No account; your locations stay on your device.
What You Get
Weather, moon phase, and darkness in one workflow — a steadier read on whether a night is worth setting up for. Forecasts aren’t promises; AstroGlade helps you compare nights instead of guessing from scattered tabs.
-
Stargazing Score
A 0–100 score with plain-language bands — a fast read on whether the night is worth setting up for.
-
Tonight’s Conditions
Cloud cover through astronomical darkness, how long your dark-sky window lasts, and hours that stay under a useful cloud limit — with air temperature, wind, and visibility spelled out for the night.
-
Forecast Length
Choose a week of hourly detail or a longer outlook so you can line up the better evening before you commit time and travel.
-
Moon & Darkness
Astronomical night length, moon phase context, and a straight read on whether the moon helps or hurts what you had planned.
-
Planets & Sky Calendar
Bright planets, sun and moon rise and set, meteor shower dates, and a rough Milky Way hint — all spelled as planning aids (not a replacement for a planetarium app).
-
ISS Passes
Next passes for your saved place when a live satellite track is available for your coordinates — use it as a schedule hint, not a substitute for official mission data.
-
Saved Places
Name and switch between observing sites; search for a town or use your device’s location once to set a spot up. No cloud of contacts — your place list stays on this device until you clear it.
-
Share Tonight’s Plan
Copy a short text summary for notes or messages, or share a link to AstroGlade itself — handy after you’ve picked a location.
-

Light, dark, or astronomy-tinted themes; adjustable text size; add to home screen like an app. No account — see the in-app Privacy section for how forecasts and locations are fetched.
