LookUpTonight vs SkyWindow

When was the last time you left the city? When was the last time the night sky actually stopped you in your tracks? Maybe tonight is that night. You want to stargaze. So you open the weather app. Check the moon. Google what’s visible. Wonder if clouds will ruin things at 2 AM. Open another tab. Still no clear answer. Too much research. Too many tools. Not enough sky. The answer LookUpTonight answers one question: Should I go outside tonight? Open the app. Get a stargazing score from 0–100 and a plain verdict — GO, GOOD, MAYBE, SKIP, or DON’T GO — plus a short line that tells you what it means for your night. No deep research. One tap. Decide. Go. What it does TONIGHT — your verdict • Stargazing score (0–100) built for observers, not commuters • Clear verdict with a human read on the night — not just a number • Live sky background — moon phase, clouds, and stars that reflect conditions at your location • Pull to refresh when you want the latest forecast WHY THIS SCORE • Short checklist — clouds, moon, planets, wind, humidity • Uses hour-by-hour weather through the observing window (astronomical night), not daytime “partly cloudy” • Best observing window when conditions are worth going out • Light pollution context (Bortle scale) so you know what’s realistic from where you are — and when a darker site is worth the drive VISIBLE TONIGHT • What’s above the horizon at your spot — planets and notable objects, with timing and direction CALENDAR — plan ahead • Multi-night forecast with a score for each night • Tap any night for the full breakdown • Compare evenings before you leave the city for dark sky YOUR LOCATION • GPS or search any city • Save favourite spots — home, dark-sky site, weekend getaway • Scores and sky conditions follow you wherever you observe Built for real stargazers LookUpTonight is for anyone who’s tired of juggling apps and still unsure at midnight.

SkyWindow tells you what you can actually see from your backyard tonight — not a generic all-sky chart. YOUR REAL SKY Capture your horizon with your phone (eight compass directions). SkyWindow uses AI to trace trees, roofs, and buildings, then filters every target list to what clears your skyline. TONIGHT'S VERDICT Get a clear GO, MAYBE, or STAY IN call based on cloud cover, wind, moon phase, and how many good targets are up for your site and gear. EQUIPMENT-AWARE TARGETS Add telescopes, binoculars, or a Seestar S30. Targets are matched to your field of view and aperture — no more hunting for objects you can't frame or resolve. PLAN & LOG Drag targets into an observing plan, browse the calendar, and log sessions with notes and what you saw. EVENING REMINDERS Turn on notifications in Profile. Around 8 pm local time, SkyWindow can nudge you when skies look worth opening the app. LANGUAGES English, Deutsch, Francais, Espanol, and Japanese. Change anytime in Profile. SkyWindow is built for amateur astronomers who observe from light-polluted backyards — where the horizon matters as much as the forecast.
