About
Should you go outside and look up tonight?
Star Tonight answers with one number. Enter your town and tonight's cloud cover, moon, darkness, light pollution and transparency roll into a score from 0 to 100, a straight answer (YES, MAYBE, NO), and the best hour to be outside.
What you get:
• Tonight's verdict, hour by hour through the night (scored until 3am, or all the way to dawn if you're a night owl)
• The best window to go out, so you're not standing in the cold at the wrong time
• A 7-night outlook to plan the good nights
• Moon phase, rise and set, and how much of the night it's up
• Meteor shower calendar with peak-night reminders (Perseids, Geminids, Orionids and more)
• Aurora watch from NOAA space-weather forecasts
• Which planets are up, where to look, and when
• A light-pollution setting so a city sky and a dark-sky park get honest scores
• Red-light mode to protect your night vision
• A share card for the group chat: "YES for stars in Hartford tonight, 84/100"
No accounts. No ads. No tracking. Astronomy is calculated on your phone; weather comes from Apple Weather and space weather from NOAA.
Built in Connecticut by a guy who got tired of driving out to the lake on a cloudy night.
