BortleBuddy is an all-in-one astrophotography and stargazing planner. It scores the moon, the weather and the light pollution at your exact location, then gives you one answer: EXCELLENT, OKAY or AVOID.
You know before you drive out, not after you unpack.
Built for everyone. First-time stargazers with a decent smartphone. Seasoned deep-sky imagers. Families who just want to see the Milky Way.

🌍 OUR MISSION
Light pollution is one of the most overlooked environmental problems of our time. It disrupts human sleep, disorients migrating birds, confuses sea life, and slowly erases our view of the night sky. BortleBuddy exists to change that, one photo at a time. Pick up your phone, find a dark sky, shoot a shining star, and see for yourself what we are losing.

🌑 LIGHT POLLUTION MAPS
See Bortle-class light pollution across your region in detail. Find the darkest skies near you, built on published sky brightness research and refreshed as new data lands.

🔭 SMART DARK SKY FINDER
Discover dark sky parks, remote sites and hidden spots worth the drive. BortleBuddy weighs Bortle class, horizon quality and distance, so you spend less time researching and more time under the stars.

🌤 ASTRONOMY WEATHER FORECASTING
Go beyond a normal weather app. Cloud cover, atmospheric transparency, seeing and wind, hour by hour. The app names the clear hours, so you know exactly when your sky will perform.

🌌 AUGMENTED REALITY SKY VIEW
Point your phone at the sky and explore constellations and the Milky Way in live AR. Tap a constellation label to reveal the artwork overlay. A sky guide that feels like magic.

📍 PERSONALIZED PLANNING
Save your favorite sites, track moon phases and plan around astronomical events. BortleBuddy brings the best skies to you, on your schedule.

🤖 BORTLEGPT, YOUR FIELD ASSISTANT
Ask what settings to use for the Milky Way tonight, why your stars are trailing, or what to shoot from a Bortle 5 backyard. BortleGPT answers astrophotography questions in the field, with your location and conditions already in mind.

📸 BUILT FOR ASTROPHOTOGRAPHERS AND FAMILIES
Whether you are capturing your first Milky Way shot or planning a multi-night deep-sky session, BortleBuddy works with any camera setup. No telescope required.

Stop guessing. Start shooting. Find your perfect dark sky tonight.
