I am an amateur stargazer and do this as my hobby. It’s hard to know when the conditions are good. I had a trip planed to a local dark sky zone. I checked this app and it said the conditions were poor. As this to me sounded rather strange for the place I was going to. I then checked an app I regularly use for stargazing and it said the conditions were excellent and I went ahead with the trip. When I arrived the sky was so clear! I could see many planets and constellations. I think this app could be something good if it had more up to date and more accurate reports. So I do hope that the developers take this advice into consideration and change the app for the better. ### 5/5 — Helps you find aliens. *2018-06-13* This app is great for anyone looking for aliens in the sky. Aliens are invading and this app can help you find them. It’ll show you the very best places to look for aliens. Aliens hate light so the app shows you where the light pollution is. Aliens also hate clouds so it has a handy feature that shows you if there will be clouds. Lustar is the ultimate app for avoiding abduction and yes it can help you find the perfect stargazing spot too. ### 5/5 — A big help *2018-06-11* When I moved to a bigger city I was upset about never seeing the stars anymore (I grew up in a rural area). This makes planning stargazing a lot easier. I’ve been telling everyone about it. ### 5/5 — A stargazer’s best friend *2018-06-05* So glad to have an app that puts all the necessary pieces into one place. Makes stargazing so much more enjoyable, especially during the rainy season. ### 5/5 — Great app! *2018-06-05* Tons of potential here. I use this app for planning my astrophotography sessions when camping and traveling. ## Frequently asked questions about lustar ### What is lustar? lustar is a free weather app that provides hourly stargazing forecasts by integrating local weather predictions with light pollution data.
