Ratings and Reviews
Always accurate, just wish I lived away from the city to use it more often. The only thing that could improve it would be an automatic alarm.
Great app. I love it BUT it lists satellites with an elevation of less than 30 degrees making them almost impossible to see. Arguably not the Apps' fault.
Lets me understand the sky and stars in an easy but fascinating way. Highly recommended.
