About Sky Map

Sky Map transforms your Android device into a powerful handheld planetarium, allowing you to effortlessly identify stars, planets, nebulae, and more. Born from the legacy of Google Sky Map, this application has been generously donated and open-sourced, ensuring its continued availability and improvement. Encountering issues with map movement or inaccurate pointing? Ensure you're not in manual mode and that your device possesses a compass. If problems persist, try calibrating your compass using a figure-of-eight motion or consulting online resources. Be mindful of nearby magnets or metal objects that could interfere with the compass's accuracy. For users experiencing jittery map displays, especially on devices lacking a gyroscope, adjusting the sensor speed and damping settings can significantly enhance the viewing experience. No internet connection is required for basic functionality, making it ideal for stargazing in remote locations. However, manual location input relies on network connectivity. Join the beta testing program to access the latest features and contribute to the app's ongoing development. Explore the cosmos with Sky Map, your personal guide to the universe. Discover constellations and celestial objects with ease, making astronomy accessible to everyone. Perfect for both amateur stargazers and seasoned astronomy enthusiasts, Sky Map offers a user-friendly interface and accurate celestial mapping. Enjoy the wonders of the night sky with this comprehensive and portable star chart. Whether you're identifying constellations or tracking planets, Sky Map provides an immersive and educational experience.

considering the situation this app is in (development/developer wise) I really can't complain. It shows me more than I am looking for almost every time I open it. its a bit buggy at times when "pointing and shooting" but a simple switch to manual mode usually fixes it for the moment.. but from what I gather this app exists because of a few folks keeping it alive when they have extra time/ want to do it on their own time. and if thats true, im grateful for whomever is keeping this alive. kudos ๐Ÿ‘

Someone recommended Sky Map to me and I have been using it for several years now. I Love how easy it is to navigate! I have also found that calibrating seems to be easier and faster when you use a figure 8 motion rather than the 3 individual directions that it tells you to use when the calibration needs to be updated. I also find it useful to identify where the planets are lined up during astronomical events. I find Sky Map to be a very useful tool, day or night! Thank you for keeping it going!

I love it! If set to high calibration for motion in your accelerometer, it is very accurate. My friend holds a masters in astronomy, and they were surprised we could point the telescope easily with this application.

WOW! I don't know how I can possibly heap enough praise on this app! Everything about it is so good as to restore my faith in humanity. This app could be an example to developers everywhere. It has commonly-wanted settings right up front, and advanced settings are in some menus with appropriately verbose explanations. It does nothing bothersome, has no ads, and works flawlessly. How do I send this developer money? (For real.)

This app loads quickly and easily identifies the stars and planets. Point your phone to the sky and the star map is similar to direction the phone is pointed. Map can be zoomed in and back for specific stars.
