Made me a Stargazer

This app is great, especially for camping trips or beach weekends when the stars look really nice. I’ve been trying to teach myself to identify constellations for the last few years, and this app has helped a ton. Looking at the stars is so much more fun when you know what they are! The only problem I’ve ever run into is the automatic location service/orientation messes up in areas I have bad signal, but it’s easy to fix with the manual world map. I’ve had many memorable nights laying on the ground with friends enjoying the beauty of the cosmos because of this app!

The kid loves it!

When our young one saw it on, we were headed home. She asked what is that, we told her . This is star tracker, can I look at it. The rest of the ride home was question of what’s this, and what can I find for you. I tried to explain the stars in Orion’s Belt, that they were twenty times the size of our sun. She needed time to think of about that, needless to say she loved it. Thank you for the help, I hope our little one stick with it!. Thanks again!, J T .

Easy to use & works well

I had a prior night sky app. But it required WiFi and was a pain to use. Calibration was “iffy” and identifications were guesstimates. This app is fast and easy to calibrate, does not depend on WiFi, and show the sky with good accuracy. The planets are displayed far oversized, and shows the planet as observed in a telescope. But this helps you distinguish them from the stars, and they are shown in proper position in the night sky. I’m very happy with this app.
