Excellent app, informative and easy to use. I only wish that the Android version had all the features described in the video. BTW, for the users complaining with variations of "location is way off": recalibrating your phone's compass should fix that.

The IOS version is phenomenal & used it for many years in the military aviation world for quick reference flight planning around astronomical/nautical/civil twilight to determine timelines around NVG flights; saved me from having to dig it up on clunky military software or call ATC. Now I have an Android phone & I couldn't be more disappointed. Why in the world wouldn't you use the same interface for android?! It degrades the planet viewing abilities too since you have to guess visibility time.

What's new

Titlebar hidden on devices with a dedicated menu button. Fixed problem that inappropriately disabled automatic orientation on some devices. Automatic orientation requires compass, gyroscope, and accelerometer sensors.
