Easily and quickly identify and locate stars, planets, constellations and more with a touch or by simply pointing to the sky. Have fun with family and friends discovering the images in the night sky. Go outside and explore the night sky. Displays the sky view at the correct orientation when held at any angle not just landscape or portrait. Simple operation, no buttons to press or modes to select, just point to the sky to start exploring. Unique rotation scheme enables touchless navigation even for the iPod touch without a compass.
This review was originally posted on VersionTracker.com. In addition to this app I have tried iAstronomica and Starmap. Overall I prefer this to the other two.
It is fast, has a lovely interface. Makes use of location services.
Would like an ephemeris though.
