★★★StarTracker HD is out! Incredible fluid StarGazing experience at 60fps!★★★
It's so excited to introduce you the best 3D Sun and Moon Virtualization app on iPad!
This is a virtual 3D compass sphere which shows the position of Sun and Moon in the sky with perfect application of virtual reality technology! Full utilization of the build-in digital compass and accelerometer drive the best user experience.
With the cutting edge signal processing technique and applying the raw data directly from the build-in digital compass chip instead of the existing degree provided by Core Location API, this app has fast reaction and high accruacy, which is as fast as the gyro app Jobs shows on the WWDC ;)

- The 3D compass in a fantastic crystal ball will always point to the True North, no matter you rotate or position the phone in which direction.
- You could see the current position of the Sun and Moon simultaneously on the 3D compass ball, and the 24-hour orbit of the Sun and Moon will be displayed as a circle surround the ball.
- Display the time of Sun rise/set and moon rise/set.
- Time and date can be adjusted smoothly, the position of Sun and Moon will move simultaneously with the changing of the date or time.
- User can choose current location from a world map by trigger the top left location button, this is mainly designed for iPad WIFI version which may not get the location from core location framework.
- Smooth motion flow and quick response which is realized by cutting edge signal processing technique.
- Superb high quality graphic display by full screen anti-aliasing and HDR technology employment.

A wonderful experience you never had before!
Just Go and Enjoy it!

Beautifully fluid display

Excellent depiction of orbits. I wish though, that it had a manual mode to select our viewing angle. We should be able to study it in various angles w/o having to move our chair around to do it. Future versions could be really spectacular, if we could zoom out and see the solar system. If that ability is ever added, I hope it is not in a separate program. I'd certainly upgrade (this version) to an enhanced version with planets. The author knows how to make great instructional displays, and I hope this is only the beginning of more great stuff to come.

Great app, fluid compass

WOW, a 3D compass on iPad, with the sun and the moon's position and orbit showed in an intuitive way, just like a Planetarium in your hand, very impressive! The compass is very fluid to view at any angle, it's just like there is a gyroscope inside, very fast reaction and incredible accurate.
The graphics is amazing and it's interesting to adjust the time and date, to see the sun and the moon moving around their orbit with moon phase changing.
Fantastic, must have for anyone looking for the highest quality 3D compass that's shows the sun and the moon's orbits!

Nice, Augmented Reality

A refined and useful 3D compass with sun/moon path and set/rise time calculator, highly recommended for planning watching sun rising and for photographer usage.

With 3D Augmented Reality feature, it's intuitive to get the real path/point of the sun/moon, the graphics is gorgeous, and the sleek and responsive control make this more fun, especially for educate kids during the playing.
