Star Chart Support & FAQ:
AR Support: Please note that Star Chart requires an iPhone 3Gs / 4 or iPad to function in Augmented Reality mode. This is due to the requirement of a compass included in the hardware. Star Chart will work on older iPhones and iPods, but you will be required to pan through the skies using your fingers.
AR issues: On devices with a built-in compass Augmented Reality mode should kick-in automatically upon startup. If it does not, please ensure the AR-mode toggle button at the bottom of the screen isn't disabled:
AR enabled: 
AR disabled: 
Time and Time Zone: Ensure your device is set to the correct time, and just as importantly, the correct time zone. Star Chart needs both these pieces of information in order to work properly.
Location: Star Chart also needs to know where you are located to accurately draw the skies as you would see them in your current location. Where possible we get this from GPS data available to us on your device. If Star Chart displays LAT: 0.00 LON 0.00 in the top left of the screen, then Star Chart has failed to get GPS data. There can be multiple reasons for this, ranging from your device's built-in technologies not supporting GPS, your personal device settings disabling GPS, the "Use GPS" toggle in Star Chart's "Set Location" menu option, as well as GPS signal strength in your current location.

Compass: Sometimes devices with compasses lose accuracy and the compass needs recalibrating. This is often the case when you experience either "stickyness" or lack of movement, obviously inaccurate directional pointing (you know you're pointing north, but Star Chart seems to be pointing another direction) or if the screen pans in a different direction to your physical movement. If this happens, hold your iPhone out at arms length and make a figure-of-eight motion with your arm three or four times. This should recalibrate it.
More serious issues: If your problems with Star Chart are more severe than those mentioned above, we ask that you reinstall the app. Delete Star Chart from your Home Screen and re-install it by downlaoding it again directly from the App Store (you will not be charged again). If your problem persists, please contact us on:
Finally Star Chart only works on Earth. So please don't take it with you on interstellar missions - it'll only get you lost ;).
