Uncover the ways Henning Poulsen (the company) bills you and cancel your Sun & Moon 3D Planetarium Pro subscription.
A few things to note and do before cancelling:
1. • Notifications notify you of sunset, sunrise, new moon, full moon, solstice, equinox (the sun passes equator and day and night have nearly equal length), and these can be turned on or off.
2. This app calculates the sun and moon positions very accurately with an error margin of up to 0.03°, which is good in most cases, however, always refer to table values for most accurate calculations of solar eclipse and the like, since they require more powerful calculations.
3. • You can change between Sky View and Space View, where each cellestial body's position in space is carefully and correctly calculated, however distance and sizes of sun and moon have been resized to make them visible.
4. Point your iPhone to the sky and explore the movement of the sun, moon, planets and stars across the sky while you change time by swiping the display.
5. The sun and the moon have an angular diameter of approximately 0.5°, and with an error margin of 0.03° each, eclipse times are calculated with an error margin of ± 10 minutes.
6. It will work with no network coverage, and in flight mode, however showing your location as an address requires internet connection.
7. • Predict the positions of the sun, the moon, or the planets for any time for any position on Earth.
8. You can even change your location -- wondering how the sky looks where there's midnight sun? Or try setting your location to the other side of the equator and watch the sky rotating in the opposite direction.
9. • Sunrise, sunset for any given date - just swipe the sky view.
10. Showing the sattelite view on ground requires internet connection.
11. • A today widget gives fast access to the essential data about sun and moon, including a red arrow pointing in its direction.
12. With no internet, timezones are off, so if you simulate the sky from another location on Earth, the times are your local time.
13. • Share to friends and involve them in the fascinating world of Sun and Moon watching.
14. Waiting for full moon? Get notified when it occurs.
