Uncover the ways Henning Poulsen (the company) bills you and cancel your Sun & Moon 3D Planetarium Pro subscription.
Note 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 may be calculated with an error margin of ± 10 minutes.
