Planisphere vs Watercolour Reference

Planisphere is an astronomy application that lets you use pinch and finger gestures to manipulate a map of the sky. As you zoom in finer detail comes into view. You can double tap on objects to get more information. You can use the compass and accelerometer to show the sky in the direction the phone is being held for the selected time. Planisphere shows all 88 constellations and their boundaries, 6096 naked eye stars, the Messier deep sky catalogue, bright NGC objects, the Sun, Moon, planets and the now dwarf planet Pluto. These can be searched and then displayed if above the horizon for the selected time. Rise and setting times are available for all named objects. The date, time and location can be changed. With Location Services you can show the sky as it appears from your exact location or you can click on a world map or select a city. There is also a realtime mode that will update to the current time. You can also set a Night Light' which gives the map a red tint for nighttime viewing. Moon, Mercury, Mars, Venus, Jupiter and Saturn atlases are also available on the App Store.

Watercolour Reference has been designed to assist watercolour artists and painters, either beginners or the more advanced. This app assists the artist in the choice of appropriate colours and shades by providing data on individual colour characteristics and suggesting colour mixes/combinations and tips for a variety of topics. Suggested colour mixes can be viewed on your Apple Watch for quick reference. The Paint Mixing simulation allows you to choose up to three colours and mix them together in varying quantities to produce an estimate of how they might mix in the real world. Watercolour Reference currently uses the watercolour portfolios of Winsor & Newton and Daniel Smith. Included with this app are suggested combinations for portrait and flower painting plus a general watercolour characteristics database. Additional categories can be purchased in-app.
