Watercolour Reference vs BWP

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.

Birds of the Western Palearctic – BWP – is the definitive reference for everyone with a serious interest in birding and ornithology. Fifteen years ago we published all 11 printed volumes on DVD-ROM. Now we have fully overhauled this renowned BWPi for iOS and macOS. We have refreshed the design, breathed new life into the plates, added a comprehensive video library, integrated unique breeding birds content and updated taxonomy with new species and splits. Comprehensive coverage of every species that regularly occurs in the region, with sections on Field Characters, Habitat, Breeding, Distribution, Population, Movements, Social Pattern and Behaviour, Voice, Food, Plumages, Moults, Measurements and Geographical Variation. The app covers every species known to have occurred within the region, and we will be updating the app as new species occur (latest is Horned Puffin!). BWP integrates with Collins Bird Guide app so that you can switch between the two seamlessly. • 1,056 species covered • 5,473 illustrations • 1,066 songs and calls • 916 videos • 643 distribution maps • 10,176 photos of breeding stages • 1,557 line drawings showing behaviour • 288 life cycle diagrams • 2,446 tables • 37,690 references • 5,250,000 words of text! • Species names are translated into 25 languages The distribution and population data have not been updated since BWP was originally published, and some species have changed significantly since then. Compare species is available on iPad only.
