Innovative user experience concept

Through the native implementation for iPhone and iPad as well as for Android and the development of special control elements a maximum user experience and usability was achieved.

The directly integrated, interactive finder allows a quick identification of the animals based on specific characteristics. For example by size, colour or distribution areas on a modern, interactive map.

Ralf Kiefner is a well-known whale and dolphin expert, whose book "Whales and Dolphins, Worldwide" has been translated into 5 languages and is generally considered a "must have" by whale watchers. The photos and video clips used in the app have been collected over the course of more than 20 years. The comprehensive library is constantly being expanded.

Development first for iOS

The entire usability concept was first developed and implemented completely for iOS. Afterwards the concept was ported to Android. By concentrating on one operating system at the beginning, costs were saved, especially in bugfixing and the continuous improvement of the UX concept.

Over 68 species of whales and dolphins

The app describes 68 species of whales and dolphins in an entertaining way and contains as much information as a good book, but offers much more. For each species there is a Quick-ID, complete description, information about behaviour, diving behaviour, food, reproduction, possible hot spots, interesting facts, popular names, key figures, information about taxonomy, scientific name and distribution areas, including GPS connection.
