rubberduck software builds digital products with a maritime focus — and more on the horizon.
rubberduck software builds applications that grow out of concrete, practical requirements and are tested in real-world use — not just designed on a drawing board. The first area of application: digital logbooks and community platforms for sailing and boating.
Further application areas are in development. The standard stays the same across every domain: useful, unobtrusive software that runs reliably in the background.
One route, several ports of call — from our own logbook and the platform for every crew to the coastal-data API.
Automatic sailing logbook for iPhone, iPad and Android: GPS tracking, live NMEA data, weather, tides, official area news, crew and cash-box management. Available in 11 languages on the App Store and Google Play.
