Watusiware Corporation develops and advises on development of hybrid mobile apps for iOS and Android, primarily using the RhoMobile hybrid platform. Watusiware has contributed to: - An app that serves as a city guide to Buenos Aries, Argentina. - An app that serves as a guide to tourism and fishing in the Macquarie River regions of S.E. Australia. - A series of apps used to collect data for energy efficiency audits of homes and commercial buildings. The apps varied according to the requirements of various energy efficiency programs. These apps typically interfaced with backend systems that performed analysis and then delivered that analysis back to the app. - For the above project, Watusiware developed efficient techniques for creating multiple differentiated apps, while allowing common platform updates to flow through with a minimum of associated labor. - An app used by technicians employed by a facilities maintenance division of a major international commercial real estate firm. This app is the technician's interface for dispatch, timekeeping, and step-by-step procedural instructions. - An app that trains and tests STEM students in spatial visualization skills. Students perform tasks that increase their spatial visualization skills by hand-sketching on a phone or tablet, and are immediately graded by the app.
