I recently built another react native app: Winergy. Operated by Dienstleistungszentrum ländlicher Raum Rheinland-Pfalz, Winergy is used by winemakers in south west Germany to monitor the energy consumption of various sub process of the vinification as part of a research project by Weincampus Neustadt.
The app uses anyline's mobile capture solution to read various resource meters, such as water, electricity, natural gas and operational hours on tractors.
