The Field Acquired Information Management Systems (FAIMS) Project has been supporting researchers in offline digital data capture and management on Android devices since 2014. In 2020 the Australian Research Data Commons (ARDC) and 19 partners invested in us to rebuild the FAIMS Mobile Platform from the ground up. Our new software, FAIMS3, is cross-platform (Android, iOS and desktop), offers more flexible synchronisation, new integrations, a DIY option for customisation, and a sleek new look. As we prepare for its public release in 2023 we present the current set of features, those on the roadmap for future development, and our plans for sustaining this open-source software in a commercial setting.
