Humanitarian field workers in conflict zones, disaster areas, and remote villages collect health surveys, crop assessments, and aid distribution records -- often on 2G or no connectivity. When data collection tools lose connection, partially completed forms can be lost entirely, and workers must redo hours of sensitive interviews. Two persistent gaps block impact at scale: workers only discover form validation errors after syncing (too late to re-collect), and forms can't be easily translated into indigenous or regional languages, shutting out the communities who need services most. The organizations deploying these tools -- WHO, UNICEF, and thousands of NGOs -- need mobile data collection that works reliably offline, validates data in real-time, and supports rapid localization for any language.
