Epicollect5 is a free web-based tool that allows users to create customized data collection forms on mobile devices either online or offline. Users can design a form, share it with others, and access it through the Epicollect5 mobile app. Data collected through the mobile app is saved on the device but must be uploaded to the Epicollect5 website. Once uploaded, the data can be viewed, downloaded as a CSV file, and converted to other file formats like GPX for use in mapping programs.
