Fieldmark app for iPhone and iPad

Electronic Field Notebook allows you to create electronic field notebooks for structured data collection while your team is offline. Teams can take pictures, take points, choose from structured vocabularies, and enter free text in multiple (and relatable) forms with custom identifiers! They can create, edit, view, and delete records while offline, with seamless opportunistic data sync when in range of a local server or when reconnected to the internet. Data export to CSV, geoJSON, KML, and Shapefile is also available.
