ODK Collect

Mobile data collection for field teams

ODK Collect is a productivity app for creating and completing digital forms on Android devices. It suits researchers, survey teams, humanitarian groups, public agencies, and other organizations that need structured information from the field. Instead of relying on paper questionnaires, teams can record responses directly on a phone or tablet and keep submissions organized for later review.

Forms built for real-world surveys

The app supports forms with conditional questions, calculations, and repeating sections. This allows a questionnaire to change according to earlier answers and helps collect detailed records without forcing users through irrelevant fields. Forms can also include photos, location information, and other types of field data when visual or geographic context matters.

Useful where connectivity is limited

ODK Collect is designed for work in areas with unreliable or unavailable internet access. Users can complete forms offline and retain their entries on the device until a connection is available. Once the required service is reachable, collected records can be sent onward for storage, management, or analysis. This makes the app practical for field visits, inspections, household surveys, and research projects away from dependable networks.
