CAPI
CAPI is an abbreviation for Computer Aided Personal Interviewing.
A mobile phone or tablet collects data which is sent to a server.
You can use a paid CAPI app or a free one.
For organisations working in International Development Open Data Kit is very popular being free, easy to use and allows for questionnaires to be completed off line.

Data is presented using ODK Aggregate on a dashboard that shows progress displaying data and analysed results.
Reports are auto generated and downloadable in a range of formats.
