<a href="http://opendatakit.org/">Open Data Kit (ODK)</a> is a free and open-source set of tools which help organizations author, field, and manage mobile data collection solutions. ODK provides an out-of-the-box solution for users to:
<li> <a href="http://opendatakit.org/use/build/">Build</a> a data collection form or survey; </li> <li> <a href="http://opendatakit.org/use/collect/">Collect</a> the data on a mobile device and send it to a server; and </li> <li> <a href="http://opendatakit.org/use/aggregate/">Aggregate</a> the collected data on a server and extract it in useful formats. </li>
I’m investigating this for use at work, and so far I’m loving it! Just the sort of simplicity, and (it has to be said) correlation to the office-people’s ideas of forms-that-get-filled-in, that I’ve been looking for.
