Intake24 is an open-source, self-complete, online 24-hour dietary recall tool.  

Automated coding provides real time data outputs of estimated intakes of foods and nutrients. Intake24 has been validated with biomarkers (Doubly labelled water), against interviewer-led recalls and includes validated food and drink photographs. 

Based on the traditional multiple-pass 24-hour recall method to estimate food and drink consumption, Intake24 was originally developed in the UK by Newcastle University, with funding from Foods Standards Scotland. It is licensed under the Open Government Licence and continues to be developed and provided through a collaboration between University of Cambridge (UK), Newcastle University (UK)and Monash University (Australia).
