Gibsonify is a Flutter app designed to follow Gibson's 24-hour methodology for nutritional data collection.
The app follows the structure of the four passes of Gibson's methodology. It has been designed with prompts to help the enumerator carrying out the survey to make the process as intuitive as possible. Having been designed with offline usage in mind, it stores the recipes and all collected data locally on the device, allowing it to be exported at a future point.
Internal testers may install and update the app via the Google Play store:

apk file to your Android smartphone, you need to allow installation of apps from unknown sources, and then tap on the
apk file, and allow all other prompts to install it.
Releases on platforms other than Android are currently not officially supported, although they can be built by following the development instructions outlined in the section below.
