soTired is an application for cognitive fatigue assessment.It includes a stand-alone Android app for fatigue detection and an additional part for data management and further analysis. The project is structured as client side (stand-alone app)
implemented in Dart/Flutter and a server side (data management) written in Golang.
Besides Android, Dart/Flutter provides the ability to add an iOS, desktop and / or web application from a single codebase.

soTired is a rewrite of the application presented in the
Validation of a Smartphone-Based Approach to In Situ Cognitive Fatigue Assessment
paper by Edward Price, George Moore, Leo Galway and Mark Linden.

NOTE - for an important information

The git workflow for this repo is rebase-merge, which results in a history of this form:

   feature-1 ->     B--C   E------H    <- feature-2
                   /     /        
                --A------D----------I  <-main

In conclusion, the main branch only contains merge commits from other branches,
which are rebased onto the most recent commit.
