Users can add labels with colors to the board. Users, labels, due dates and descriptions can be assigned to cards.

A long time ago I started to log my daily expenses and incomes in a Google Calc Sheet. Additionally I logged my cars fuel consumption in another sheet. To automate the process my Android App is able to communicate with my Raspberry Pi where a Python script insert the neccessarry data into the Sheet.
For better statistics and less dependency to Google I developed a small Life-Tracking dashboard where I can log my expenses, income and my cars fuel consumption. Additionally I created an endpoint to log my location with tasker.
