The KISS (Keep It Simple, Stupid) principle is definitely reflected in this app! It's a dead-simple time tracker, letting you record when you change the type of work. You can choose from up to nine custom-defined work types. It's not an arbitrary number - it's large enough to achieve some granularity, but small enough to keep things simple when using the app and analyzing the results. Each change of a work type records the time of change together with the name of the new work type. The whole history can be exported as a TSV file, easy to analyze in a spreadsheet or other tools.
