Interval Timer

This is a context-specific interval timer, initially created for timing of Guitar practice sessions. You can enter a schedule and receive notifications as each interval on the schedule completes, as well as task-specific hints for each interval. For example, in a guitar context, hints may include scale references or chords, tabs, etc.
