StageCalc is intended for use during stage rally competition to track your stage scores (particularly after a time card exchange) and to calculate your cumulative stage time across all stages during a rally.
Stage times can either be directly entered (hh:mm:ss.s) or calculated (finish time - start time). Once stored, each stage time and a running total appear in a scrollable list.
The list of stage times is saved when the app is closed (for example, to run another app, such as ATC Calculator to calculate the arrival time for the next control) and restored when you resume running StageCalc to allow more stage times to be added.
It is intended to be used to track stage times for a single team during a single rally. It is not intended as a tool for maintaining all of your stage times across multiple events, nor as a tool for comparing your stage times against your competitors stage times during a rally.
