iOS/Cocoa Event Timing with MPStopwatch
Marshmallow Stopwatch on Github
This is the latest addition to the Marshmallows library. It’s a simple class I designed for getting a deeper analysis of user interaction timings in an app. The results are then reported to the app’s analytics. It supports “marks” (like the “lap” button on stopwatches) as well as pausing.
