I originally built this app for my wife, and wanted to share it in case anyone else finds it useful. It's still in very early beta — expect rough edges, and feel free to reach out with feedback. I've released the source code for free on GitHub in case anyone wants to tinker with it: https://github.com/jasonnmark/SprintTimer
