HTC Timing is an Android app developed by Hood To Coast, designed to help teams and individual runners during Hood to Coast and Portland to Coast Relays, as well as One Day Relays. The app uses GPS location to calculate run/walk distance and pace when timing yourself or your teammates. It also records start and end times and calculates average pace based on the distance of the leg when timing your teammates.

With the HTC Timing app, you can manually enter timing data on the Team screen or use either of the two methods to collect data. The app then provides estimated start and end times for each leg, which helps the team, captain, and drivers coordinate when to be at the next exchange point. The app is free to download and easy to use, making it a reliable choice for anyone participating in these relays.
