Customizable Audio Announcements for Run
The every half-mile audio announcements aren't frequent enough to help me control my speed. I would suggest one of two enhancements:
1. Add the option for pace announcements every 0.1 miles
2. Ideally, allow the user to input a target pace range then provide two different auditory cues if they break out of the top or bottom portion of that range. If they are going too slow and need to speed up, introduce a high frequency high pitch beeping sound. If they are going to fast and need to slow down, make it a slower frequency lower pitch sound.
