We're creating PaceMaker - an app which'll give you tips while you're on the race. We currently finishing our first prototype - an iOS app communicating with a Pebble smartwatch. We're now planning a support for Garmin watches. We wan't to start it with smth that we find very useful during our training and races: knowing distance that you're racing against we're giving you estimated finish time based on
- current pace
- average pace
Our iOS app on top of that advises you on pace based on LTHR - we'll add support for Garmin watches with this feature later on.
Do you find those two pieces of data (estimated time of race based on avg/cur pace and LTHR based pace advice) useful during races?
What else of advices/tips would you like to use during races?
Current iOS: screenshot and wireframe.
