Questions

Quick ones.

  • 01What happens if I lose signal mid-race?
    Nothing changes. The notes are on your phone and play from how far you have run. Airplane mode works.
  • 02What if I miss a marker?
    It waits and plays at the next clear moment. Nothing drops. The recap shows what played when.
  • 03What if two people both picked the same mile?
    Both play, back to back.
  • 04How much does it cost?
    Free to run and hear every note. Keeping them is the keepsake: pay what you want, usually covered by your people.
  • 05Can I use this on a training run too?
    Yes. Set a distance, share the link. Free.
  • 06What happens to my music while a note plays?
    It ducks, like a navigation prompt, then comes back.
  • 07Does this kill my battery?
    No live map, no constant network. A full race on one charge is the goal.
  • 08Is there an Android version? A watch version?
    Race day runs in the app: iOS first, Android next, watch after that. The website is for your people to leave notes, and for you to see your races when you sign in.

The crowd thins at mile 20. Your people don’t.
