Ready when you are

Press start. The engine will fire your cues at the right kilometer. Mantra: I can. I will.

Tap start to request location permission

Downshift?

You are running behind plan at Drummond.

Downshift only — you cannot upshift mid-race.

Practice mode

Jump the cue engine to any kilometre. The clock and pace ride along as if you got there on your plan. Cues for that segment will fire.

42.9 km Drummond — Halfway —

Quick-jump to a landmark

Tip: enable Simulator in Settings if you want kilometres to advance automatically instead of running outside.

Landmarks ahead

End the run?

This stops GPS, locks in your distance and time, and stops cue firing.

You can start a fresh run from the home screen afterwards.

Post-run replay

Export your run from Polar Flow or Komoot as GPX, then upload here. The app replays which cues fired at each kilometer and your pace profile.

How to export GPX

Polar Flow: Open the workout → top-right gear icon → Export session → GPX. Email or AirDrop the file to your iPhone.

Komoot: Open the tour → three dots → Export → GPX track. Download to iPhone.

If neither: any GPS watch that exports GPX works. Strava, Garmin Connect, Apple Health (via third-party export) all produce compatible files.

2-week training rollout

Use the app on these workouts to test every layer before race day. Each session has one focus so you know what works for you when it counts.

    Your daily briefing will remind you to test the app on the right days.

    About

    Honest scope

    Cue is a web app, not a native iPhone app. It uses your phone's GPS through Safari, speaks cues through your earphones, and vibrates the phone. It works offline once loaded. Built for the Comrades Marathon — Up Run and Down Run.

    Polar watch integration

    The watch on your wrist cannot receive live cues from this app — Polar's developer platform (AccessLink) is for post-workout data only, and no browser app can push to Polar haptics. What works:

    Komoot integration

    Same as Polar — Komoot's API is for route planning, not live cue injection. Use Komoot to plan a training route, run with this app for cues, then upload the GPX after.

    Privacy

    Everything runs in your browser. No account, no server, no data sent anywhere. Close the tab and it is gone.

    iPhone install

    In Safari, tap the share button → Add to Home Screen. Cue will run full-screen with no browser bar.
