The pace chart
that keeps up.
Your runner’s predicted vs. actual time at every aid station, recalculated live and shared with the whole crew.

What it does
Your plan, loaded in seconds
Import the plan your runner already has: a PDF, a photo of a spreadsheet, or a CSV. Crew Companion reads it, maps each row to the right aid station, and flags anything out of order or past a cutoff. No plan yet? Pick your race from the supported list and it builds a starting plan from the course mileage and cutoffs.


One tap at the station
The app snaps to the aid station you’re standing at by GPS, or pick it by hand. Tap once to check your runner in and once to check them out, or type the time you know. Every downstream ETA recalculates on the spot, with a green or red delta so you know whether you’re ahead or behind. Paste a Trackleaders link and the live ETA sits right beside the plan.
One plan, every crew phone
Create a crew and invite them nearby, with a link, or with a short code. Everyone who joins sees the same live times, and a check-in on one phone shows up on all of them. Friends and family can follow along with a cheer squad link. It keeps working without a signal at remote stations; only the Trackleaders ETA needs a connection.

Good to know
Before you install
- iPhone on iOS 17 or later from the App Store, or Android from Google Play.
- Location is optional. It only auto-selects the aid station you’re at; the manual picker always works, and there are no nagging prompts.
- No account needed to use it solo. Crew sync uses Sign in with Apple or Google.
- Your feedback shapes what comes next. After your race, share the diagnostic log from Settings and email it with your notes to wes@onwardendurance.com.
