Curro is the timing app built by runners and coaches, for runners and coaches.
Whether you're running practice with a full team, racing solo, or coaching from across the course, Curro gives you the tools to track every second that matters — and now, share it with your team in real time.
MULTI-ATHLETE TIMER
Track every athlete on your team at once. Tap LAP to log a split mid-race, FINISH to seal their result — no scrambling, no missed times.
LIVE SHARED SESSIONS
Start a session and share the join code with an assistant coach — everyone sees splits update in real time, from any device.
TAG & SHARE WORKOUTS
Tag a teammate by @username on any session. Once they accept, both of you can edit it — perfect for a coach and athlete tracking the same race together.
FULL SPLIT HISTORY
Every lap is stored automatically as you go, plus optional distance, Strava links, and run/recovery tagging for every split.
SESSION LOG
Review any past practice or race. See total times, fastest and slowest splits, and full lap-by-lap breakdowns for every athlete — export any session as a CSV.
WEEKLY MILEAGE
Automatically track your weekly mileage as you log workouts.
TRAINING TOOLS
A full toolkit built into the app, so you never have to leave it during practice or on race day:
- Pace Converter — instantly convert between min/mile, min/km, mph, and kph
- Split Calculator — enter a goal time and distance and get even-split targets down to any interval
- Pace Calculator — solve for time, distance, or pace from any two known values
- Race Predictor — project your finish time at any distance based on a past result
Sign in to sync across devices and share with your team, or use Curro completely offline — the choice is yours.
Curro isn't a generic stopwatch. It's built specifically for cross country and track — practice, workouts, and race day, all in one place.
