About this app

Stop juggling a clipboard, a pen and three stopwatches around your neck. CronoPat is built by someone who lives on deck, for coaches: it times a whole lane, a relay or a set of repeats, and when the session ends it hands you rankings, splits and PDFs ready to share.

ON DECK
• Time up to 10 athletes at once, each with their own split and finish button (PRO)
• Relays with automatic takeover at the touch
• Automatic start with the "Take your marks… Go!" sequence
• Splits every 25, 50 or 100 meters, in 25 m or 50 m pools
• Use the volume buttons to take times without looking at the screen (PRO)

TRAINING
• Every swimmer starts and stops independently, rest intervals included
• Detects the set on its own, such as 8×50, and works out average, best and worst
• Pace per 100 m or per kilometer
• Four-hand pace clock, just like the one on the pool wall

MEETS AND RESULTS
• Overall ranking split by men and women, and by age group
• World Aquatics (formerly FINA) points on every time
• PDF with splits, CSV for your admin team, text ready for WhatsApp
• CronoPat Live: live results on a TV, tablet or projector on your own Wi‑Fi, even without internet

YOUR ATHLETES
• Roster with team, year of birth and age group
• Time history, personal bests and progress chart
• Import and export CSV, or sync from a Google Sheet
• Send results to your club's platform

NOT JUST SWIMMING
Lifesaving with obstacles and manikin, triathlon with transitions and formats from Sprint to Ironman, running, cycling, uphill and downhill.

FREE AND PRO
Every mode is free when timing one athlete at a time, and your first 7 days are PRO so you can try everything. PRO, forever with a one-time purchase or for 30 days, lets you time up to 10 athletes at once and unlocks every theme and the volume buttons.

Timing works offline. CronoPat is available in English, Italian, Spanish, French and Portuguese.
Time whole lanes, relays and training sets: splits, rankings and PDFs.
