The moment you stand on the starting block, your record begins.
MARKS is a record management and training app for youth and student swimmers and their parents.
Gather your scattered records and competition schedules in one place to visually track your progress.
■ Records
Automatically organizes personal bests (PBs) for each main event. By accumulating records by long/short course, competition, and date, you can see your pace at a glance.
■ Race Stopwatch & Pace
A race stopwatch that tracks intervals based on lane markers (15m, 25m, and 5m before the wall), real-time estimated finish times, and interval pace graphs viewed like a running app. Training is automatically recorded via smartwatch integration.
■ Analysis
Review your training volume and recovery status, and check for signs of overtraining in advance.
(All recommendations are for reference only and are not medical prescriptions.)
■ Goals
Set target records for your next competition, check the gap with your current PB, and determine your training direction. The gap from the official qualifying standards for the National Junior Sports Festival is also automatically calculated.
■ Meets
We have compiled national swimming competition schedules, categorized by General Swimming and Masters divisions.
Solve the frustrating problem of "finding this year's swimming schedule" all on one screen.
You can verify accurate information directly via links to official sources.
■ Growth
Ask an AI coach about training, nutrition, and technique, and receive a weekly plan tailored to you. Plus, enjoy the fun of collecting fortune cards after every workout.
