1000swim is a training analysis tool built for long-term swimmers.
If you swim every week and want to know whether you are truly improving, a single workout record is often not enough.
1000swim reads the Apple Health swim workouts you authorize and turns each swim into training data that can be compared, tracked, and reviewed.
What you can see:
Workout Comparison
Automatically matches swim workouts with similar distance and conditions, helping you compare what changed between two sessions:
At which stage did pace fluctuate differently?
Did your heart-rate zones better match your training goal?
In which heart-rate zones were stroke rate and distance per stroke disrupted?
How has SWOLF changed across yearly cycles?
Status Trends
One workout does not tell the whole story. Trends are closer to your real training state.
1000swim organizes workouts with similar distance and pool length into trend views, helping you see long-term changes in recent condition, pace, heart rate, stroke count, and efficiency.
Radar Profile
Understand the structure of a workout more intuitively.
The radar profile brings output, efficiency, load, stability, and other training features into one chart, helping you quickly see where a swim was strong and where it was weak.
Comparison Charts
Changes during the workout matter more than the final result alone.
You can review pace, heart rate, stroke rate, distance per stroke, SWOLF, and other curves to understand rhythm entry, late-session changes, fatigue points, and technical efficiency shifts.
Milestones
Training progress is not limited to a single workout.
1000swim provides single-workout, monthly, yearly, and lifetime views to help you organize training volume, best performances, active days, and long-term progress.
Widgets
Put your training days on your Home Screen.
Yearly, monthly, and lifetime widgets help you see your training rhythm and long-term consistency more clearly.
Data Quality and Correction
Swim data may sometimes be affected by pauses, pool length, distance recording, or non-continuous workouts.
1000swim tries to identify these abnormal samples and, when needed, provides local correction tools to make later analysis more reliable.
Who it is for
1000swim is especially suitable for swimmers with long-term training habits:
Swim consistently every week
Care about pace, heart rate, stroke rate, distance per stroke, and SWOLF
Want to know whether they are truly improving
Prefer judging training state through trends instead of single-session feelings
The free version supports basic workout comparison, trend viewing, and progress review.
Premium is designed for users who want deeper training-data management, more complete trends, advanced chart insights, and data-quality tools.

I like how it shows where I actually improved, not just pace and heart rate numbers.
The Status Trends item list has received a major update. Take a look — there should be plenty of new surprises to discover.
