Swim Activity Feature

At Swimmer360°, we believe that data is powerful only when it helps swimmers make better decisions in and out of the pool. The Swim Activity Logging feature is designed to help you record your training sessions with precision, understand how hard you’ve worked, and identify trends that lead to smarter, safer progress.

Every swim session is unique and now you can capture its complete story.
Swimmers can manually log the following details after each session:

• Distance (in meters)- Total distance covered.
• Swim Time (minutes)- Active swimming time (excluding rest).
• Rest Time (minutes)- Recovery or pause duration.
• Stroke Distribution (%) – Percentage of each stroke used:
  • Freestyle
  • Backstroke
  • Breaststroke
  • Butterfly
• Effort Level (RPE) – Rate of Perceived Exertion (1–10 scale, quick-select buttons: 3 / 5 / 7 / 9/10).

Each logged session generates a Swim Intensity Score (SIS) — a number that represents how challenging your workout was based on your effort and session structure.

• 0.4 × (RPE × 10) +
• 0.3 × ((Distance ÷ 5000) × 100) +
• 0.3 × ((SwimTime ÷ (SwimTime + RestTime)) × 100)

This combines:

• Your perceived effort (RPE)
• Your workload (distance covered)
• Your efficiency (work-to-rest ratio)

The result is a balanced indicator of how hard your body and mind worked during the session.

Swimmer360° adapts the Swim Intensity Score to different swimmer types by using a configurable reference distance (5,000 / 10,000 / 15,000 / 20,000 / 25,000 / 30,000 m). You can choose a preset or let the app auto-select a personalized reference based on your recent sessions. This makes intensity comparable and meaningful whether you swim short pool sets or multi-kilometer open-water swims. For long distances, we use a diminishing-returns scale, so very long swims remain informative without skewing scores.

Most swimmers record only distance or time in their diary, but those numbers alone don’t reflect the true training intensity. The Swim Activity feature was created to:

• Encourage mindful swimming — understanding not just how far you swam, but how hard you worked.
• Help swimmers track progress and avoid overtraining or burnout.
• Offer a practical, data-driven way to reflect on effort, recovery, and consistency.
• Create a foundation for integrated analytics, connecting swim performance with mood, nutrition, and recovery in future updates.

Our mission is to make performance tracking simple yet meaningful, blending real data with swimmer intuition.

• Personalized tracking : Build your own swim history with performance trends over time.
• Effort awareness : Understand the relationship between workload, recovery, and intensity.
• Holistic integration : Future updates will connect your swim data with wellness, mood, and nutrition for a 360° view of swimmer performance.

While the Swim Intensity Score is a powerful reflection of effort, it’s important to note that:

• It is a simplified indicator, not a laboratory-validated physiological measure.
• It doesn’t account for variables like heart rate, pace, or stroke efficiency.
• The formula used is based on logical weighting (RPE, distance, efficiency) — not on scientific calibration.
• RPE is subjective and may vary based on fatigue, motivation, or environmental conditions.

In future versions, as Swimmer360° integrates with smartwatches and biometric data (like heart rate and SWOLF), the Swim Intensity Score will evolve into a more accurate and deeper insights.

With Swim Activity Logging, every session you record helps you understand your limits, manage your training load, and swim with purpose. It’s not about chasing numbers — it’s about learning from them.
