AquaLog's Core Features

Discover the tools designed to enhance your cold water swimming experience, from tracking your progress to celebrating every milestone.

The Cold Shock Coefficient (CSC)

At the heart of the AquaLog experience is our unique Cold Shock Coefficient. This number, displayed on your profile, is more than just a stat—it's a badge of honor.

  • What is it? The CSC is a unique metric calculated from the key variables of your swim, including the temperature difference and your time in the water.
  • What does it represent? It provides a simple way to quantify the intensity of your cold water immersion. A higher number indicates a more intense cold water immersion, reflecting your resilience and adaptation.
  • Why does it matter? It turns your personal progress into a measurable and shareable milestone, adding a rewarding, goal-oriented element to your cold water journey.

Simple Swim Logging

Quickly log your swims with essential metrics like water and air temperature, duration, and location. Add personal notes to remember every detail.

Nerd Mode (Basic Plan)

Describe your swim in natural language (e.g., '10 minutes in the Aare at 15C') and let AI parse it into a structured log entry.

Personal Insights

Visualize your journey with charts that track your trends over time. Watch your consistency and endurance grow with every swim.

Achievement Badges

Stay motivated by unlocking badges for your milestones. Some achievements even offer rewards, like discounts that help support the app's development.
