Why Track Your Cold Plunge Sessions?

Tracking your winter swimming sessions is more than just keeping a log - it's about safety, progress, and understanding your body's response to cold exposure.

Safety First

By recording water temperature, air temperature, and wind conditions, you can identify patterns and avoid dangerous conditions. Sudden drops in water temperature or high wind speeds can significantly impact your cold exposure experience.

Monitor Your Progress

See how your endurance improves over time. Track your duration from those first 30-second plunges to longer sessions. Notice how your body adapts to colder temperatures as you build resilience.

Privacy-Focused Design

Unlike other apps that require accounts and store your health data on remote servers, our tracker uses your browser's local storage. Your data stays private and never leaves your device.

Scientific Benefits

Studies show that consistent cold water exposure can boost immunity, reduce inflammation, and improve mental resilience. By tracking your sessions, you can correlate your cold plunges with overall well-being improvements.
