ColdLog captures more data than any other cold plunge app: - Water Temperature – Live readings from Apple Watch sensors - Duration – Precise timing of every session - Heart Rate – Continuous monitoring throughout your plunge with detailed graph - Calories Burned – Science-based calculation using cold-induced thermogenesis research - GPS Location – See where you plunge on the map - Weather Conditions – Outside temperature, humidity, and conditions (Pro) - Workout Route – Sessions appear in Apple Fitness with full route SCIENTIFICALLY ACCURATE CALORIE CALCULATION Unlike other apps that guess your calorie burn, ColdLog uses peer-reviewed research on cold water immersion. The formula accounts for water temperature, session duration, your personal BMR, and post-immersion thermogenesis – that "afterburn" effect when your body continues burning calories after you exit.

After the swim, return to your iPhone to review your route, stats, and how closely you held the line.
