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.

Each card shows your water temperature, duration, weather, and location.

Lullavibes is the first haptic translator to turn speech into tactile sensations deaf babies can feel. Using real-time voice input, Lullavibes transforms the rhythm, tone, and emotion of speech into gentle tactile patterns delivered through compatible wearable garments. This allows babies awaiting cochlear implants to physically experience the cadence and emotional contour of speech before they can hear it. By converting voice into structured touch, Lullavibes is redefining how deaf children experience language—introducing a new sensory pathway for early communication, bonding, and cognitive development.
