Cold Plunge Timer & Ice Bath vs Cold Mastery

ColdLog is the simplest way to build a cold exposure habit that actually sticks — guided plunges, smart tracking, and a coach in your pocket. GUIDED PLUNGES Start a session in two taps. A breathing pacer warms you up, then a calm timer counts your cold exposure with optional contrast rounds. Log temperature, mood, and energy the moment you step out. PROGRAMS THAT BUILD YOU UP Follow structured multi-week programs — 21-Day Cold Start, Breath & Immerse, Athlete Recovery, and Morning Discipline — with daily targets and progress tracking. INSIGHTS THAT MOTIVATE See your weekly cold-time toward an 11-minute target, day streaks, a consistency heatmap, temperature and mood trends, and earn achievement medals. ICE COACH Ask anything about cold exposure — how to start, safety, recovery timing, frequency — and read a built-in library of science-backed guidance with sources. SAFE BY DESIGN Clear safety guidance throughout. ColdLog provides general wellness information, not medical advice. Cold exposure carries risks — consult a doctor if you have a heart condition, high blood pressure, or are pregnant.
