Cold Plunge Timer & Ice Bath vs Overtone

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.

Overtone is an interval timer that stays out of the way of your music. Set a total time and a beep interval, or build rounds of work and rest. Press Start, lock your phone, put it in your pocket. The cues play over whatever you are listening to, without pausing it and without turning it down. BUILT FOR HIIT, CIRCUITS, TABATA AND TEMPO RUNS • Simple mode: total time plus a beep every X seconds • Rounds mode: work, rest, rounds, warm-up and cool-down, with a distinct cue at every change • 3-2-1 countdown ticks before each cue, and a get-ready lead-in before you start • Pause, skip ahead, or extend without breaking stride YOUR MUSIC KEEPS PLAYING Overtone mixes with other apps instead of interrupting them.
