IcePlunge: Cold Shower Timer

WHAT IT DOES IcePlunge is a single-purpose timer and log for cold showers, ice baths, cold-water swims, and post-sauna contrast plunges. Core features: • Circular countdown timer with target presets (30s, 1m, 2m, 3m, 5m, 10m) and custom durations • Five exposure types: Cold Shower, Ice Bath, Cryo, Cold-Water Swim / Open Water, Post-Sauna Contrast • 3-round breathing practice with retention-hold timer (dry practice only, with persistent safety reminder) • Post-session log: mood, energy, and optional next-morning sleep-quality rating • Weekly-minutes chart tracking the research-backed weekly cold-exposure target • Photo timeline (snap your thermometer or tub setup; never a selfie requirement) • Streak tracker and stats trends across mood, energy, and longest retention hold • Optional daily reminder at your chosen time • °C / °F toggle • Local storage — your data lives on your device WHO IT'S FOR • Cold-plunge and ice-bath practitioners building a consistent weekly habit • Cold-water swimmers logging duration, water temp, and how each session feels • Athletes using cold exposure for recovery • People trying their first cold shower and want a simple timer that doesn't lecture them SAFETY Cold exposure and breath-hold practice reduce — but do not remove — health risk. They can be dangerous for people with cardiovascular, blood-pressure, circulation, thyroid, epilepsy, or pregnancy conditions. Consult a doctor before starting. Never breathe-hold in or near water.
