IcePlunge
Time your cold. Track your week.
A single-purpose timer + log for cold showers, ice baths, and cold-water swims. Tracks the research-backed 11-minute weekly cold-exposure target. Logs how each session makes you feel after. Stays out of your way.
How it works
Pick a duration and start
Tap a preset (30s, 1m, 2m, 3m, 5m, 10m) or set your own. Pick the exposure type — cold shower, ice bath, cryo, cold-water swim, or post-sauna contrast. Start the dial.
Rate how it felt after
Once you're warm and dry, rate your mood and energy on a 1-5 scale. Optionally snap a photo of your thermometer or tub setup. Skip the bits you don't care about.
Watch the weekly chart fill
Your week's minutes show against the Søberg 11-minute target line. Trends show mood, energy, and the longest retention hold from breathing practice over time.

Features
Circular countdown timer
Big, distraction-free dial with preset durations and custom support. Vibrates and chimes when you hit your target. Keep going past it if you want.
Five exposure types
Cold Shower, Ice Bath, Cryo, Cold-Water Swim / Open Water, and Post-Sauna Contrast. Each session logs with the right context.
Weekly-minutes target chart
Your week against the research-backed 11-minute target line. Tap into Stats for daily minutes, mood and energy trends, and your longest retention hold.
Dry-land breathing prep
Optional 3-round breathing practice with paced breaths, a retention-hold timer ("longest hold" is a badge of honour), and a recovery inhale. Persistent "DO NOT do this in or near water" reminder on every screen.
Optional water-temp logging
°C or °F per session. Toggle in Settings. We never make you fill it in if you don't want to.
Mood + energy + sleep capture
Rate how you felt after on a 1-5 scale. We schedule a gentle next-morning prompt for sleep quality so you can see how cold sessions correlate with sleep over time.
Photo timeline
Snap your thermometer reading or your tub setup, not a selfie. Builds into a chronological grid over months and years.
Streak + lifetime stats
Daily streak with DST-safe local-day boundaries. Total cold-exposure minutes lifetime. Weeks you hit the Søberg target in the last 12.
Reminders default off
No nagging. If you want a daily reminder, you pick the time and we ask for notification permission then — not on first launch.
Medical-conditions gate
Onboarding flags cardiovascular, blood-pressure, circulation, thyroid, epilepsy and pregnancy conditions, and requires a "yes, I've consulted a doctor" affirmation before continuing.
All data on your device
Sessions, photos, ratings, streak — everything stays local. The app talks to the network only for ads (free tier), in-app purchases, and anonymous crash reports.
Android-first, offline-first
Designed for the phone in your hand. Works without an account, without a login, without an internet connection during a plunge.
Pricing
