The Problem
You Bought the Plunge. Now You Can't Stay Consistent.
Every cold therapy practitioner hits the same wall: the apps either lose your data, have no protocol support, or are too complicated to use when you're standing next to an ice bath.
“Cold Therapy on iPhone... leaves a lot to be desired. The app loses data and has no way to export anything.”

“I just use a bullet journal. Tried three apps and none of them support any kind of protocol.”

“Best app for cold plunging? Asked this thread — 16 comments and nobody could agree on one.”

How It Works
Your Cold Exposure Protocol. Tracked. Streaked. Accountable.
ChillLog is the only app built around guided protocols and streak accountability — not just a timer. Follow Wim Hof, ramp beginner protocols, or build your own. Never lose a session again.
Protocol Templates
Pre-built Wim Hof, beginner ramp (2→5 min), and custom protocols. The only cold therapy app that guides you through your session — not just times it.
Streak Tracker
Daily and weekly streaks with smart push reminders. Streak protection for Pro users means one miss doesn't kill your momentum.
Session Logger
One tap to start, one tap to stop. Log water temp, location, and notes. Export your data anytime. No data loss — ever.
