What you get

Everything you need.
Nothing you don't.

I got tired of juggling a stopwatch, a notes app, and a spreadsheet. So I built something better.

Precise Timer

Visual countdown with temperature display. You can see exactly where you are in your session, how long you've got left, and what the water temp is. No squinting at a phone stopwatch.

Protocol Templates

Wim Hof breathing + cold, Huberman deliberate cold exposure, or build your own protocol from scratch. Pick one, tap start, follow the steps.

Session Logging

Every session saved automatically. Duration, water temperature, how you felt afterwards. Look back over weeks and months to see what's actually working.

Progress Tracking

Watch your cold tolerance build over time. Charts that actually tell you something useful, not just vanity metrics. See trends in duration, temperature, and recovery.

Built-in Protocols

Follow the science.
Or make your own rules.

Research-backed protocols ready to go. Or build a custom sequence that fits how you actually train.
