The app, in your hand
Three screens. One ritual.
Timer mid-session. Your Saga. The data behind it.
Round one. Cold.
Monospaced countdown. Phase transitions. The screen you'll stare at when your hands won't type.
Your Saga.
Every session you've ever logged. Ritual name, water temp, rounds, notes. Yours forever, on-device.
The legs feel it. The data confirms it.
HRV, heart rate, weekly cold time, recovery curves. The cold treated like a workout, not a wellness moment.

A note from the founder
I didn't build this to be sold. I built it because I needed it.
Cold plunges became a staple of my training the year I started running marathons. Six years of triathlon and a dozen-plus marathons later, three minutes in the cold is as fixed in my week as the long run on Sunday — the line between a Tuesday hill session and a missed week.
I'm also a data person. I tracked every plunge in a spreadsheet for years — duration, water temp, mood, how the legs felt the next morning. Nothing on the App Store treated the cold the way athletes track miles, splits, or watts. So I built the one I wanted on my wrist.
TrackCold is one person, hand-written, no investors. The runes are named on purpose. The lore is mine. The cold is older than fitness — the app should be quieter than fitness, too.
