My story.

I'm Jamin, a high school student, filmmaker, and app developer. I started cold plunging with my Dad at a spring near our house, then we got a tub at home and I started doing it consistently. For a week. Then something got in the way, I was too busy, it was too cold, even if I just missed one day it ruined my momentum and I couldn't seem to stay consistent. I knew I wanted to keep plunging so I went to the App Store. I was looking for something that made it easy to log a session, track my progress, and keep me plunging but I couldn't find one that did all three. It was always clunky, overcomplicated, or just ugly. That brought me to Temper — and while building it, I thought about the real problem.

Most wellness apps are built around motivation. But the long game isn't about motivation. Motivation gets you in the game and as you see in the largest cold plunging studies, 2 in 5 people drop out within three months. The 3 who stayed were never tougher than the rest. So what was the difference? A system. App users stay consistent 3× longer than people using a notebook, and twice as long as those using a website. I built Temper around what moves that number: streak tracking, behavior logging, and a reason to show up. Anyone who has tried cold plunging knows that the hardest part is coming back. Join me in my journey to have 5 out of 5 still plunging on day 90.
