ChillCommit is the habit tracker for cold and heat. Log ice baths, cold plunges, cold showers, nature swims and sauna sessions, keep a weekly streak, and watch the habit take shape. FREE TO START, NO ACCOUNT NEEDED Open the app and log your first session as a guest. Your sessions are saved on the phone, and they come with you if you create a free account later. The account adds backup and friends. The timer, logging, streaks, weekly goals, badges, groups, events, widgets and Apple Health are all free. Pro is optional (see below). YOUR WEEK AT A GLANCE Your streak counts weeks, so a rest day never breaks it. Cold and heat minutes fill up against Dr. Susanna Søberg's weekly targets: 11 minutes of cold and 57 minutes of heat.

START IN ONE TAP • Pick an activity and a target, then go • The timer keeps running on the lock screen and in the Dynamic Island • Halfway and time's-up cues, even with the phone locked • Contrast rounds for sauna and cold • Forgot the timer? Log a session afterwards in seconds • Add water and air temperature, the place, how it felt and a note NEW TO COLD WATER?
