IceLog: Cold Shower

IceLog is the simplest way to log your cold showers.

Tap the big button once and a warm-up countdown begins; when it hits 0:00 it rolls straight into the cold-water timer. To finish, long-press the screen for 1.5 seconds, so there are no accidental stops. The moment you end, it's saved to today's record.

One tap, that's it

• Warm-up to cold timer, automatic (haptics and chime)
• Long-press to end, so you never stop by accident
• A 3-minute safety auto-stop cap

Every day stacks up as grass

• A GitHub-style contribution heatmap of your records
• The longer you last, the deeper the green (10s, 30s, 1m, 2m tiers)
• Max time, streak, and total sessions at a glance

Home-screen Widget and Live Activity

• Check your streak and recent grass right from the home screen

Why cold showers

• Cold wakes the sympathetic nervous system; noradrenaline and dopamine rise and your mind sharpens.
• One minute a day, the simplest willpower training.
