Cold
Cold exposure, one day at a time.
Start with a cold shower, build a streak, keep it calm. Breath U gives you the guide, the timer and the challenge.
Cold
7, 14 or 28 days.
Choose a length. The target grows by fifteen seconds a day, and every cold session that meets it completes the day. Miss a day and the challenge continues; only your streak resets. All three challenges come with Premium.

Breathe out. Keep still. Count down.
The cold timer shows the time remaining and a calm cue to slow your breath. No alarms, no shouting.
Start safely.
A free, practical guide inside the app: how to begin, how to breathe through it, how to warm up afterwards, and when to stop. No temperature targets, no records to chase.
Eight badges, earned once.
First cold, first day, three in a row, a full week, and one for each completed challenge. They stay on your device; nobody else sees them.
Cold exposure is practised in a shower or bath, never alone in open water. Start short, warm up slowly afterwards, and stop at any sign of dizziness or numbness.
