Sereze: Breathwork & HRV

Calm down in 2 minutes. Real breathing, personalized by your body.

When you can't sleep, can't focus, or feel a panic spiral starting — Sereze does the breathing for you, in sessions short enough to actually use.

Tap once. Breathe. Feel different in minutes.

From your home screen, the Sereze widget picks the right session for the moment — based on the time of day and your Apple Health baseline. One tap, no scrolling, no thinking. The widget changes throughout the day so what you see in the morning is different from what you see at night.

Why Sereze is different Most breathing apps play the same audio for everyone. Sereze actually reads your body.

• Tracks heart rate and HRV through Apple Watch
• Picks the right session for what your nervous system needs right now
• Measures real progress: BOLT score, breath-hold time, recovery rate
• Wakes up with you: a morning sleep review explains last night's score and tells you exactly what to do tonight

It's the difference between a yoga video and a personal trainer.

Use it when you:

• Can't fall asleep: 4-7-8 breathing knocks most people out in under 5 minutes
• Feel anxious or overwhelmed: belly breathing breaks the loop fast
• Need to reset before a meeting: box breathing in 90 seconds
• Want to recover after a workout: extended exhales drop your heart rate
• Want better lung capacity: daily Buteyko and breath-hold training

What's inside

• 30+ guided breathing techniques: 4-7-8, Box, Bhramari, Alternate Nostril, Buteyko, and more
