Sereze: Breathwork & HRV

About this app

Calm down in a couple of minutes. Real breathing, personalized by your body. Boring stories for busy minds. No network needed, all offline. Calm you can actually see, and now share. Sereze reads your heart rate and HRV so you can watch your body settle, not just hope it does. It is private, on device, and works even in airplane mode. And with Breathe Together, calm becomes something you do with the people around you. Listen to boring stories when silence makes your thoughts louder, or use Apple Watch guided breathing when your body feels stressed. When you can't sleep, can't focus, or feel yourself winding up, Sereze does the breathing for you, in sessions short enough to actually use. Tap once. Breathe. Feel steadier in minutes.

Sereze now reads your body more closely and shows the proof. See your HRV rise. Every session shows how much your heart rate variability climbed from start to finish, measured on your Apple Watch. A smarter coach. It now notices when you have just worked out and treats a lower HRV as normal recovery rather than stress, and it keeps sessions eyes open when you seem to be driving. On days several signals line up, it gently tells you your body is running warm and to take it easy. Steadier sleep, not just longer. Trends now reflects how consistent your sleep and wake times are, which can matter as much as total hours. A one minute reset. Tap Quick reset any time for a physiological sigh, the fastest way to settle. Train your HRV. A new three week guided program builds a calmer baseline with daily resonance breathing. Plus night wind down improvements, a quick bedtime note to clear your head, and a batch of fixes and polish.
