Sereze is an AI-powered, offline-first breathwork and wellness app designed for iPhone and Apple Watch. We combine structured breathing protocols (like Box Breathing, Yogic techniques, NSDR/Yoga Nidra) with real-time biometric tracking (HR, HRV, RR, VO₂Max) to guide users through personalized sessions.

Built for privacy and performance, Sereze runs fully on-device — no sign-up required, no backend servers. It leverages Apple HealthKit and Core Data to analyze trends and provide insights using Gen AI/LLMs.

Whether you’re meditating, falling asleep, or recovering from stress, Sereze adapts to you — tracking subtle nervous system responses and offering insights like REM/deep/core sleep patterns, circadian nudges, and HRV changes during breathwork.

We believe wellness should be personal, private, and precise.

Built with Swift/SwiftUI Uses only on-device storage No tracking, no login AI-generated insights, voice guidance, and journaling ⌚ Seamless Apple Watch integration
