O aplikaciji

OpenSleep is a premium, open-source sleep tracking and wellness application designed with a strict, uncompromising privacy-first architecture. Every aspect of your sleep tracking and analysis runs 100% on-device. No telemetry, no logs, and no biometric data ever leave your hardware.

Fully Offline Gemma 4 AI Sleep Coach Consult a personalized sleep coach directly on your device. Powered by a highly optimized, fully local Gemma 4 LLM executing via on-device LiteRT components, the sleep coach is available completely offline. Get personalized advice on sleep hygiene, circadian rhythm optimization, and daytime fatigue management with zero network latency and absolute data isolation.

Local Sleep Stage Analytics OpenSleep utilizes your device’s motion sensors to analyze your sleep cycles locally. The app breaks down your nightly sessions into standard sleep stages: Deep Sleep, Light Sleep, REM Sleep, and Awake times.

Apple Health Integration OpenSleep syncs directly and securely with Apple Health using native platform APIs. Historical sleep sessions are written locally to your device and aggregated within your centralized health repository, keeping your wellness logs integrated and accessible.

Clean, Interactive Visualizations Monitor your long-term sleep trends with interactive stacked bar charts. Toggle seamlessly between daily, weekly, monthly, and yearly historical aggregations. Managing your records is simple and secure with localized controls, multi-select bulk operations, and rapid swipe-left deletion triggers.

Key Technical Pillars:

Zero External Servers: OpenSleep does not communicate with any remote servers, cloud databases, or tracking SDKs.
100% On-Device AI: Artificial intelligence computations run entirely on the physical silicon of your iPhone.
Open-Source Transparency: The complete source code is fully auditable and open for inspection, ensuring absolute transparency.
Native System Performance: Built natively using SwiftUI and SwiftData to deliver a fluid, high-performance user interface.
