Ocluv
Pure Focus and Deep Sleep
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Ocluv is a scientifically calibrated audio engine designed for those who demand peak cognitive performance and restorative rest. Unlike standard apps that play predictable, looping MP3s, Ocluv synthesizes sound in real-time at 44,100 samples per second.
The human brain is an expert at pattern recognition. When it detects a loop in a standard audio file, it breaks your deep work or sleep cycle. Ocluv uses a mathematical engine to ensure you never hear the same pattern twice, preventing "audio fatigue" indefinitely.
THE SCIENCE OF SOUND
Based on peer-reviewed research from sources like Nature, PMC, and Frontiers, Ocluv synthesizes specific frequency distributions to target distinct cognitive states:
• Focus & Calm (Volcanic Brown): Mimics deep rumbling to support focus for active minds and promote restorative delta-wave sleep.
• Memory Consolidation (Airy Pink): A balanced harmonic spectrum mathematically optimized to enhance memory retention during deep sleep.
• Deep Focus (Arctic Azure): Uses high-frequency bias to mask speech bands, helping the pre-frontal cortex maintain sustained attention.
• De-stress & Relax (Emerald Green): Mimics nature’s mid-range resonance to promote a general sense of relaxation and calm.
DESIGNED FOR FOCUS, NOT DISTRACTION
Ocluv is built as a precision tool, not an attention trap.
• One-Tap Sleep Protection: Launch Ocluv and it instantly resumes your last session. No need to stare at a bright screen, preserving your melatonin for better sleep.
• Smart Session Timer: Set an 8-hour block for full-night protection or choose 30m/1h/3h for sprints.
• Ultra-Lightweight: Since the sound is generated by code, the app takes up almost zero storage space.
• Minimalist Interface: Zero ads, zero social feeds, and zero gamification.
• Battery Efficient: Optimized for minimal CPU usage during all-night sessions.
100% PRIVATE & OFFLINE
All processing happens directly on your device. No data collection, no internet required, and no account needed. Your peace of mind is absolute.
