Logn: Focus, Sleep & Noise

Focus & sleep sounds

Free · In‑App Purchases

Five evolving soundscapes for focus, sleep, and noise masking. Every mode is free. Listen with screen off; remove ads forever with one optional purchase. Logn is a minimal ambient sound app built for deep focus, quiet reading, sleep preparation, thinking, and everyday sound masking. Choose one of five evolving modes and let Logn create a slow-moving soundscape using layered drones, subtle binaural tones, stretched loop textures, soft drift, filtering, reverb, and gentle stereo movement. Each mode has its own character, designed to stay calm and unobtrusive while still feeling alive over time. Modes include: Thinking - spacious tones for calm mental space Working - steady layers for focused sessions Sleeping - slower, softer textures for winding down Reading - light ambience that stays out of the way Masking - fuller background sound for covering distractions The interface is intentionally simple: a glowing control, smooth volume, immersive color, and no clutter. All five modes are free with ads. A one-time Remove Ads purchase removes ads permanently. Audio can continue while your screen is off.
