Intent

I need it when

Maintain privacy while using ambient sound tools

Blankie is open-source, collects zero personal data, and functions entirely offline. Users can verify the code themselves and trust that their listening habits and preferences are never tracked or transmitted, addressing privacy concerns with commercial alternatives.

Access ambient sounds without subscription or account requirements

Blankie is permanently free with no ads, subscriptions, or mandatory accounts. All 14 sounds and unlimited presets are available immediately upon download, with optional community support via donations, making it accessible to all users regardless of budget.

Block out background noise in noisy environments

Blankie's customizable sound mixing lets users combine multiple ambient sounds at different volumes to mask distracting office, street, or household noise. The offline functionality and native macOS integration ensure reliable, always-available noise masking without internet dependency.

Improve focus and productivity during work or study sessions

Blankie provides 14 high-quality ambient sounds (rain, coffee shop, train, etc.) that users can mix and customize to create a personalized soundscape. Users save favorite combinations as presets for instant one-click access, enabling quick setup for focused work sessions without distractions.

Create a relaxing environment for sleep or meditation

Blankie offers nature sounds (ocean waves, rain, wind, birds) and white/pink noise that can be layered and volume-adjusted individually. Users save relaxation presets and control playback via media keys or AirPods, making it easy to establish a calming routine before sleep.

Drop

Not a fit when

  • User needs ambient sound mixing on Windows or Linux (macOS-only application)
  • User requires custom sound uploads (feature planned but not yet available)
  • User needs iOS or iPadOS support (currently macOS only; iOS/iPadOS in beta via TestFlight)
  • User wants advanced audio editing or production capabilities (Blankie is a simple mixer, not a DAW)
  • User requires cloud sync or cross-device preset synchronization (offline-only, no cloud features)
