Drift

Drift is an ambient soundscape mixer for sleep and focus. Layer nature recordings and synthesised drones, adjust each to taste, and let the sleep timer fade things out.

Design

The interface borrows from cockpit instrument panels with a twin multi-function display for status and the sleep timer. Built for the hours when most things have gone quiet.

Two sound categories sit behind tabs:

• Planetside — field recordings and synths of rain, fire, water, wind, birds, and crickets.
• Deep Space — synthesised drones and a handful of recorded engine/hull textures.

Layers from either category mix freely. Presets bundle useful combinations (Monsoon Run, Hull Storm, Planetfall, Long Haul, and others) for one-tap atmospheres.

Features

• Mix any number of sound layers at independent volumes.
• Two categories: Planetside (nature) and Deep Space (synthesised ambience and recorded hull textures).
• Built-in presets for quick atmospheres.
• Sleep timer with 15, 30, 60, and 90 minute presets.
• Background playback with lock-screen media controls.
• Fully offline. No network access required after install.
• Open source under the MIT licence. Field recordings under Creative Commons, full attribution in CREDITS.md.

The app is a single-page web app wrapped with Capacitor. All audio assets are bundled offline — no CDN, no external dependencies at runtime.

Development tools

The tools/ directory contains a standalone browser-based workbench (sound_lab.html) for designing synth patches. It is not part of the shipping app. See tools/README.md.

Privacy

Drift does not collect, transmit, or store any personal data. It does not connect to the network. There are no ads, no analytics, no crash reporting, and no account system.

The INTERNET permission is not declared in the Android manifest.
