Patter is a Mac menu bar ambient sound mixer that layers 17 sounds — rain, coffee shop, waves, thunder, forest, white noise, and more — into a customizable acoustic backdrop for focus or relaxation. ($9.99, one-time)
The sound library spans four categories: six nature sounds (rain, thunder, wind, forest, morning, meadow), two water sounds (waves, shore), six place sounds (coffee shop, fire, busy city, night city, train, bus), and three generated noise types (white, pink, brown). Each sound plays in a seamless loop with no audible break points. Volume levels for each layer are adjusted independently, and the resulting mix can be saved as a named preset. Eight built-in presets cover common scenarios — Rainy Café, Thunderstorm, Seaside, Deep Focus among them — providing a starting point for users who prefer ready-made combinations.
A sleep timer runs up to 90 minutes with a fade-out transition, useful for relaxation sessions or blocking distracting office sounds. The app operates entirely offline; all sounds are stored on-device and the developer’s privacy policy states no network connections are made and no data is collected. Patter also ships as a companion app for iPhone, iPad, Apple Watch, and Android, with Apple Watch playback stored fully on-device.
System requirements: macOS 14 Sonoma or later; universal binary (Apple Silicon and Intel). App size is approximately 37.5 MB.
Pricing: ($9.99, one-time) — single purchase on the Mac App Store; all features and sounds included permanently with no subscription.
Limitations: Sleep timer maximum is 90 minutes, which may not suit users who want all-day background sound. Some audio output configurations do not report volume levels to the app. No trial or free tier is available before purchase.
Alternatives: Noizio ($9.99, one-time) offers a similar layered ambient sound approach with a larger library; Lungo + Noisli (web-based subscription) provides ambient sound alongside browser accessibility; Dark Noise ($9.99, one-time on iOS/macOS) covers overlapping sound categories with an animated icon.
Suitable for users who work in open offices or noisy environments and want offline, one-time-purchase ambient sound control from the Mac menu bar.
