Yellowcat Labs
Sleep & wellbeing
Brown Noise
Deep brown noise and the sounds of nature — engineered for sleep, focus and calm, with a fade-out sleep timer, gapless looping, offline playback and lock-screen control.
☀ Apps in development
The things we're building.
A first slate of native iOS applications, each focused on a single well-defined area. Brown Noise and Soothy are now on the App Store — the rest are on the way.
2026 release slate
Four apps, each doing one thing well.
We deliberately work on a small number of products at a time so that each one receives the level of attention we believe modern iOS users deserve. Below is what is currently in active development at the studio.
Family & parenting
Soothy
A smart baby sleep tracker — with personalised sleep coaching, nap predictions and curated soothing sounds to help babies (and their parents) rest better.
✓
Focus & goals
A personal habit tracker
A minimal, honest habit tracker with no streak guilt and no gamification — just a clear, daily picture of what matters to you.
✱
Utility
An everyday utility app
A small sharp tool that solves a single recurring problem we kept running into ourselves. Details when it ships.
How we ship
Every Yellowcat Labs application is developed natively in Swift and SwiftUI for iOS and iPadOS. We use Apple's StoreKit framework for in-app purchases and subscriptions, and we publish dedicated privacy policies for every product before launch.
Apps from the studio are released under the Yellowcat Labs developer account on the App Store. If you would like to be notified when a specific product becomes available, please contact us at contact@yellowcatlabs.com.
