Best White Noise Apps in 2026

Disclosure: Slo is developed by the team behind this guide. We include it alongside other apps because we believe in transparency. All app information is sourced from official app store listings.

Finding the right white noise app can be the difference between a restless night and deep, restorative sleep. With dozens of options available across iOS and Android, choosing the right one depends on your specific needs — whether that’s a simple brown noise generator, a feature-rich sound mixer, or an app with guided sleep content.

We’ve tested and compared the best white noise apps available in 2026 to help you find your perfect match.

What to Look For in a White Noise App

Before diving into our recommendations, here’s what matters most:

• Sound quality — Compressed, looping audio is easy to spot and can be distracting. Look for high-quality, seamless playback.
• Sound variety — Different situations call for different sounds. A good app offers noise colors, nature sounds, and ambient textures.
• Mixing capabilities — Layering sounds (rain over brown noise, for example) creates personalized soundscapes.
• Timer functionality — You shouldn’t need sound playing all night. A reliable sleep timer is essential.
• Offline playback — Streaming sounds burns battery and data. Offline support matters for travel and reliability.
• Price — Free apps with ads can be counterproductive for sleep. Understand what you’re paying for.
