iPhone
Tune out traffic and nearby chatter with brown noise synthesized on your device. Dial in the tone for focused work, winding down, or a quieter night.
Brown FM turns math into deep, continuous brown noise, generated live on-device. Use it as a steady background for sleep, studying, work, or winding down. Adjust the sound to your taste, save your settings, and listen with your screen locked.
HELPFUL FOR
- Falling asleep more easily
- Staying asleep in difficult environments
- Clear focus when working or studying
- Blocking noise when things are bothersome or too loud like traffic, neighbors, barking dogs and more
- Settling down your mind when your thoughts are loud
REAL-TIME SOUND GENERATION
Thousands of calculations each second generate random audio signals. Brown FM softens the higher frequencies and emphasizes the deep rumble, creating the warm, steady sound of brown noise. Adjusting the controls changes how that sound is made in real time. All sound is created on your device and playback works offline.
MAKE IT YOURS
Adjust depth for a deeper or lighter tone, texture for a smoother or more detailed sound, or space for a narrow or wide stereo feel. Enable movement to let depth and texture evolve gently over time. Save your favorite combinations as presets.
SLEEP TIMERS AND GENTLE FADES
Keep the sound playing in the background, through the night or set a specific timer. Customize fade-in and fade-out settings so each session starts and ends gradually.
SIRI, SHORTCUTS, AND WIDGETS
Ask Siri to start playback, choose a saved sound, or set a timer. Build Brown FM into your Shortcuts routines, and keep controls close with Home Screen widgets, Lock Screen widgets, and Control Center. Follow your timer through Live Activities and Dynamic Island on supported devices.
LISTENING INSIGHTS
Explore your listening habits with total listening time, current and best streaks, recent nights, and a seven-night average.
