Hertzy

Tune in to focus, calm, and sleep. Hertzy turns your phone into a precision sound studio — clean tones, binaural beats, and beautiful nature soundscapes — so you can settle in, switch off, and drift away. Beautifully simple, completely yours. DIAL IN ANY FREQUENCY Glide a smooth rotary dial to land on exactly the tone you want, from a deep 90 Hz hum to a bright 852 Hz shimmer. Pick a tone mode and shape the moment: • Pure tones — a single, steady anchor • Binaural beats — a gentle beat for headphone sessions • Isochronic pulses — you can feel them without earbuds SOUNDSCAPES & NOISE Layer in the sound that suits you: • Nature: rain, ocean, jungle, a crackling fireplace, rain on a roof, a calm summer night, a forest stream, and an airplane cabin • Color noise: white, pink, and brown All levelled to an even volume, looping seamlessly for as long as you like. PRESETS, READY TO GO Tap and you're in — Focus, Calm, Sleep, and Meditation, plus the frequencies the internet loves like 432 Hz and 528 Hz. A new Frequency of the Day greets you each morning.
