## What is 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.

BUILD A WIND-DOWN HABIT
• Streaks that celebrate showing up — never punishing
• Stats and an active-days view of your listening
• Gentle, optional reminders for bedtime and your daily frequency

MADE FOR SLEEP
• A sleep timer that fades out on its own
• Plays with the screen locked and in the background
• Save the combinations you love — synced through your private iCloud

HERTZY PRO — ONE-TIME, NO SUBSCRIPTION
Unlock everything with a single purchase:
• Every soundscape and the full preset library
• Unlimited saved tones and all-night timers
• Lock Screen & Dynamic Island controls — play, pause, and watch your timer
• No ads, ever

Hertzy is a wellness and relaxation tool. Its tones are not a medical device and are not intended to diagnose, treat, cure, or prevent any condition. The effects of binaural beats are not conclusively proven. Enjoy them as sound, keep the volume comfortable, and consult a professional for medical advice.
