## Description

HundredHz is a lightweight tool to help ease motion sickness, inspired by public research on low-frequency sound and inner-ear balance. When you feel uneasy in a car, boat, or plane, put on your headphones, pick a sound, and listen for about a minute to relax and ease travel discomfort.

SOUND LIBRARY
All synthesized on-device, clean and precise:
• 100Hz otolith tone (recommended, a research-based low tone)
• 50Hz / 150Hz low tones
• White noise, pink noise (relax, sleep)
• 100Hz + white noise (layered)

GUIDED BREATHING
An optional breathing guide: inhale 4s, hold 2s, exhale 6s, with a ring that scales to your breath. Slow, deep breathing can itself help with nausea.

ADJUSTABLE DURATION
1 / 3 / 5 minutes. Stops automatically, or stop anytime.

SESSION HISTORY
Every listen is logged — see your day streak, total sessions, and minutes.

MOTION-SICKNESS TIPS
Built-in guidance: why motion sickness happens, practical tips to feel better, and notes on the 100Hz research.

THOUGHTFUL DETAILS
• Headphones recommended for better low-frequency reproduction
• A flowing waveform while playing, with a clear Stop button
• Plays through headphones even with the silent switch on
• Stops automatically on a call or when headphones are unplugged
• English and Chinese, following your system language

PLEASE NOTE
HundredHz is a relaxation and comfort aid based on public research. It is not a medical device and is not a substitute for medical diagnosis or treatment. If discomfort persists or is severe, please consult a doctor; stop immediately if you feel unwell while listening.
