Measure audio frequencies and sound tones with ease. Core features work offline, no account required.
Otoyoke is a sound shield for moments when a particular everyday sound feels difficult. Choose among 14 trigger categories and 9 situations, and the app generates a masking blend for that combination on your device.
・Start from the sound that bothers you
Select chewing, slurping, sniffing, keyboard noise, pen clicks, and more. Adjust the level and texture of a blend shaped to cover prominent parts of the chosen trigger.
・Switch by situation
Presets for meals, commuting, office work, studying, and wind-down make it easy to begin. Save favorites and use a timer when you want a defined session.
The app does not listen to, record, or classify nearby audio. Processing stays on device. A banner ad appears on supported screens; an optional one-time ad-removal option hides it.
Important: This is a comfort and focus tool, not a medical device or treatment. Keep listening volume at a safe level and seek professional guidance when sound sensitivity significantly affects daily life.
