## Description

Hunt a target frequency with any sound — voice, whistle, hum, tap, scrape, instrument, or playback. Pick 100/200/1000 Hz or custom up to 10000 Hz. Test your pitch sense.

Tone-Sense is a minimalist pitch-matching mini-game. Hunt a target frequency by producing any sound the microphone can pick up — your voice, a whistle, a hum, tapping or scraping an object, an instrument, or even audio played from another device. The app uses the microphone purely for on-device pitch analysis — nothing is recorded, saved, or sent anywhere.

■ How to play
1. Pick a target pitch (100 / 200 / 1000 Hz, or a custom value in 100 Hz steps up to 10000 Hz)
2. Hold the mic button and produce a sound close to the target (up to 3 seconds)
3. Release the button — the dominant frequency of your sound is estimated and compared to the target

■ Judgment tiers
- INSANE — within ±3% (near-perfect pitch)
- Great — within ±10%
- Otherwise

■ Features
- Voice, whistle, humming, tapping or scraping objects, instruments, or any external tone source — anything that produces a clear pitch works
- On-device pitch detection using AVAudioEngine + FFT (Accelerate framework). No server, no disk save, no leakage
- Two visual themes: Cyber (neon green) and Soft (warm cream)
- Bilingual UI (Japanese / English)
- In-app help sheet explaining what "frequency / Hz" means
- Works fully offline

■ Privacy
Data collected: none. Microphone audio is processed only in memory during a measurement, then immediately discarded. No advertising, no analytics, no third-party SDKs.

"Tone-Sense" is the third entry in the Sense series (Tilt Hit / Hertz Sense / Tone-Sense).
