How sharp are your ears? Sound Game plays a tone, then challenges you to recreate it from memory using a frequency slider. No notation. No multiple choice. Just you, a sound, and your perception. Each round, a tone between 80 Hz and 1400 Hz plays for 3 seconds. When it stops, slide to match what you heard. Your score is calculated using psychoacoustic distance — the closer you come on the ERB scale (how your ears actually perceive pitch), the higher you score. It's a pure, honest test of your hearing. No tricks, no fake difficulty curves, no pay-to-win. Five tones, one score, shareable. That's it. WHY IT'S DIFFERENT • No multiple choice — guess anywhere on the spectrum • Psychoacoustic scoring, not raw Hertz math • Layered synth with detuned pairs, fifths, octaves, and a sub for real tonal warmth • Haptics + sound design tuned for flow • Minimalist, dark-only interface with animated waveform visuals MODES • 5-round game with cumulative scoring and personal-best tracking • 1-round quick game for fast practice • Easy (80–1200 Hz) and Hard (60–1400 Hz) difficulty WHO IT'S FOR • Musicians doing ear training • Audio engineers checking their frequency recognition • Curious listeners who want to know how good their ears really are • Anyone who enjoys beautifully crafted, focused games PRIVACY • No accounts, no tracking, no analytics • Works 100% offline • No ads, no in-app purchases • Local-only high-score tracking Headphones strongly recommended — the synth's harmonic layers get lost on phone speakers.
