Can you identify a musical note just by hearing it? Absolute pitch may seem like a rare gift, but anyone can sharpen their ear with practice. Onkan is a quiz-style training app where you listen to a tone and choose the correct note name from four options. Through repeated play, you can steadily improve your ability to recognize pitches. Features: - Three difficulty levels (Easy / Normal / Hard) - 10-question quiz measuring accuracy and response speed - Faster, more accurate answers earn higher scores (max 120 points) - Five-tier ranking system (AbsolutePitch to Novice) - Track your score history over time - Share results and compete with friends - Japanese / English language support Easy uses only the seven white keys. Normal adds sharps and flats for all 12 notes. Hard spans two full octaves with 24 possible notes. Progress at your own pace. Whether you are studying music theory, picking up an instrument, or just looking for a fun challenge with friends, a few minutes each day can transform the way you hear music.
