Vibrato Game
Read full descriptionHide full description
Train your ear. Shape your sound. Master vibrato. Vibrato Game turns serious musicianship training into a fun, focused challenge. Learn to hear and shape the two parameters that define great vibrato: speed (Hz) and amplitude (cents). Build the same core skills top artists rely on, one challenge at a time. Whether you’re a violinist, flutist, singer, or another musician who uses vibrato, Vibrato Game helps you improve speed and amplitude awareness, consistency, and expressive control through fast, game-style practice sessions. What you can do: • Train Speed, Amplitude, and Mixed vibrato perception • Survive Drop, the arcade mode where falling tone cards test your reflexes and your ear under pressure • Use Match and Virtuoso modes to listen more deeply and shape vibrato by ear • Practice endlessly in Blitz and freely explore vibrato parameter combinations in Lab • Track progress with scores, streaks, and achievements • Challenge a friend in local multiplayer duels Plenty to play for free: Speed, Amplitude, Speed and Amplitude Drop challenges, local duels, and more are completely free. There are no ads or accounts, and core gameplay works offline. Every Pro mode includes a free preview of the real gameplay, so you always know what you’re getting before paying. Unlock everything forever with a single one-time purchase. No subscription. Pro opens Mixed, Match, Virtuoso, all Blitz modes, Mixed Drop, and the complete Lab range. Start with quick, fun practice. Build real vibrato mastery.

Verdict
The clearest difference is update cadence: IMSLP at every 10 days against Vibrato Game's every 6 months. IMSLP also leads on iOS requirement (13.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
