Feliks is a clean and intuitive music tool built for musicians, educators, and anyone who works with pitch. Whether you are tuning your instrument, checking a vocal line, or quickly exploring harmonies, Feliks gives you the essentials in a beautifully simple interface.
Two modes for everyday music work
• Listening Mode – a precise chromatic tuner that displays pitch deviation in cents and highlights the detected note directly on the keyboard. Ideal for tuning, ear training, choir work, or identifying the pitch someone starts singing on.
• Playing Mode – a responsive one-octave piano for quick reference, practicing intervals, starting tones, or testing harmonies during rehearsals.
Made for iPhone, iPad, and Apple Watch
Feliks works seamlessly across your devices.
On Apple Watch, enjoy a simplified, fast tuner optimized for quick checks when you don’t have your instrument or phone at hand.
