Simple hobby freeware app calculates and plays the frequency of musical notes based off an adjustable reference pitch, such as A440, A442, A415 etc. Displays the musical note name and octave. Shows a live equation of how it was calculated.
Acts like an electronic tuning fork. Press the button, shake it or bump it to play the pitch. Plays tones continuously. May be used to set up audio equipment or tune instruments. High quality and accuracy sine wave output with 44,000 samples per second.
No ads, no tracking, no permissions, no internet access, no spying, just fun!
Rev 1.4 Reduced the clicking and warble upon first changing notes.
Rev 1.3 - Hooray! After 11 dog years I have finally updated the controls to the app! The new version no longer has the finicky sliders, instead buttons are used to increase and decrease the note and pitch. Some preset common tuning pitches are now included, as well as the ability to save your own favorite.
