What's My Note is a multimedia application designed for choral singers who may struggle with reading sheet music. It allows users to snap a photo or import JPG, PNG, or PDF files of their sheet music. By simply touching the notes within the image, users can hear the corresponding pitch, making it easier to learn and practice vocal parts. This app is particularly beneficial for those involved in choirs, barbershop quartets, and similar vocal groups, as it aids in recognizing pitches and repeating them for better retention.

The app supports various file formats and features an OCR capability, enabling users to utilize their device's camera for music photography. However, it's important to note that What's My Note does not play scores in their entirety, nor does it interpret rhythms or handle instrumental parts. It is specifically tailored for vocal music, focusing on helping users learn pitches from published choral compositions.
