About
PracticeX shows you which notes were out of tune, so you know what to fix before your next lesson.
Play a scale, or a piece from your own printed music. PracticeX listens and colours every note: blue when you were flat, red when you were sharp, white when you were right on it. A short report card says what went well and what to try next.
Made for violin, viola and cello students, their parents and their teachers.
SCALES AND ARPEGGIOS (no music needed)
• Record with the microphone or choose a recording of a scale or arpeggio
• PracticeX recognises which scale it was and writes it on the staff
• Every note is coloured by how many cents it was off
• Play it again and your takes stack up: you see the note that keeps going wrong, not just a slip
YOUR MUSIC (your own pages)
• Add a PDF, pictures or camera photos of your printed music: etudes, concertos, audition excerpts
• The app reads the notes on your device, and you can correct anything it misread
• Play, and see the colours right on your own page, bar by bar
• Double stops are checked note by note
CHORD TUNER
• Single notes and double or triple stops, live, with the name and the cents
PRIVATE BY DESIGN
• Your playing is analysed on your device: recordings and pictures of your music are not uploaded
• No account, no ads, no tracking
• Players are just names you choose, kept on your device

PracticeX is a practice aid, not a teacher: it hears pitch, and your teacher hears music. Questions or ideas: practicex.app@gmail.com
