## What is PitchPro?

Change the key of any backing track and sing every song in your voice.

PitchPro is an offline-first player built for singers and musicians who need fast, dependable key and tempo control on stage and in rehearsal.

CHANGE KEY WITHOUT CHANGING SPEED
• Transpose any backing track up or down in precise semitone steps.
• Fit the song to your voice while the tempo stays exactly the same.
• Reset to the original key with one tap.

CHANGE SPEED WITHOUT CHANGING KEY
• Slow a track from 0.5x to 1.5x to learn or rehearse.
• The pitch stays locked so the key never drifts.

SAVE EVERY SONG'S KEY IN SETLISTS
• Build show-ready setlists in the exact order you perform.
• Save pitch and tempo for each song, every time it appears.
• Import local MP3, WAV and M4A files.

BUILT FOR THE STAGE
• Large controls, high contrast and a true-dark player.
• Output-route checks before playback.
• Works offline for the core player and library.

FREE AND PREMIUM
The free tier includes unlimited imports, speed control and key changes from -1 to +1 semitone. Premium unlocks the full -12 to +12 semitone range and unlimited setlists. Available plans and prices are always shown by your store.
