Crescendo 🎶

A voice training app for building pitch accuracy, control, and confidence.

What is Crescendo?

Crescendo is a mobile app that helps singers improve their voice through interactive exercises and real-time pitch feedback. It combines structured vocal warmups with a visual “pitch highway” that shows how closely you’re matching target notes as you sing.

The goal is simple: make vocal practice clear, measurable, and motivating—without needing a piano, teacher, or studio setup.

Core Features

• 🎯 Real-time pitch detection and visual feedback
• 🎼 Range-aware vocal exercises
• 📈 Progress tracking and exercise completion
• 🔓 Difficulty levels that unlock as you improve
• 🔁 Review your last take and replay pitch contours
