About this app

Join Kotori-chan for a 5-minute daily, serious vocal training routine.

"I can't hit the right notes at karaoke," "I can't hit high notes," "I can't stick to practicing"—why not solve these problems with the adorable little bird, Kotori-chan?

Kotori Vocal Training is a vocal training app that uses a microphone to determine the pitch of your voice in real time and scores your pitch accuracy on the spot.

■ Practice tailored to your vocal range
- First, measure your vocal range (easy setting using microphone measurement or gender)
- Practice in a key that's perfect for you, avoiding situations where the notes are too low to sing or too high to sing comfortably
- Key and tempo can be adjusted at any time

■ Practice Menu
- Diatonic scale: Basic practice to build a vocal foundation
- 1.5 octave scale: Connecting a wide vocal range in one breath
- Arpeggio: Developing a voice that maintains pitch even when leaping
- Falsetto: Practice producing high notes gently
- Switch between major/minor and change the vocalizations daily (e.g., Na, Ma, I) for a fresh experience every day

■ Real-time evaluation & scoring
- When you sing along to the guide tone, your vocal pitch is displayed as a bar
- Accuracy for each note is displayed immediately, and scoring is automatically performed after the session
- Check your progress with a graph. You can also listen back to recordings of your practice sessions.

■ Features to help you stay motivated
- 5-minute "full practice" sessions make it easy to plan your daily routine
- Reminder notifications remind you of practice times
- Practice records are automatically saved, allowing you to see your progress

■ Recommended for those who:
- Want to improve their pitch accuracy in karaoke scoring
- Have trouble hitting the starting note of songs, or feel they might be tone-deaf
- Want to build a foundation before attending a vocal training class
- Want to practice vocal exercises a little bit each day for free

All features are available for free (with ads).

Start by measuring your vocal range to explore the potential of your voice.
Enjoy fun vocal training with Kotori-chan for just 5 minutes every day! The app uses a microphone to judge and score your pitch in real time. A free vocal training app that helps you improve your singing at your own pace, tailored to your vocal range.
