Description

Otoful is an ear-training and singing-practice app that gives you instant feedback the moment you sing. For anyone who wants to harmonize in a cappella, choir, or karaoke, stop being "tone deaf," or build a foundation for vocal training. Not listen-only or tap-only—you improve by checking your own pitch with your own voice.

■ Ear training that talks back
This isn't listen-only or tap-only practice. You sing, and you see in real time whether you're on pitch or off—and by how much. So you don't just feel like you understand; you actually train an ear and a voice that can sing in tune.

■ Who it's for
・Singers in a cappella or choir groups who want to harmonize with the people around them
・Anyone unsure about their pitch who wants to stop being "tone deaf"
・People building a foundation for karaoke or vocal lessons
・Anyone who'd rather practice the basics at their own pace, without relying on a more experienced member

■ Features
・Real-time pitch detection: instant feedback every time you sing—right or off, and how far.
・Daily lessons: a few minutes each. Short and easy to keep up with.
・Rewards for showing up: track your streak and total practice. We celebrate the habit first, before progress.
・Beginner-friendly tolerance: no harsh scoring out of the gate—land notes that feel good while you sharpen your accuracy over time.

■ Designed to keep you going
Judging too strictly breaks beginners. Otoful aims for the sweet spot: satisfying to get right, yet you still feel yourself improving. No demoralizing leaderboards—the only person you're compared to is yesterday's you.

■ Good to know
・Uses your microphone. Headphones are recommended during practice (they help separate the reference tone from your own voice).
・No account needed. Your practice data stays on your device.
・Free, supported by ads.

All you need is your voice—no instrument required—to start building your musical foundation today. Aim for the day you can harmonize a song on your own.
