SING TRAINER

Features

Everything your voice needs.

Built for singers, instrumentalists, and anyone who wants a more reliable voice.

🎤
Real-time pitch feedback
Sing into the mic and see your pitch plotted against the target in real time. Every cent of deviation visible instantly — no more guessing whether you're sharp or flat.
🎼
Sustained tone practice
Match and hold a steady pitch. The app tracks how long you stay locked in tune and scores your hold. The foundation every singer needs.
🎯
Interval drills
Sing specific intervals from any root. All 12 keys, ascending and descending. Train the intervals you actually use instead of grinding random exercises.
🎙️
Voice range calibration
Sing your lowest and highest comfortable note. The app sets your range automatically so drills stay inside your voice — not outside it.
📈
Progress tracking
Every session saved. Watch your in-tune percentage, hold times, and range expand week over week. Data that actually tells you if you're improving.
🔒
On-device processing
Your microphone audio never leaves your phone. Pitch detection runs locally. No servers, no uploads, no recording — just the app and your voice.
