Voxscope — Vocal Range

Forty seconds, and your voice has numbers: highest note, lowest note, accuracy, timbre. Then songs and a key that fit your range. Audio never leaves your phone.

Your voice has measurements, too.

Voxscope listens for forty seconds while you follow a simple guide, then puts real numbers on your voice in a single intake chart. Nothing here is invented — every figure comes from the recording itself.

■ The 40-second intake A moment of quiet (to measure the room) → an easy "ahh" → glide slowly up to your highest note → glide slowly down to your lowest → sing a phrase you know. A haptic tap tells you when to move on, so you never have to watch the screen.

■ What you get · Range — from your lowest note to your highest · Pitch accuracy and stability — how close, and how steady · Timbre and vibrato — the texture of the sound and its waver · A comfortable key — where your voice sits easily today

■ It keeps a history Intakes stack up, so a good day and a bad day sit side by side, and so do before and after practice. Save or share any result as a single card.

■ New — carry it to your Mac Export your take as three audio clips (low sweep, high sweep, comfortable phrase). Drop them into the "Vocal Range" intake in Shyun.D on Mac, and that app uses these measurements when it fits a song's key to your voice. Move the files however you like — AirDrop, the Files app, anything.

■ The audio stays on this device Your take is written to a single temporary file and analysed on-device. The app never uploads audio. Exporting happens only when you tap it, and only to where you choose.

Signing in is optional. Everything works without an account; sign in and only your numeric history syncs across devices. You can delete all records at any time in Settings.
