Scalo: Vocal Range Test

Scalo is a game you play with your voice. Sing into your phone and Scalo listens live, scores every note and turns your voice into a journey.

Start by discovering your voice. Six short challenges measure your pitch, rhythm, range, sustain, power and control. Then Scalo reveals your Singer Profile, your singer archetype (a Storyteller? a Power Singer? a Range Explorer?) and the famous singers your profile shares characteristics with.

Then play:
- Six worlds, each built around a singer archetype, with a boss at the end
- Hit the note, follow the melody, hold it, sing on the beat, go soft and loud, stretch your range
- Up to three stars per level, XP, Singer Levels and tokens
- Four coaches who talk you through it: warm, dry, easy-going or theatrical
- A daily challenge, a personal challenge made from your own voice, and a daily reward
- 24 singers to discover as you progress
- Your vocal range from your lowest to your highest note, on a card to share

Every level is set to your own range, so a bass and a soprano both play it where their voice is comfortable.

What you sing stays on your device: Scalo listens only while you sing, records nothing and sends nothing. Free to play. Ads are always optional and always show the reward first; a one time purchase gives you every reward without the ad.

Scalo is a voice game, not a medical test. A phone microphone cannot measure clinical thresholds and Scalo never claims to.

Recent changes:
Your Singer Profile now grows visibly while you sing, on the profile screen too: five tubes standing on the keyboard of your own range, with a mark where you started. The coach no longer talks over herself when you skip ahead, and one tap skips the whole voice analysis. New coach voices in both languages. Clearer recovery when the microphone is blocked, a feedback button in the menu, and a weekly best in practice.
