VoiceDojo
An honest, private vocal MIRROR for teen singers (ages 15–18): cents-level pitch, vibrato, and onset feedback; a range map that grows with your voice (with a gear-shift zone you discover — never gendered); a healthy warm-up ladder; and a RELATIVE vocal-load budget that tells you when to rest (never a decibel). No autotune, no feed, nothing recorded — everything runs on-device.

Meet the cast
VoiceDojo's adapted-DN-S personas (ages 15–18, realistic — NO mascots/illustrated cast, per R-OLDER-TEEN-DN-ADAPTED); each names one honest tool of the vocal mirror. Text-forward; no illustrated chapters/portraits/audio.
Mirror
shows you exactly what your voice is doing — pitch, tuning, and vibrato — and never changes it
Ladder
a gentle, healthy warm-up (straw phonation, lip trills, sirens) — practice, never a cure
Map
your range, growing over time, with the gear-shift zone you discover for yourself (never gendered)
Budget
a relative load meter — tells you when you've been pushing and should rest your voice
