Four pillars. One engine.
Pitch Lab, Volume Coach, Voice Analysis, and Breath Trainer share a single measurement core. Underneath each pillar sits a catalogue of specialised drills — from sustained phonation stability to pa-ta-ka diadochokinesis.

Start with a pillar.
Each pillar is fully usable on its own. The app cross-links them so a drill in one feeds the others — your Pitch Lab range, for example, drives the Key Finder and informs the Voice Analysis report.
