## What is SUS4 Vocal Warmup?

Warm up the voice before you sing.

Singing cold is how you strain your voice. SUS4 Vocal Warmup has more than 40 exercises — lip trills, sirens, scale runs, interval jumps — organised into daily routines that take 3 to 6 focused minutes depending on how much time you have. The mic scores each exercise so you know whether you are landing the pitches or just going through the motions.

Routines are built for different contexts: a light warmup before a rehearsal, a full pre-gig routine, a recovery session for a tired voice. Your scoring history shows improvement over time — and tells you honestly when you are not warmed up enough to perform.

• 40+ vocal exercises: lip trills, sirens, scale runs, interval jumps, and more
• Daily routines for different contexts: rehearsal, gig, recovery
• Mic-based scoring — the app listens and tells you how you are doing
• Scoring history so you can track vocal development over time
• Suitable for singers of any level, from amateur to professional
• Subscribe monthly or unlock once for life: full 40+ exercise library, daily routines, and scoring history

All audio stays on your device. No recordings are uploaded.
