SUS4 Vocal Warmup

SUS4 Vocal Warmup guides you through a structured warmup before you sing. Available on iPhone, iPad, Mac and Apple Watch, the routines move through breathing, humming, lip trills, scales, arpeggios and sirens in a set order, so you prepare the voice properly rather than just running through a few scales.

A warmed-up voice is more reliable and has more range available to it than a cold one. SUS4 Vocal Warmup gives you the routine structure so you do not have to remember what to do or guess at the order: the app plays each reference note, listens through the microphone and scores how accurately you land it, then moves you on to the next exercise. Your scores are kept, so you can see how you are improving.

The Watch integration makes warmup accessible without a screen in front of you. You can hear the cues and feel the haptic prompts while you focus on the physical act of warming up, not on navigating an interface.
