HC Vocals
Warm up. Breathe. Scream better.
The free vocal warm-up app by vocal coach Mark, for singers of all styles: from clean singing to fry screams, growls and distortion.
On iPhone, the app shows you how to add it to your home screen in three taps.
Sound familiar?
Your voice deserves a warm-up
Tired after one song
Going on stage or into rehearsal cold makes the first songs the hardest. A few minutes of warm-up changes that.
Screams that scratch
Pain, scratchiness or hoarseness mean stop. The app helps you check in with your voice every day and tells you when to rest.
No idea what to practice
Mark picks the exercises and sings them with you, from easy to hard, for lower and higher voices.

Questions
Good to know
Is it really free?
Yes. Every exercise is free, with no ads and no account. If the app helps you, you can buy Mark a coffee.
Does it work on iPhone?
Yes. On iPhone you use it in Safari and add it to your home screen; the app shows you how in three taps. On Android you can get it from Google Play.
Does it work without internet?
Yes. Recordings you've played are saved on your phone, and in ⚙ Settings → Practice without internet you can save all of them at once.
I'm a beginner. Is it for me?
Yes. The scales go from easy to hard, and the Gentle warm-up is made for the start, or for tired days.
Is screaming bad for my voice?
Done right, a fry scream shouldn't hurt. If it hurts, scratches or leaves you hoarse, stop and rest. The app's daily voice check-in tells you when it's a rest day. It doesn't replace a teacher, and if problems last, see a doctor (ENT).
What happens to my data?
Your practice stays on your phone. The microphone only turns on when you tap it, in the Pitch and Screaming tabs. Privacy policy
