Warm up first: The meter hears texture, not strain. Pain, scratchiness or hoarseness always mean stop, whatever the meter says.

Before you start
Your voice comes first. HC Vocals is a practice companion. It does not replace lessons or an assessment by a qualified vocal coach, and it's not medical advice. Its tools, like the Scream-o-meter, can make mistakes. Stop immediately if you feel pain, burning, scratchiness or hoarseness, and if it lasts more than 2 weeks, see a doctor (ENT).

A practice mirror for your fry scream. It listens to one scream at a time and shows you three things:
How much fry texture your scream had: No fry, Some fry or Full fry.
Whether it stayed steady, or the texture dropped out along the way.
How long you held it (the ring).
It doesn't judge pitch or volume, so any voice type can use it.
How to use it: warm up first. Tap Scream, do one scream of 1–3 seconds, then stop. The microphone switches off by itself and your result stays on screen. Tap Full fry or No fry to hear Mark's example.
What it can't tell you: whether your technique is right or healthy. A squeezed (compressed), airy or grunty scream can still have plenty of fry texture, so it can still show "Full fry". To check those, compare yourself with Mark's examples and guides, and ask Mark in your lessons.
Where it stands today (Beta)
Mark's own fry screams read Full fry reliably, and screams without fry read No fry.
Squeezed (compressed) screams and shouted, "voicy" screams are its weak spot: they often still show Full fry. If you push, squeeze or shout, don't trust a Full fry.
Other singers' good fry reads Full fry about 6 times in 10. If yours shows Some fry but feels easy and sounds right, it may be the meter, not you.
Your phone and room matter: a quiet room and the phone about an arm's length away work best.
It learned from Mark's own recordings and was tested on more than 80 other voices (male and female), from public coaching videos and the EMVD research recordings (CC BY 4.0).
Please note. This tool is in Beta and can make mistakes; results depend on your phone's microphone and your room. It can't detect false cord or throat techniques: they may show up as fry. It can't hear strain or damage, so "Full fry" never means a scream was safe or healthy. It doesn't replace lessons or an assessment by a qualified vocal coach, and it's not a medical tool. Stop immediately if you feel pain, burning, scratchiness or hoarseness, and see a doctor (ENT) if it lasts more than 2 weeks.
How your warm-up works
Choose your voice, higher or lower. Every scale is recorded in both.
One scale: tap ▶︎ and it plays right away. Several: tap the circles on the right in the order you want, then Play.
Tap Play in the bar at the bottom of the screen. You can change the speed in the player.
The scales are listed from easier to harder. Warming up with the easier ones first is usually kinder to your voice.
Check-in
Be honest — this protects your voice.
