Sounds for Interoception and Body Awareness before it becomes a crisis.
Some children genuinely do not notice they are hungry, or need the bathroom, or are about to fall apart. The signal is not being ignored, it is not arriving.

What frequency-tuned audio does for noticing what the body is doing
Interoception is the sense that reads internal signals like hunger, temperature, and rising distress, and it is often less reliable for autistic and ADHD people. Practicing with the breath, which is one of the easiest internal signals to notice, builds a habit of checking in, and noticing earlier is what makes every other strategy usable.
What makes this moment hard
- The warning signs are missed until the state is already extreme.
- "How do you feel?" is an impossible question without the signal.
- Adults read missed signals as carelessness rather than a sensory difference.
Resyna does not ask anyone to try. It follows the listener's heart rhythm and uses gentle, adaptive tones to guide breathing toward a slower, steadier pace, with no counting, no instructions, and no screen to look at.
How to use Resyna for noticing what the body is doing
A starting point, not a prescription. Take the steps that fit your family and leave the rest.
- 1 Practice when calm, since noticing is impossible in a crisis.
- 2 Start with one easy signal, like where the breath is felt.
- 3 Use the session as a regular check-in rather than a rescue.
- 4 Pair it with simple language: fast body, slow body, tight, loose.
- 5 Notice out loud together, rather than quizzing your child about it.
Start with two to five minutes at a comfortable volume, and stop any time it does not feel right.
Your body already knows this rhythm. Resyna just holds the door open.
It listens back
Press play and Resyna follows the listener's heart rhythm in real time. As the body settles, the sound settles with it.
It guides the breath
Soft, layered tones pace breathing toward a slower rhythm. Around six breaths a minute is where the body's stress and recovery systems settle back into balance.
It leaves room to breathe
Built with space in it rather than sound filling every second, and it needs no screen. Eyes closed, headphones in, and the calm comes to you.

We would rather earn your trust than your click.
Resyna is not a medical device.
It is a wellness tool designed to support calm and focus. It does not diagnose, treat, cure, or prevent any condition, and it is not a substitute for care from a qualified professional.
We skip the "brainwave" hype.
The research does not reliably support binaural beats retuning your brain, or special "healing frequencies" like 528 Hz. Resyna is built on paced breathing, which does have a strong evidence base, not on claims we cannot stand behind.
Sound is not right for every child.
Many autistic people experience sound sensitivity. That is exactly why Resyna is opt-in, volume-capped, and caregiver-controlled. If sound is not the right tool for your child, that is a completely valid answer.

A gentle note on safe use. Resyna and VizyPlan's Calming Frequency are wellness tools designed to support relaxation. They are not a medical device and are not medical advice. They do not diagnose, treat, cure, or prevent any condition, and they are not a substitute for care from a qualified professional. Start with just 2 to 5 minutes at a comfortable volume and build up gradually. If you feel any discomfort, dizziness, or unease, stop right away. If you are pregnant, or you or your child has epilepsy, a seizure disorder, or a heart condition, please check with your doctor before use. Do not operate heavy machinery after listening. Use of the heart-guided calm score requires a paired Apple Watch with heart-rate and health sharing enabled. The calm score is a relaxation-feedback indicator only. It is not a diagnosis, a fitness metric, or a measure of your health. Resyna does not monitor for, detect, or alert you to arrhythmias, heart conditions, or any other medical issue, and it should never be relied on for that purpose. If you have any health concern, contact a qualified medical professional.
