Calm that does not ask for energy you already spent.
Almost every calming strategy bills the person who is already overdrawn. Count your breaths. Name the feeling. Sit still. Those are real skills worth building, and none of them are available to a child at 4:45 who has run out of words, or to a parent at 10pm who has run out of everything.
Resyna is our patent-pending frequency-based calm and focus support, built into VizyPlan alongside the breathing and calming sound tools. It works by guiding breathing toward a steadier pace with gentle adaptive tones, which means it does the work rather than asking the listener to. Eyes closed, nothing to look at, nothing to get right.
These pages cover the specific moments families use it for, and they include the honest limits. Sound is genuinely not right for every child, and saying so matters more to us than a click.

A meta-analysis pooling 223 studies found that voluntary slow breathing reliably increases vagally-mediated heart rate variability, with few adverse effects expected.
Neuroscience and Biobehavioral Reviews, 2022A meta-analysis in Psychological Medicine found that training slow breathing produced a large reduction in self-reported stress and anxiety.
Psychological Medicine, 2017Breathing entrains to musical rhythm, and in one study random pauses inserted into music dropped heart rate and blood pressure below the resting baseline, meaning the silence between sounds did more than silence alone.
Bernardi et al., HeartThe honest limit: binaural beats do not reliably retune brainwaves. A review of 14 studies found 8 contradicting the idea, and the popular 528 Hz claims trace to 1970s numerology rather than to evidence.
PLOS One reviewSound is not right for every child. A meta-analysis of 13,433 autistic individuals found roughly 41 percent currently experience decreased sound tolerance, which is why every tool here is opt-in and starts quiet.
Meta-analysis of decreased sound tolerance in autismResyna 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.
Every moment families use it for.
Each one is its own guide, with the setup, the mistake most families make, and the questions parents actually ask.
Winding Down at Bedtime
The routine is finished, the lights are off, and your child is still going. Their body has not caught up with the fact that the day is over.
When the Mind Will Not Stop at Night
Your child is exhausted and cannot stop thinking. They are narrating the day, replaying something that happened at school, or working through a subject they love, and none of it will switch off.
After a Meltdown
The worst of it has passed. You are both on the hallway floor, wrung out, and every sentence you can think of to say would be the wrong one.
In the Car After School
Your child holds it together for six and a half hours and then gets in the car, and the first ten minutes decide how the whole evening goes.
In a Waiting Room
Twenty-five minutes past your appointment time, under fluorescent lights, with a television nobody chose. The appointment is not the problem. The room is.
Focus During Homework
Your child cannot work with the television on downstairs, a sibling in the next room, and a dishwasher running. Your house is not a library and it never will be.
For a Parent at the End of the Day
It is 10pm, the house is quiet for the first time since six in the morning, and you are too tired to sleep and too wired to rest. Tomorrow starts in eight hours.
For a Provider Between Sessions
You have eleven minutes between clients, three notes to write, and you have given everything to other people's children since seven this morning.
For a Sound Sensitive Child
Your child covers their ears at the vacuum, the hand dryer, and the school bell. Offering them an audio tool seems either exactly right or completely wrong, and you cannot tell which.
What These Tools Do Not Do
The wellness sound market is full of confident claims about frequencies rewiring brains. We would rather tell you what the evidence does not support.
Building It Into a Routine
You downloaded it during a hard week, used it twice, and have not opened it since. It is now something you remember about only when things are already bad.
Before a Difficult Transition
You know exactly which transition is going to be hard. It is the same one every day, and you have never done anything before it except brace.
Sleeping Away From Home
A different bed, different smells, unfamiliar noises, and a room with the light in the wrong place. Your child settles fine at home and not anywhere else.
When the House Is Too Loud
Three children, a television, a dog, and a kitchen. Your sensory-sensitive child is drowning in a household that is behaving completely normally.
Introducing It to a Child Who Refuses New Things
Your child refuses anything new on principle, which means the tool that might genuinely help is the tool they will not try.
How Long a Session Should Be
You assumed longer would be better, ran a twenty-minute session on the first attempt, and your child will not go near it again.
Using It Alongside Therapy
Your child sees an OT for regulation work and you have started using a calm tool at home. Nobody has connected the two, and you are not sure whether you should mention it.
The Sunday Night Reset
Sunday evening in your house is dread. Your child feels it, you feel it, and Monday morning is being decided right now by how tonight goes.
When a Child Cannot Name What Is Wrong
Something is wrong and your child cannot tell you what. Every question you ask makes it worse, because answering questions is exactly what they cannot do right now.
Before a Performance or Test
Your child has revised, they know the material, and in the ten minutes before the exam their body is behaving as though something dangerous is about to happen.
Choosing Headphones or a Speaker
You bought headphones, your child hates the feeling of them, and you have concluded that the audio tool does not work. The audio was never the problem.
The First Hour of a Hard Morning
Something went wrong at 6:50 and the morning is now a write-off with fifty minutes still to run before school.
For a Grandparent or Carer
Your parents look after your child one day a week and have no idea what to do when things escalate. You have explained it twice and it did not transfer.
