Push-In Therapy or Pull-Out: What Evidence Says

Resyna and Calm Tools
What These Tools Do Not Do stated plainly.
The wellness sound market is full of confident claims about frequencies rewiring brains. We would rather tell you what the evidence does not support.

Why it works here
Why a calm and focus tool helps with what these tools do not do
The mechanism with the strongest evidence here is unglamorous: breathing more slowly changes measurable physiology. The exciting claims, about specific frequencies and brainwave entrainment, are considerably weaker than the marketing around them suggests.
You will recognize this if
- You have seen claims about specific healing frequencies.
- You want to know what is actually established.
- You are deciding whether this is worth your time.
What the research saysA review of 14 binaural beat studies found 8 contradicting the idea that they reliably retune brainwaves, and the popular 528 Hz claims trace to 1970s numerology rather than to research.
PLOS One review
The setup
How to set it up for the limits of calm and sound tools
Takes about five minutes. Use it as written, or keep only the steps your family needs. A short setup that gets used beats a complete one that gets abandoned in week two.
- 1 Understand the supported mechanism, which is paced breathing and physiological settling
- 2 Treat binaural beat claims with caution, because the evidence is mixed at best
- 3 Disregard specific miracle frequency claims entirely
- 4 Expect support for relaxation, not treatment of any condition
- 5 Watch your own child rather than trusting any average
- 6 Talk to your clinician about anything clinical
The mistake most families make
Any product claiming a specific frequency treats a specific condition is making a claim the evidence does not support. That includes claims made about tools like ours.
In the app
Built into the routine, not bolted onto it.
The Resyna and Calm Tools lives inside the same routine your child already follows, so the limits of calm and sound tools is a step with a visible length rather than a separate tool somebody has to remember to open.
- Attach it to any step in any routine
- Works for pre-readers, gestalt language processors, and AAC users
- Same setup at home, at school, and in therapy
Set this up for your child.
Five minutes to build, and your child sees it every time the limits of calm and sound tools comes around.

Common questions
About the limits of calm and sound tools
Do healing frequencies work?
The specific claims made for particular frequencies are not supported by good evidence. The paced-breathing mechanism is much better supported and much less exciting.
Why include this page at all?
Because we would rather earn your trust than your click, and because a community that gets oversold to constantly deserves at least one honest page.
What is actually established?
That voluntary slow breathing reliably shifts heart rate variability and reduces self-reported stress. That is the mechanism, and it is enough.
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.
