Not all anxiety devices work the same way.
Some simply help you relax in the moment by encouraging slower breathing or mindfulness. Others monitor your heart rate or stress levels without actively treating anxiety. A much smaller group are regulated medical devices that have been evaluated in clinical trials.
Before spending money on any anxiety relief device, it's worth considering the following questions.
1. Is There Clinical Evidence?
The strongest evidence comes from randomised controlled trials (RCTs) that compare an active device with an identical sham (placebo) device.
Reliable anxiety studies typically measure outcomes using recognised assessment tools such as:
- Generalised Anxiety Disorder Scale (GAD-7)
- Hamilton Anxiety Rating Scale (HAM-A)
- State-Trait Anxiety Inventory (STAI)
Many consumer wellness products rely on general research about breathing exercises or meditation rather than studies performed on the specific product being sold.
Medical devices such as Alpha-Stim, however, have been evaluated in multiple independent clinical trials over several decades.

2. Is It Practical to Use Every Day?
Even an effective device needs to fit into your lifestyle.
Ask yourself:
- How long is each treatment session?
- Can you use it while reading or watching TV?
- Does it require a subscription?
- Is it portable?
- Will you realistically use it consistently?
Many anxiety devices require ongoing daily use before noticeable improvements occur, making convenience an important consideration.
3. Is It a Wellness Gadget or a Medical Device?
This distinction is often overlooked.
Many products marketed for anxiety are simply consumer electronics designed to encourage relaxation.
Medical devices are different.
They must meet regulatory requirements regarding safety and intended use, and manufacturers must be able to support their claims with appropriate evidence.
For people seeking a drug-free treatment option rather than a simple relaxation aid, this distinction matters.
4. What Does It Cost?
Prices vary considerably across New Zealand.
Typical price ranges include:
| Device Category | Approximate NZ Price |
|---|---|
| Breathing devices | $100–$650 |
| Stress-tracking wearables | $75–$1,400 |
| Biofeedback devices | $100–$700 |
| CES medical devices | $840+ |
Some providers also offer rental programmes, allowing you to try a device before committing to a full purchase.
For example, Alpha-Stim NZ offers a rent-before-you-buy option, making it easier to experience CES therapy before deciding whether to purchase a device.
Anxiety Relief Devices Available in New Zealand
The New Zealand market now includes dozens of products claiming to reduce anxiety.
They generally fall into four main categories:
- Wearable stress trackers
- Breathing and HRV biofeedback devices
- Consumer relaxation gadgets
- Cranial Electrotherapy Stimulation (CES) devices
Each category has different levels of scientific evidence and different expectations for results. In the following sections, we'll compare these options to help you understand which devices are backed by clinical research and which are primarily designed for general wellness.
Wearable Anxiety Devices: Helpful or Just Hype?
Wearable anxiety devices have become increasingly popular in New Zealand. Many promise to help users feel calmer, sleep better, or reduce stress using vibration, breathing guidance, or physiological monitoring.
While some people report positive experiences, it's important to understand that not all wearable devices are supported by the same level of clinical evidence.
Many are designed as wellness tools rather than medical treatments, meaning they may support relaxation without directly treating anxiety disorders. Let's look at the most common categories.
HRV Biofeedback and Breathing Devices
Devices such as Apollo Neuro, Moonbird, and other breathing-guided wearables aim to help regulate the nervous system by encouraging slow, controlled breathing or gentle vibration patterns.
The concept behind these products isn't new.
Research has shown that heart rate variability (HRV) biofeedback and controlled breathing may help some people manage stress and improve relaxation.
However, an important distinction needs to be made.
Much of the available research supports HRV biofeedback as a therapeutic technique, not necessarily the specific commercial device being sold.
Many branded products have limited device-specific clinical trials, making it difficult to determine whether the individual product performs as advertised.
Pros
- Drug-free
- Easy to use
- Portable
- Can encourage healthy breathing habits
- May improve relaxation for some users
Limitations
- Limited device-specific clinical research
- Most are not regulated medical devices
- Results vary considerably between users
- Often require an app or subscription
For people experiencing occasional stress, these devices may provide useful support.
For individuals living with Generalised Anxiety Disorder (GAD) or persistent anxiety, the available evidence is considerably less robust than that supporting clinically studied medical devices.
Smartwatches and Stress Tracking Wearables
Fitness watches from brands such as:
- Apple Watch
- Garmin
- Fitbit
- Samsung
have introduced stress scores, heart rate variability tracking and breathing reminders.
These features can certainly increase awareness of stress patterns.
However, it's important to understand what these devices actually do.
They monitor stress.
They do not treat anxiety.
Knowing your stress score can encourage healthier habits, but monitoring alone should not be confused with therapy.
For someone managing chronic anxiety, panic attacks or insomnia, passive tracking is unlikely to provide meaningful symptom relief on its own.
Best suited for
- Fitness enthusiasts
- General wellbeing
- Lifestyle tracking
- Sleep monitoring
Less suitable for
- Clinically significant anxiety
- Persistent insomnia
- Long-term anxiety management
Consumer Biofeedback Devices
Products such as Calmstone and similar biofeedback devices are marketed as non-drug tools for reducing stress and anxiety.
Their popularity continues to grow because many people are looking for alternatives to medication.
While biofeedback techniques themselves have been studied for many years, the evidence supporting individual consumer products remains mixed.
Most devices currently available in New Zealand have not been evaluated in large sham-controlled randomised clinical trials specifically for anxiety.
Some users report noticeable improvements.
Others experience little or no benefit.
Because outcomes vary widely, these products are generally best viewed as relaxation tools rather than clinically validated anxiety treatments.
Consumer Wellness Devices vs Medical Devices
This is where many buyers become confused.
A product marketed for relaxation is not necessarily a medical device.
Most wellness products are designed to promote calmness, mindfulness or better breathing.
Medical devices, on the other hand, are developed for specific therapeutic purposes and are supported by clinical evidence demonstrating safety and effectiveness.
This distinction becomes particularly important when choosing a device to help manage:
- Generalised Anxiety Disorder
- Panic attacks
- Chronic stress
- Anxiety-related insomnia
If you're looking for an evidence-based, drug-free therapy rather than a wellness gadget, it's worth considering whether the device has been independently studied in clinical trials.
Cranial Electrotherapy Stimulation (CES): A Different Category
Unlike breathing gadgets, vibrating wearables and stress trackers, cranial electrotherapy stimulation (CES) is a recognised medical technology that has been researched for decades.
Rather than simply monitoring stress or guiding breathing, CES delivers a very low-level electrical microcurrent through soft ear clip electrodes.
The treatment is typically used for around 20 minutes per day while you relax, read, or watch television.
This microcurrent is designed to gently interact with the brain's natural electrical activity and has been studied extensively for anxiety, insomnia and related conditions.
Among CES devices available in New Zealand, Alpha-Stim® has the largest body of published clinical research and is distributed exclusively through Alpha-Stim NZ.

Why CES Deserves Its Own Category
Unlike most consumer wellness products, CES devices such as Alpha-Stim have been evaluated using:
- Randomised controlled trials
- Sham-controlled studies
- Published systematic reviews
- Meta-analyses
- More than 40 years of clinical research
This level of evidence places CES in a different category from general wellness gadgets and consumer relaxation devices. In the next section, we'll look specifically at Alpha-Stim, the clinical evidence supporting it, and why many healthcare professionals consider it one of the most researched drug-free anxiety treatment devices available today.
Alpha-Stim®: The Most Clinically Researched Anxiety Relief Device Available in New Zealand
When comparing anxiety relief devices, one product consistently stands apart because of the depth of clinical evidence supporting it.
Alpha-Stim® is a cranial electrotherapy stimulation (CES) medical device that has been used by healthcare professionals worldwide for more than 40 years. Unlike many consumer wellness products, its intended use is supported by published clinical research, including randomised controlled trials, systematic reviews, and meta-analyses.
Available exclusively through Alpha-Stim NZ, it is currently the only FDA-cleared CES device available in New Zealand.
If you're looking for a drug-free option for anxiety, stress-related insomnia, or persistent nervous system dysregulation, Alpha-Stim offers one of the strongest evidence bases currently available. Learn more about the science behind CES on our Clinical Research page.
How Alpha-Stim Works
Alpha-Stim uses cranial electrotherapy stimulation (CES), which delivers an extremely low-level electrical microcurrent through soft ear clip electrodes.
Treatment sessions usually take around 20 minutes, during which many people simply relax, read, or watch television.
Unlike devices that monitor stress levels or guide breathing exercises, CES works by delivering a carefully controlled microcurrent that has been studied for its effects on brain activity associated with anxiety and sleep regulation.
Because the current is extremely low, most users feel either a mild tingling sensation or nothing at all during treatment.

What Does the Research Say?
One of Alpha-Stim's greatest strengths is the amount of independent clinical research supporting its use.
Over four decades, researchers have evaluated Alpha-Stim in multiple studies investigating anxiety, insomnia and depression.
Among the published evidence are:
- Randomised controlled trials (RCTs)
- Sham-controlled clinical studies
- Systematic reviews
- Meta-analyses
- Independent research conducted in multiple countries
Unlike many wellness devices, Alpha-Stim has repeatedly been evaluated using recognised anxiety assessment tools such as:
- Hamilton Anxiety Rating Scale (HAM-A)
- Generalised Anxiety Disorder scales
- State-Trait Anxiety Inventory (STAI)
Independent Reviews of Alpha-Stim
Several respected organisations have reviewed the evidence supporting Alpha-Stim.
NICE Review
The UK's National Institute for Health and Care Excellence (NICE) reviewed multiple clinical studies involving Alpha-Stim.
Its assessment found improvements in patient-reported anxiety symptoms when compared with sham treatment and other treatment approaches.
Systematic Reviews
Independent systematic reviews examining cranial electrotherapy stimulation have reported modest to moderate improvements in anxiety symptoms across multiple clinical trials.
Meta-analyses focusing specifically on Alpha-Stim have also demonstrated meaningful improvements in anxiety scores among study participants.
Together, these findings contribute to one of the strongest evidence bases currently available for a non-drug anxiety device. Explore the published research on our Clinical Evidence page.

Why Generic CES Devices Are Not the Same
You may come across inexpensive ear-clip CES devices sold through online marketplaces.
Although they may appear similar, appearance alone does not indicate equivalent performance.
The published clinical studies referenced throughout this article were conducted using Alpha-Stim devices and Alpha-Stim's proprietary waveform.
That evidence cannot automatically be applied to unbranded CES devices.
A generic device may resemble Alpha-Stim, but it has not necessarily undergone the same clinical evaluation or demonstrated comparable outcomes.
When comparing products, it's important to consider not only the technology but also the quality and quantity of research supporting the specific device.
Why Many New Zealanders Choose Alpha-Stim
People choose Alpha-Stim for a variety of reasons, including:
- More than 40 years of published clinical research
- Drug-free therapy
- FDA-cleared medical device
- Available throughout New Zealand
- Supported by experienced local clinicians
- Rent-before-you-buy option
- Ongoing customer support
Pricing and Availability in New Zealand
