What is the Woo-Woo Meter (and why we built it)

The problem with the wellness tech category

If you walk into a wellness store today — physical or online — you'll find a 10,000-rep PEMF mat sitting next to a quartz singing bowl sitting next to an FDA-cleared blood pressure cuff sitting next to a "scalar energy quantum pendant." All four are sold to the same customer. All four are described in the same confident marketing copy. All four show up in the same Amazon search results.

This is a problem. Not because three of those four don't belong on shelves — they do, and we sell them — but because pretending all four sit in the same evidence bucket is how trust dies.

What the Woo-Woo Meter is

Every product on Wellness Devices gets a single 1–5 rating we call the Woo-Woo Meter. The number tells you exactly where on the science-to-spirit spectrum the product lives:

• 1 — Rigorously science-backed. FDA-cleared and/or replicated RCTs. Examples: blood pressure cuffs, TENS units, SAD lamps.
• 2 — Clinically supported. Real evidence base, narrower or newer. Examples: red light therapy, vagus nerve stimulators.
• 3 — Mixed evidence. Promising signal, marketing tends to outrun the data. Examples: PEMF, hydrogen water.
• 4 — Largely experiential. Devoted users, very little controlled evidence. Examples: grounding mats, EMF shielding.
• 5 — Spiritual practice. Pure experiential or devotional tools. Examples: singing bowls, tuning forks, orgone pyramids.

The number is editorial — it's our judgment, not a vendor claim. We rate the same product the same way whether it pays us a 1% commission or a 20% commission.

Why both ends belong on the site

A few people will read this and ask why we sell anything above a 2 at all. A few more will ask why we'd dilute the spiritual end with science talk. The honest answer is that the buyer at both ends is more sophisticated than either crowd assumes.

The science-leaning customer wants to know when something is unproven so they can opt in or out with eyes open. The practice-leaning customer wants the same thing — they don't want a science-veneer pasted on top of a tradition that's perfectly valid on its own terms.

What both customers hate is pretending. The Woo-Woo Meter is our way of refusing to pretend.

What it's not

It's not a quality rating. A 5 isn't a worse product than a 1 — a hand-tuned crystal singing bowl can be a beautifully made instrument with a real and consistent psychoacoustic effect. That's a different kind of useful than a randomized controlled trial. It's still useful.

It's not a "should you buy this" verdict. We give those separately on each product page.

It's not a permanent label. If a category that's currently a 4 publishes a strong RCT, it moves to a 3. If a category that's currently a 2 has a meta-analysis fail to replicate, it moves to a 3. The meter is alive.

The contract with you

If we recommend a product on this site, three things are true:

1. You can see the Woo-Woo Meter rating before you click the affiliate link. No bait and switch.
2. The rating is the same regardless of commission. We don't bury low-evidence products with high commission, and we don't downgrade high-evidence products with low commission.
3. If we change the rating, we say so. Substantive changes get a "Corrected on [date]" note.

That's the whole methodology. Read the full how-we-test page for the five evaluation pillars we apply on top of the meter.

The wellness tech category is going to keep growing. New devices, new modalities, new claims. Our job is to keep telling you the truth about all of them — including the ones we sell.
