ShapeScale's average distance from DEXA
| Criterion | ShapeScale | Styku |
|---|---|---|
| Avg. deviation from DEXA | 0.2 pt | 5.9 pt |
| Visual output | Photorealistic 3D scan (with a high-quality monochrome option); single and before-and-after views; color-coded heatmaps. | Low-quality monochrome 3D scan; single and before-and-after views. |
| Price | $9,990 one-time, or $299/mo on the 12-Month Plan, or $199/mo billed annually; software included | $9,500 hardware one-time plus a $199/mo Access or $499/mo Elite software plan ($349/mo intro) |
“What ShapeScale provides is another level.”
My previous scanner got less specific as patients got healthier. ShapeScale's body-composition analysis is far more accurate, and the images are photographic versus Styku, which looks like a gray blob. I depend on it every day to provide precision medical care.
“Visible, tangible, undeniable proof.”
ShapeScale provides a visible, tangible, absolutely undeniable metric of proof, and it quantifies into a dollar amount from the patient's investment. Styku felt underwhelming, clients said the avatar didn't look like them. ShapeScale actually looks like you.
“Fit3D was too big and imprecise. This isn't.”
Fit3D was too big and imprecise. ShapeScale gives us the precise measurements we need, and clients line up to use it again. We run ads with discounted scans to bring people in, and it opens them to our other services.
“Currently the best thing on the market.”
ShapeScale is currently the best thing on the market because it doesn't just take measurements, it gives images that are relatable rather than a printout of numbers most of us aren't going to look at. It helps with retention, the people interested in this data are in it for the long term.
“A differentiator no one else in our area offers.”
This is a big tool, a differentiator that no one else in our area offers. The ability to quantify outcomes and show patients objective measurement changes, and the ability to close consults, has been better since instituting ShapeScale.
“Manual measurements are full of human error. This isn't.”
Manual measurements are less efficient, less consistent, less accurate, and more intrusive. ShapeScale is easier, more comfortable for clients, and eliminates human error. New clients get a baseline automatically, and existing clients keep seeing progress.

In a same-day, back-to-back comparison against DEXA, ShapeScale was the only device to land close to the reference body fat % for both participants, making it the most accurate against the gold standard.
| Participant | GE Lunar iDXA (reference) | ShapeScale | Styku |
|---|---|---|---|
| Alex ShapeScale co-founder | 10.1% | 10.3% Closest to DEXA for Alex +0.2 pt | 17.8% +7.7 pt |
| Martin ShapeScale co-founder | 16.7% | 16.9% Closest to DEXA for Martin +0.2 pt | 20.7% +4.0 pt |
Alex and Martin, the two participants in this test, are ShapeScale's co-founders.
A note on scope: this comparison covers two people, which is not a statistically significant sample, and we don't present it as a clinical validation. We ran it to compare every scanner directly: same people, back to back, same day, same body conditions.
| Criterion | Recommended ShapeScale | Styku |
|---|---|---|
| 01. Client experience of the scan | Under a minute. The sensors rotate while the client stands still: no balance risk or dizziness. Facial recognition auto check-in. | 30–40 seconds on a turntable (Styku spec sheet). The client rotates, so swaying or losing balance is a risk. |
| 02. Visual output | Photorealistic 3D scan (with a high-quality monochrome option); single and before-and-after views; color-coded heatmaps. | Low-quality monochrome 3D scan; single and before-and-after views. |
| 03. What the device measures |
| Styku · 14 metrics
|
| 04. Data presentation | Free mobile app with intuitive data and visual presentation that clients can understand on their own. | Health Screen results are sold as a paid in-app upgrade (styku.com/pricing). Needs staff interpretation due to too much data. |
| 05. Retention power | Clients rescan to see their photorealistic 3D scan change. | A gray avatar isn't something clients look forward to seeing change. |
| 06. Shareability / marketing power | Photoreal scans plus high-res photo and video exports get shared on social: free marketing. | Few clients post a gray avatar. |
| 07. Trust & perceived authority | Premium hardware, body fat within 1.89 points of DXA on average (March 2026 study, 1,000+ adults), operated with an iOS app. | Two-piece device, dated PC setup, low accuracy. |
| 08. Pricing | $9,990 one-time, or $299/mo on the 12-Month Plan, or $199/mo billed annually; software included | $9,500 hardware one-time plus a $199/mo Access or $499/mo Elite software plan ($349/mo intro) |
