“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.
“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.
“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.

Good Design Award Winner 2024 ShapeScale averaged 0.2 points from DEXA in this test; Fit3D was not part of it — Fit3D claims its body-composition estimates land within 3–5% of DEXA (fit3d.com/snap-3d-body-scanner, checked 2026-11-13).
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.
