New SNAP software update allow for more consistent & more accurate 3d body scans.
SNAP Software Update: A Step Forward in Accuracy & Reliability
At Fit3D, our mission has always been clear: deliver the very best wellness assessment technology in the world. With this latest SNAP software update, we are once again raising the bar—ensuring every facility, coach, and member can rely on scans that are more accurate, more consistent, and more inspiring than ever before.
What’s New
This update marks another leap forward in the evolution of Fit3D technology:
- Refined accuracy – Circumference predictions have improved from ~±3–4% to ±2.2%, and body fat predictions now align within ±3.5% of DXA, delivering lab-grade precision.
- Greater reliability – Test/retest consistency has tightened from ~±1% to ±0.5%, and overall facility scan success rates have climbed from 91% with ProScanner to 97% with SNAP.
- Expanded capability – New body measurements and improved handling of posture ensure complete results across a wider range of body types and positions.
- Ongoing innovation – A continuation of Fit3D’s commitment to pushing the limits of accuracy, reliability, and business impact with every update.
Why This Matters
Every scan should tell a clear story of progress. Over the past 8 months, SNAP has delivered tens of thousands of scans across the globe. The insights gained from that data—combined with years of ProScanner history—have fueled this update. The result: greater confidence in every result and a smoother experience for both operators and members.
Frequently Asked Questions
What has changed in this model?
Fit3D’s prediction model has always relied on hundreds of data points from body shape, proportions, and scan inputs. This update introduces a new generation of algorithm that delivers measurable improvements across accuracy, consistency, and reliability:
- Historically validated – Our ProScanner was benchmarked against DXA, the gold standard, with body fat predictions tracking within ~5% accuracy. SNAP builds on that foundation with broader datasets and advanced modeling.
- Sharper accuracy – Circumference predictions have improved from ~±3–4% to ±2.2% (a 25–40% boost in precision). Body fat predictions now align within ±3.5% median error compared to DXA, rivaling high-end lab equipment.
- Stronger consistency – Test/retest variation has improved from ~±1% to ±0.5% (a 50% gain in stability), ensuring members see progress that reflects real change—not scan-to-scan noise.
- Scientifically supported – Peer-reviewed research (Frontiers in Medicine, 2024) confirmed smartphone-based 3D imaging delivers lab-grade accuracy with excellent reliability.
- Higher scan success – Facility scan success rates have climbed from 91% with ProScanner to 97% with SNAP, giving operators more complete data with fewer interruptions.
Are my old scans inaccurate?
No. Your previous scans remain valid and useful—they captured accurate body shape and proportions at the time. What has changed is how our algorithm interprets those measurements. With this update, predictions are now more refined:
- Circumference accuracy has improved from ~±3–4% to ±2.2%.
- Consistency has improved from ~±1% to ±0.5%.
- Scan success rates have risen from 91% to 97%.
So while older scans remain reliable, going forward your members will benefit from even more precise, consistent, and complete results.
Will past scans be changed?
No. Past data is preserved as part of each member’s journey. The refinements apply to all scans completed after this update.
Does this affect ProScanner scans?
No. This update is specific to SNAP. ProScanner results remain unchanged, backed by the same accuracy our clients have trusted for years.
Did this impact other metrics?
Yes. Beyond body fat predictions, circumference measurements are now more precise:
- Circumference accuracy improved from ~±3–4% to ±2.2%, a 25–40% improvement.
- Avatars remain unchanged, providing a consistent visual representation.
- BodyShape Score may shift slightly, since it references body composition, but the underlying improvements make it an even stronger indicator of progress.
How does this impact BodyShape Score?
BodyShape Score is designed to reflect overall health risk by combining body composition and body proportions. With this update, those proportions are now measured more accurately:
- Circumference accuracy improved to ±2.2%, making waist, hip, and trunk-to-leg ratios more precise.
- Consistency improved to ±0.5%, ensuring stable tracking over time.
This matters because research has shown that body shape—especially trunk-to-leg ratio—is closely tied to risks like diabetes and mortality, independent of BMI or waist circumference (PLOS ONE, 2013). By refining the underlying data, BodyShape Score now provides an even more accurate reflection of real health risk factors.
Will there be more updates?
Absolutely. Fit3D technology will always evolve. This update is part of our ongoing process to deliver nothing less than the most advanced, trusted, and forward-looking wellness assessment platform in the world.
What about the arm position issue?
In the early days of SNAP, a small number of scans were affected when arms were held too high, leading to incomplete data. This update fully resolves that challenge.
- New body measurements allow the system to better handle a wide range of arm and torso positions.
The result: every scan now delivers a full, dependable set of results—no matter the body type, arm position, or stance.
The Bottom Line
This update represents progress—toward greater accuracy, greater reliability, and greater confidence in every measurement. It’s one more step on Fit3D’s journey to provide the most advanced body scanning platform in the world, built to support the success of your business and the results of your members.
