3DLook’s mobile scanning technology has undergone remarkable advancement in recent years. Our internal validation studies show measurement accuracy within 1.5-2.2 cm for most body measurements—a threshold that meets or exceeds the requirements for most commercial applications.
Key factors driving our accuracy improvements include:
- Larger and more diverse training datasets
- Enhanced pose estimation algorithms
- Continuous feedback loops with enterprise clients
Hardware Scanner Precision
Traditional body scanners still maintain advantages in certain precision metrics:
- Sub-millimeter accuracy for specialized applications
- More consistent results in controlled environments
- Greater point cloud density for surface topology
Research from the Plastic and Reconstructive Surgery journal confirms that professional 3D scanners can achieve mean absolute errors as low as 0.62 ± 0.28 mm in controlled settings.
However, this precision comes with significant trade-offs in terms of accessibility, cost, and deployment flexibility.

Key Comparison Areas
User Experience & Accessibility
The Mobile Advantage: Scanning Anywhere
3DLook’s approach fundamentally transforms the user experience in the health, fitness, and weight management space. Users can scan in their own homes using familiar smartphone technology, completing the entire process in under 30 seconds. Results are available instantly, which significantly enhances client engagement and program adherence. This accessibility has profound implications across multiple health sectors.
The telehealth market has experienced explosive growth, with usage increasing from 15.4% to 86.5% among physicians from 2019 to 2021 and the global market projected to reach USD 1,046.96 billion by 2034.
Weight loss programs have experienced particular benefits from mobile scanning technology. The psychological impact of seeing measurable changes in waist, hip, and other circumference measurements provides powerful motivation during weight plateaus—when scale numbers temporarily stall but body composition continues to improve.
Fitness professionals can now receive consistent measurement data between in-person sessions, helping them adjust programs based on actual results. Wellness coaches support clients in remote locations previously underserved by advanced body composition technology.
The psychological benefits extend beyond convenience—many individuals feel uncomfortable being measured in person, particularly those just beginning their weight loss journey. The privacy of self-scanning removes this barrier to engagement, allowing more people to benefit from body composition monitoring.
Our API architecture enabling seamless incorporation of measurement data into virtual care platforms. This integration allows measurement results to appear alongside other health metrics in patient dashboards, creating a more comprehensive picture of health status for both patients and providers.
The Machine Experience: Controlled but Constrained
Traditional scanners offer a different experience that presents significant barriers, particularly in telehealth and virtual weight management contexts. Users must visit specific locations with controlled lighting and positioning, often requiring appointments that disrupt already busy schedules. Many users report discomfort with booth-style scanning, creating a psychological barrier to regular monitoring.
For telehealth services, the requirement for physical presence fundamentally undermines the remote care model. When working with bariatric patients or those with mobility limitations, traditional scanning becomes practically impossible for regular monitoring. Weight loss programs struggle to maintain consistent measurement protocols across geographic regions where scanning technology availability varies dramatically.
For fitness centers that invest in these machines, the geographic constraints and appointment-based access severely limit their utility for member engagement. The inability to track members between visits represents a missed opportunity for demonstrating value and progress, which directly impacts retention and program success rates.
