For decades, getting an accurate, medical-grade body composition scan meant visiting a specialized clinic with expensive hardware. Graupel Inc is changing that paradigm with Quadrascan, turning everyday smartphone photography into an instant, fully articulated 3D body model. We put the current beta build through its paces on an iPhone 15 Pro Max to see how well this ambitious utility holds up.
Running beta software on modern Apple Silicon requires apps to optimize for high-frequency neural engine calls and rapid rendering pipelines. Quadrascan utilizes advanced photogrammetry principles to capture accurate anthropometrics without requiring bulky clinical scanners or exposure to radiation. Here is everything you need to know about downloading the beta via Codewing and what to expect from the software.
Quadrascan — Quick Specifications
Developer: Graupel Inc
About Quadrascan
Quadrascan is designed for athletes, fitness professionals, and clinical researchers who need precise longitudinal tracking of human physique. Users complete a guided four-photo capture sequence inside the app, which immediately processes the visual data into a detailed 3D mesh. The core utility revolves around measuring body composition, circumference, breadth, and volume with high repeatability.
Developed by Graupel Inc, the platform targets performance optimization by tracking muscle-to-bone ratios, asymmetry, growth maturation, and peak height velocity modeling. Rather than relying on simple weight scales or consumer bioimpedance devices, Quadrascan provides granular visual data over time. The workflow handles everything from local image processing to encrypted cloud syncing entirely within a clean, minimalist interface.
Standout Features & What's New in this Build
This latest TestFlight build refines the photo capture workflow and speeds up the cloud reconstruction pipeline significantly. The developer has streamlined the user guidance overlay to ensure proper posture and distance during the four-shot capture sequence.
- Instant 3D Modeling: Transforms four rapid smartphone photos into a fully articulated, rotatable 3D body mesh in seconds.
- Advanced Anthropometrics: Calculates precise circumference, breadth, and volume metrics alongside traditional weight tracking.
- Asymmetry Detection: Highlights left-to-right muscular imbalances to help physical therapists and trainers correct training deficiencies.
- Longitudinal Tracking: Stores historical scan data securely to chart long-term body composition changes and growth maturation curves.
- Strict Privacy Compliance: Utilizes GDPR and HIPAA compliant cloud processing pipelines to keep sensitive health data fully encrypted.
Hands-On Impressions: Performance, Battery, and Thermals
Testing an app that renders dense 3D polygon meshes on mobile hardware is always an interesting stress test for thermal throttling. On our A17 Pro-powered test device, the app maintains buttery-smooth frame rates on the ProMotion 120Hz display when rotating and pinching the generated body models. Touch responsiveness is instantaneous, and the local UI animations never stutter even during intensive background network syncs.
Battery consumption is modest during daily tracking sessions, though performing multiple back-to-back 3D reconstructions will gently warm the upper glass back of the phone. Graupel Inc has clearly optimized their ML models to lean heavily on Apple's Neural Engine rather than letting the GPU run wild. The thermal headroom remains well within acceptable limits for a utility of this complexity.

System Requirements & Requested Permissions
To run this TestFlight build of Quadrascan, your device must be running iOS 15.0 or later. While the app functions adequately on standard iPhones, we recommend using a modern device with an A-series chip to ensure swift local image preprocessing before cloud upload.
Upon launching the app for the first time, you will be prompted to grant camera access for the four-photo capture sequence. The app also requests standard local network and background data permissions to synchronize encrypted scans with GDPR and HIPAA compliant cloud servers. Apple's strict sandboxing ensures your visual data remains protected at every step of the pipeline.
Pros & Cons: Beta Impressions
✓ The Highs (What We Love)
- Rapid Capture: Four simple photos generate a complete 3D body model in under a minute.
- Medical Compliance: HIPAA and GDPR cloud standards provide peace of mind for sensitive health metrics.
- UI Fluidity: Silky 120Hz rendering makes manipulating and inspecting the 3D mesh extremely satisfying.
✕ Beta Caveats (Room for Polish)
- Lighting Sensitivity: Dim indoor lighting occasionally triggers capture retries during the photo sequence.
- Queue Times: Peak server hours can occasionally introduce minor delays in 3D mesh rendering completion.
- Device Heat: Extended batch scanning sessions will noticeably warm smaller or older iPhone chassis.
Current TestFlight Slot Situation & Availability
Apple caps public TestFlight betas at a strict limit of 10,000 external users per app ID. Because Graupel Inc has opened this beta globally, slots tend to fill up rapidly whenever tech publications highlight the release. If the official invite link returns a message stating the beta is currently full, do not panic.
Developers routinely prune inactive testers who haven't updated to recent builds, which opens up new batches of seats weekly. We recommend bookmarking this page on Codewing and checking back during off-peak hours to secure your spot when availability refreshes.

Frequently Asked Questions
Is Quadrascan safe to install via TestFlight?
Yes, TestFlight is Apple's official platform for distributing pre-release software. Every build goes through a streamlined Apple review process and runs safely inside iOS cryptographic sandboxes.
What should I do if the Quadrascan beta is full?
If Apple's 10,000-user limit has been reached, check back periodically. Graupel Inc regularly frees up inactive tester slots, making early mornings or late evenings the best times to retry.
Will installing this beta overwrite my App Store version or delete save data?
TestFlight installs beta apps as standalone packages or updates existing development builds securely. Since this app relies on cloud profile storage, your personal tracking data remains safely tied to your account.
How long do TestFlight beta invitations and builds last?
Each individual TestFlight build remains active for 90 days from the upload date. Graupel Inc pushes regular updates through the app to ensure continuous access before public launch.
Are in-app purchases free during TestFlight beta testing?
Yes, any simulated purchases or feature unlocks within TestFlight use Apple's sandbox billing environment. You will not be charged real currency while testing pre-release monetization features.
Final Editorial Verdict
Quadrascan successfully democratizes clinical-grade body composition analysis into a pocket-friendly iOS experience. While minor lighting sensitivities during capture remind us that this is still active beta software, the sheer speed and utility of the 3D modeling engine are immensely impressive. Graupel Inc has crafted an essential tool for fitness professionals, earning a stellar 9.1/10 beta readiness score.
