APECS
AI Posture Evaluation
& Correction System
The most cited photogrammetry-based posture analysis platform available on mobile. Built by clinicians. Validated by independent researchers on six continents.
What is APECS
Industry-grade precision.
Unmatched accessibility.
APECS — AI Posture Evaluation and Correction System — is a digital photogrammetry platform that turns a standard smartphone or tablet into a precise postural measurement instrument.
Referenced in peer-reviewed journals, master's theses, and clinical studies year after year, APECS has earned its place as a trusted scientific instrument — not just an app. Precise. Reproducible. Academically credible.
Clinical-grade posture analysis should not require laboratory budgets. APECS makes objective biomechanical measurement accessible to individual practitioners, universities, and institutions worldwide — at a fraction of the cost of motion-capture or lab systems.
ISO-aligned photogrammetric method
Validated against radiographic measures
PDF report generation
No calibration equipment required
Used in research worldwide
Measurement Modules
Every angle.
Every plane.
One instrument.
APECS covers the full spectrum of postural evaluation — from quick screening to comprehensive multi-segment analysis — without requiring any external equipment beyond the device already in your pocket.
Full Posture Analysis
A complete multi-segment postural evaluation covering frontal, lateral, and posterior planes simultaneously. APECS analyses multiple body landmarks, calculates angular deviations against established biomechanical norms, and outputs a structured PDF report ready to share, archive, or print.
- Body alignment, head tilt, shoulder symmetry
- Ribcage inclination, pelvic tilt, ASIS measurement
- Knee angles and foot rotation — left and right independently
- Automatic deviation flagging against clinical norms
- Printable PDF report with patient data and timestamps
Head-Neck & Range of Motion
Targeted assessment modules for cervical and cranial positioning, plus dynamic range of motion evaluation with frame-by-frame video analysis. Clinically relevant angles calculated and displayed in real time with reference lines.
- Craniovertebral angle and forward head posture index
- Cervical lateral flexion and rotation
- Video-based ROM measurement — no wearables needed
- Temporal graphs for repeated-measure tracking
Trunk Symmetry & Golden Ratio
Precise frontal-plane trunk analysis and a unique implementation of the golden ratio as a proportional reference tool. Used in sports medicine and aesthetic assessments where bilateral symmetry and body proportion are clinically meaningful.
- Bilateral shoulder, waist, and hip symmetry indices
- Trunk inclination and lateral deviation measurement
- Golden ratio proportional overlays with automatic calculation
- Used in validated research on postural aesthetics and athletic screening
Who Uses APECS
Trusted by professionals who need results they can defend.
APECS is used daily by physiotherapists, sports medicine physicians, osteopaths, chiropractors, ergonomists, and researchers. It is the only mobile photogrammetry system with this depth of independent peer-reviewed validation.
For over 10 years APECS has been continuously refined by a focused, mission-driven team. It is not a short-term product — it is a decade-long commitment to better health measurement.
