Read full description

X-ray Scattering Simulator is a mobile application tool for demonstrating radiation scattering virtually. The demonstrated data is based on real life measurements in a hospital environment. The application is based on Augmented Reality technology (AR) that allows the user to add virtual 3D elements to the real-world environment through the camera of the mobile device. The objects in this application are the patient, X-ray machine and a color map depicting the radiation scattering. The purpose of this application is to demonstrate how the radiation generated during the X-ray imaging scatters to the environment.

Verdict

The call

The clearest difference is price: X at Free against Positioning Pro's $4.99. X also leads on iOS requirement (12.0 vs 15.0). Positioning Pro's advantage is update cadence (weekly vs every 4 months). On ads, in-app purchases and device support there is nothing between them.
