FAQ
What is 3DSeg/JointAngles used for?
3DSeg/JointAngles measures three-dimensional Cardan/Euler angles of body segments and joints using your iPhone's built-in motion sensors. It's designed for biomechanics researchers, clinicians, physiotherapists, athletic trainers, and students to analyze movement.
Does 3DSeg/JointAngles require external hardware?
No, 3DSeg/JointAngles uses your iPhone's accelerometer, gyroscope, and magnetometer, so no external hardware is required for its motion sensing capabilities.
How accurate are the angle measurements?
The app provides real-time 3D angle display at 60 Hz. For accurate results, it's important to hold the phone still during calibration and keep it away from strong magnetic fields, especially for the Z-axis which uses the magnetometer.
Can I export the data from 3DSeg/JointAngles?
Yes, you can start and stop recording within the app. After recording, the angle data over time can be plotted and exported as a CSV file via email, AirDrop, or any other share destination for further analysis.
Does 3DSeg/JointAngles work offline?
Yes, 3DSeg/JointAngles works completely offline, meaning no internet connection is required to use its measurement and recording features.
Is 3DSeg/JointAngles a medical device?
No, this app is intended for research, education, and rehabilitation purposes. It is not a certified medical device.
What devices is 3DSeg/JointAngles compatible with?
3DSeg/JointAngles is available for iPhone and iPad devices.
How often is 3DSeg/JointAngles updated?
The latest version of 3DSeg/JointAngles is 1.0, and it was last updated on March 28, 2026. This indicates a recent release with potential for future updates.
