## Description

A Goniometer is a device that measures angles or allows an object to rotate to a specific position. One of its most common uses is measuring a patient's range-of-motion (ROM) for a particular joint. 
This measurement is used to determine the extent of a patient's joint injury and the expected speed of their recovery. 
This goniometer is a basic app that is easy to use.

## Review summary

Users praise the app for accurate, PT-like readings and its usefulness for tracking knee ROM and rehabilitation. However, repeated issues include no or unclear instructions, a confusing Start/End workflow, and outdated iOS compatibility. The tool is limited to sagittal-plane measurements and lacks features like history storage and broader plane support. Clear guidance and feature updates aligned with iOS changes would greatly improve usability and adoption.

### Pros

- Accurate readings comparable to traditional goniometers and PT measurements.
- Helpful for tracking knee range of motion (ROM) and rehab progress over time.
- Simple and easy-to-use interface once the workflow is learned.
- Portability makes it useful for home care and clinicians as a convenient tool.
- Motivational for users undergoing home-based physical therapy.

### Cons

- Lack of clear instructions on how to use the app, leaving many users puzzled.
- Confusing Start/End workflow and calculation method, with unclear how to derive the final value.
- Outdated or inconsistent compatibility with newer iOS versions, requiring updates that are often delayed.
- Limited to measurements in the sagittal plane and vertical orientation; non-vertical/other planes aren’t supported.
- Missing features such as storing multiple readings/history, coronal-plane support, and easier zeroing, despite frequent requests from users.
