## Description

Designed by a neuromuscular neurologist at the University of Michigan, Nerve Whiz is a free application for medical professionals interested in learning the complex anatomy of nerve roots, plexuses, and peripheral nerves. Select which muscles are weak, or point to areas of sensory loss, and the application can provide you with distinguishing features and detailed information, complete with relevant pictures and diagrams.

Features
• Nerve and Muscle Charts. This comprehensive inventory of the most clinically relevant muscles in the upper and lower extremities can be sorted by root, trunk, cord, peripheral nerve, action, or muscle name. 
• Muscle Localizer. Select muscles as weak or strong, and the application provides a list of possible localizations (root, plexus, or nerve), along with distinguishing features about each.
• Nerve Diagrams. Choose any localization (root, trunk, cord, or nerve), and see a diagram of that nerve in the context of the brachial or lumbosacral plexus. Toggle to “Muscle View” and the diagram shows you the muscles supplied by your chosen nerve, and from where their innervations arise. 
• Sensory Localizer. Touch a picture of an arm or leg and Nerve Whiz suggests localizations with beautiful graphic representations of the sensory distributions of nerve roots, parts of the plexus, and nerves.

NOTE: Nerve Whiz is intended to be an educational tool only. Nerve distributions vary between patients, and central or multifocal processes can mimic focal peripheral lesions. As such, this application should not be relied upon to make clinical decisions.

This application was funded through the generosity of the Jerry Isler Neuromuscular Fund.

## Review summary

User feedback highlights strong educational value and portability but shows stability and maintenance problems. The app is lauded for its usefulness in teaching neuroanatomy, its free access, and the clear, multi-view presentation that supports diagnosis. However, persistent crashes and freezes, especially on newer iOS versions, plus the long gap since the last update and lack of iPad optimization, hinder regular use. Addressing stability, platform compatibility, and tablet support would unlock the app's significant potential for medical students and clinicians.

### Pros

- Very useful for learning anatomy and clinical localization; praised by students, residents, and clinicians.
- Free to use, with no paywall.
- Well-organized, comprehensive content with multiple viewing options (nerve/roots/muscles, innervation, localization).
- Portable and clinic-friendly; easy to use on the go for reference and quick diagnoses.
- Effective as a study and diagnostic aid in neurology and physiatry.

### Cons

- Frequent crashes/freezes on launch; instability across devices.
- Compatibility issues with newer iOS versions (e.g., iOS 17) and outdated updates.
- Last update years ago; needs active maintenance.
- Not optimized for iPad / lacks universal app support; tablet version requested.
