TechTool review of Cranial Nerve iExam by Sylian on iOS
- What I like about this app is that the developers have made an effort to do something new and different. They could have just listed points. For examples, for CN V motor: clench jaw; raise eyebrows; screw up eyes. Instead they have put in pictures of someone actually doing these tasks. These design elements make the user experience much more enjoyable.
- I would say that the UI doesn’t strike me as a classic Apple user interface (although clearly passed Apple’s approval process) so some of the navigation buttons aren’t intuitive. However it doesn’t take long to get the hang of it.
- Visual field defects. Using great graphics you can put in the visual field deficit and it will give the likely cause (using the optic tract diagram that you can never quite recall when needed).
- Pupil reflex. Integrates with the light on your phone to assess pupils and also helps with diagnosis of abnormal findings.
- Fundoscopy. Shows clear examples of possible fundi findings.
- Sensation. Allows visual representation of CN V sensation testing and interpretation of the deficit.
- Rinne/Weber. Visual display of the test and help working out what the results mean.
- $1.99 – reasonable
Room for Improvement
- It is possible to get stuck in one nerve for a long time. The option to move on to the next nerve does not appear until you have gone through the whole test. The user should have the option of skipping this.
- The Ishihara testing part does not work well. Sliding to move on is unintuitive and I had to spend five minutes working out how to get out of it.
- There is no working website and no way to contact the developers (once I’d downloaded the app I was able to get their contact details from the app itself and they responded very quickly). Setting up a basic website takes five minutes and there’s no excuse for not having proper contact details in the App store.
