An apple iphone is not the optimal phone for VR, however, any app in VR or AR that works well in it is worth looking in to. Here are some apps I use, almost on a daily basis in regards to learning more about anatomy. They are all free, but lack a lot of interactive abilities. I will do a post on AR apps that have interactive abilities (i.e. can be dragged an moved Hololens style).
4D anatomy - DAQRI
I have previously written about DAQRI, and how they will transform the future. I got found out about DAQRI through this app! I've worked with data where I've had to work closely with bundles of ICD10 diagnosis, and as a non physician, it has helped me navigate the crude anatomy. Print a poser and have fun! There is also a VR function that shows the function of cells!
The Brain AR app
Created by Harmony Studios, this app makes the plastic brain obsolete for neuroscience education and navigation. Although I've always been partial to the analogue brain model, this makes life and education a lot easier. Print a poster, point and look around! It too has a VR function that lets you experience inside the brain!
Wright State Brain Scan
Although it isn't as flashy or sophisticated as the previous apps, brain scan is an excellent app for novices in neurosicence and focuses more on helping people locate the functionality of the different regions rather than learning the anatomy.
