I re-read an article in Fast Company that was written 4 years ago to see if it is still relevant given that there is so much emphasis on mHealth software and applications these days. (Here is that article)
This article lists a few iphone apps that are recommended for Doctors and Providers. Some of these are still around. At that time very few electronic health record systems (EHR systems) were robust enough.
I have seen an evolution of EHR systems that incorporate a lot of functionality that required separate 'apps'.
With majority of them now on the Cloud, you can access not just one or two mHealth apps, but the entire system on your mobile device with a browser.
How times have changed.
