Smartphone apps are cheap. You really have to marvel at what has happened to the software world in the past decade. In the bad old days, giant enterprise software vendors roamed the earth, and multi-day training sessions could (and did) make a grown person cry. Expensive licensed software, baffling user interfaces with obscurely named data elements that only the engineers could understand. Although the consolidated 'horsemen of the software apocalypse' still run large enterprises, today, end user expectations have, uh, diminished in scale. Smart phones may cost a few thousand per year in data plans, plus the phone, but software has miniaturized into inexpensive, colorful and graphic versions that by definition, must be intuitive to use, personal and functional – at less than $10/month for a service and only a few dollars for the apps. Why no 'free' apps that are everywhere -- they're not really free. The premium version will have a price: we’re part of a hospital system that wants to help you, we’re funded by advertising. And as with phone pricing, if you're paying for insurance or other care, 'free' is a charming euphemism. Descriptions are from the vendor sites.
