Developers are making customers of previous version of Diagnosaurus repurchase an app they already own just to get upgrades, including iOS 7 support. Dont buy this if you want to make any sort of lasting investment as it will only be a matter of time until youll have to repurchase it again. I spend several hundred dollars a year on medical decision support tools. I was already pretty skeptical of Unbound Medicine but will now go out of my way to avoid their products and encourage my colleagues to as well. Its unbelievable that a supposed professional medical publisher is nickle-and-diming customers over a $2 app.
