Needs laptop version and separate iPhone version

I downloaded to my laptop and worked great - a very useful app - but then downloaded a version for my iPhone and my laptop version stopped working. My guess is the iPhone version overwrote the laptop version. Now there is no way to “update” my laptop version. Developer needs to come out with different names for the different platform versions.
