The idea seems great. However, I encountered a few issues. When downloading from MacUpdate, it "installs" the app via a MacUpdate installer which pushes you try some image editing software junk I didn't even ask for. After declining these options the app did not install. Instead the installer placed a copy of the apps .dmg in my applications folder.
I double clicked it because I really wanted to try the app. The package expanded and it seems there was no installer this time, just the app and a shortcut to add it to the Applications directory.
I moved it to the Applications directory and the app summary indicated it was version 1.3 despite the developers site saying 1.2.1 is the latest version. Anyways, I launched the app and ran update, the app updated and then refused to launch, it crashed every single time I tried to open it. (EXC_CRASH (Code Signature Invalid))
I didn't want to spend more time trying to get this thing to work so I'm uninstalling. In doing so, I found this app set a cookie in my system for tracking. Uggghhhh!
