Works fine for me on Yosemite

When I first launched it in Yosemite, it told me that it needed to install Java, that took a few seconds and it now works just fine. It is a very rudimentary app, but does exactly what it promises.Of course, you need the ios app to actually do anything with this, but I do recommend this as an easy and very inexpensive way to geotag with any digital camera.
