I used to use it, but the author refuses to publish a desktop app. I actually was able to install the iOS app on my desktop, but if I ever remove it, it is gone forever because he revoked it from the appstore. He only wants you to use the desktop receiver.

It is also buggy af and doesn't sync properly. He's pretty much not doing any more updates of the app either.

That experience pushed me off it forever.

Edit: The app has been acquired by a third party. I'd move off it.
