I wanted to like it, iinitially it looked great but it has such a limited window of time view it's no good for planning. A few hours view and that's it. Scrolling hour by hour day by day? Useless. Its sole function appears to be to tell you what you've got coming up in the next few hours which frankly is not much use to anyone as far as I can see. Cloud Cal uses similar circles with a view of the whole month which would be great but sadly the pro version doesn't work so no go there either.
