Works by can enjoy usability improvements

Basic zoom in and zoom out controls missing in the map view. You can zoom in if you double-click "between quake circles" but there is no way to zoom out. For that, only restart and zoom in again work so far.

Installed and not working

I purchased this and it has not opened without freezing up yet the screen shots look nice but I have not seen it working yet. Developer site is down so there is no tech support available. Avoid unless there is an update that actually works.

Good Idea… Needs More...

I do like the idea of a realtime database of siesmic activity… This is a good start, but I believe that more interactiveness would make this a great app!

Things like area history, making a personal (bookmark) list of areas, frequency data etc. … all very do-able Hint Hint...
