Not Yet.

The app falls short. Im sure it works great on the smaller older screens, but doesnt utilize the newer larger screens to transmit information and user friendly fashion.

Newer version seems easier to use and text is easier to read. Phone app is better than tablet version now. More logical and responsive, though tablet text will always be easier to see in any app.
