Love the design!
Impossible to use You can't actually use the slides, only see them. You can't change the date range, edit them and you can barely scroll in the widgets. You can do everything a lot easier from the phone browser. Make it more interactive, give it some of the options that are hard to use in the phone browser version, then I might use it.
BUG ! Some bugs on formulas.
Added a date picker for date fields.
Fixed occasional problems with validation.
