TodayCalc(Notification Center Calc) app for iPhone and iPad

It is a calculator app that can be used in the notification center.
Since the call without having to switch the application,
I want to enable the quick calculation!
Since it is also compatible with sideways,
Handy when you wanted to calculate in a game app!

There are the following features.
- Simple UI that was in the Notification Center.
- There is a non-display mode, it does not occupy the notification area.
- You can resume from the calculation in the middle next time you open.
- In response to the landscape, you can choose left side, the right side.
