Designed for Use
Texas Calc'em has a clean and efficient layout:
The Five Community Cards are at the top
The next row holds the two Player Cards
A picker for the number of players at the table
A result table in the main section
A quick tap on a card brings up the card keyboard
And an intuitive Gesture based Edit:
Tap on any card, at any time to update your input
A up gesture on a card resets it for new input
A left to right swipe on the green, clears the table
