Numeric is a multi-touch calculator for your Mac.

Instead of pointing-and-clicking with your mouse, Numeric is a calculator with keys you can touch directly. The keys on Numeric's keypad are mapped to the same locations on your Mac's multi-touch trackpad. So to press a key, just tap it on your trackpad.

Known Issue in Mountain Lion:

Sometimes the keypad can become unresponsive in Mountain Lion. If this happens, swipe down with two fingers on your trackpad.

Numeric works on any Mac with a multi-touch trackpad, which includes:

• MacBook Air (Late 2010 and later)
• MacBook (Late 2009 and later, or the Aluminum MacBook)
• MacBook Pro (Late 2008 and later)
• Any Mac with Magic Trackpad

In other words, if your trackpad does not have a physical button on it, it will work with Numeric.

Additional features of Numeric include:

• Delete button (top right corner)
• Undo and redo for all actions (Command-Z)
• Scientific notation
• Local number format

What to Expect:

Since you cannot see the number you are pressing on your physical trackpad, do not expect 100% accuracy from Numeric. However, with a little bit of practice, Numeric should be faster than a traditional, point-and-click calculator app. Also, you can always undo or press the delete button if you accidentally hit a wrong key.
