The Powerful Basics

Judy's TenKey records your calculations in a scrolling list which you can annotate, save, print, copy & paste, modify, reuse, and resize. You can customize Judy's TenKey in a myriad ways, but even more importantly, it intelligently tries to anticipate your desires and help you get your work done with minimal effort (auto-numlock, smart copy & paste, smart edits, etc.)

Smart Edits

Make changes directly to the tape and watch your totals automatically recalculate using our innovative “smart recalculation” (intelligently recalculates derived dependencies). You can also add or delete entire tape lines. A real time-saver!

Judy's TenKey Calculator Smart Updates

Multi-Level Undo

If you find you've done something unintended, just use the "undo" icon to undo your last entry, multiple times if necessary. You can also "redo" multiple "undo's" if you go too far! Super-easy to use (with Ctrl+Z shortcut) and a real time saver.

Reuse Calculations

For repetitive or similar calculations, highlight the lines you want to reuse and press the <Use> button (saves typing time and reduces errors).

Intelligent Copy & Paste

Judy's TenKey lets you quickly use numbers in other Windows applications, or paste results into a report. In fact, Judy's TenKey is so smart that it can sift through a document looking for numbers and automatically add them up (so you don't have to waste any time laboriously copying individual numbers). Very handy! While all of this is automatic, you can also provide fine-grained control if desired, and can save your preferences and use special toolbar buttons to use your fine-tuned copy & paste commands at press of a single button.

Choose Your Layout

You can decide how you want your TenKey to look (selecting from numerous functions), enabling you to optimize screen usage. You can also place the tape on the side, on the top, or even choose not to show it all. Any TenKey function can always be activated via the keyboard regardless of the current display configuration.

Your Perfect Calculator

No matter who you are, no matter what you do, Judy's TenKey gives you the software calculator you've always wanted. Why? Because Judy's TenKey lets you design it yourself...

Configure Judy's TenKey Calculator

Select Your Syntax

Judy's TenKey can process numbers like a scientific calculator (RPN), an adding machine, or a normal calculator. Unlike other calculators that make you pick a syntax and stick with it, Judy's TenKey lets you use any feature with any syntax. How many scientific calculators have you seen with a tape? Or adding machines that could calculate your mortgage? Judy's TenKey provides the ultimate in refined flexibility. If you are familiar with one and not another, you know how difficult and frustrating it can be to try to switch. Perfect for accountants, engineers, and everyone else!

Choose A Decimal Setting

You can set Judy's TenKey to display the number of decimal positions you prefer, ranging from 0 to "as needed". In fact, you can configure Judy's TenKey to automatically insert the decimal point for you (a real favorite with professional accountants). If you frequently deal with money, you might want to set the decimals to 2 (for cents) or 0 (for dollars).

Keyboard Calculator Key

If your keyboard contains a dedicated Calculator key, Judy's TenKey will automatically link to that key, and bring up your calculations in progress whenever you press it (not simply launch a new calculator as the default Windows calculator does). Press the key again to hide Judy's TenKey. Simple!

Item Counter

Optionally keeps track of the number of items you included in your calculation, showing a running count in the status bar and the relevant counts on subtotal and total lines.

Keep On Top

You can set Judy's TenKey to stay on top of all other windows, so you quickly make calculations even when editing a document full-screen.

Popup Tooltips

Rest your mouse over an item and see the meaning of the button, the keyboard shortcut, the contents of the memory, and so forth.

Adjust Your Keypad

You can swap the meaning of <Enter> and <+> on your keyboard to better mimic the keypad layout of a desktop adding machine (another real help for accounting professionals who are touch "typists"). Judy's TenKey can also automatically set your numlock whenever you type into the calculator, leaving your numlock unchanged for other applications.

Optional Sounds

You can set Judy's TenKey to play "clicking" sounds with each key pressed, providing audible feedback to ensure proper typing (plus, it's fun!).

International Support

Judy's TenKey uses Unicode to enable you to enter notes in any language desired, and your Windows settings to determine the character to use for digit grouping and for the decimal point. Please email sales@judysapps.com for availability of user interfaces in different languages.

Zero Install Deployment

Enables you to create a zero-install version so you can run Judy's TenKey from a thumb Flash drive or even a CD without installing anything on other computers. Great for traveling accountants or Internet cafe users!

Windows Versions

Judy's TenKey is available for virtually any version of desktop Windows, beginning with Windows XP on through Windows 8+. It automatically takes on the look & feel of whatever version of Windows you use, so it meshes seamlessly with your overall computing experience. For example, compare Judy's TenKey running on Windows 7 versus Windows 8:

High DPI Interface

Beginning with Vista, Microsoft Windows enables you to "magnify" the screen so that everything looks larger and easier to read: it's great for people with aging eyes, visual disabilities, or just tiny-looking displays. It's available by right-clicking on the desktop and selecting Personalize > Display. Unfortunately, if the program doesn't support it natively, you can end up with blurry-looking images.
