RedCrab - The Calculator
Solve complex equations in seconds with this powerful calculator

RedCrab is a versatile scientific calculator with a host of powerful features.

The program allows you to work in a very natural way, for instance, entering formulae in a full screen editor. You're able to enter complex equations with fractions, exponents, integrals, square roots and more. And you're not restricted to just one: the program will accept several equations on the same page, with the result from one being carried to the next.

If this sounds complicated, then it can be, depending on what you're doing. But RedCrab is generally very smart about how it interprets your expressions, and in most cases it'll figure out what you need first time. And when it does, you can then save and load complex formulae for easy reuse later.

You don't have to get involved in complex math every time you use the program, though. RedCrab also works well for more basic calculations. And it's portable, too, so if you need to do math on the move then there are few better options - just install it on a USB flash drive, then call up the program when you need it, on any convenient PC.

Version 5.5 (Changelog):

    - RedCrab 5.5 runs with Microsoft Framework 4.0 (before only 4.5) and can be used also on Windows XP.
The manual is available online and can displayed from the program. Right mouse click on buttons or menus open their description.
    - Editor improved, scrollbars errors fixed, page-up, down installed, cursor control improved. Paste with CTRL + V installed.
    - Load Microsoft Excel files.

If even Windows 7's revamped calculator isn't powerful enough for your needs, give RedCrab a try - it's smart, and packed with useful features.

WhatsApp Messenger 2.12.11

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.11 brings:

• Links that you share or receive will now include a rich preview. When sending a link, you have the option to not include a rich preview.
• Additional 3D Touch features: You can now quickly Peek and Pop chats.
• Redesigned Settings tab. 
• You can now view all your starred messages across all your chats in Settings — Starred Messages.
