coconutBattery isn't just a tool which shows you only the current charge of your battery - it also shows you the current maximum capacity of it in relation to the original capacity your battery had as it left the factory.
You also get information about the battery-loadcycles (how often did you fully load your battery), the current charger (coconutBattery even warns you if you plugged in a wrong charger for your Notebook) and last but not least information about the age of your Mac.

coconutBattery gives you all these information just in time because of it's live-feedback interface!

smcFanControl lets the user set the minimum speed of the build in fans.
So you can increase your minimum fan speed to make your intel mac run cooler.

However in order not to damage your machine scFanControl let's you not set minimum speed to a rate under Apple's defaults. In addition to that fans are still in automatic mode, so the speed of your fans will increase, if CPU load gets higher.

• Displays temperature and fan speed in the menubar

• Apply different fan-settings with just one click

• Let's you set different minimum speeds for every fan seperately and save them as favorites

• Autoapply different fan settings when the powersource changes (macbooks only)

• Sourcecode included! Extend it and change it to your needs

                                                 



Personal Note: I constantly have this application running, it eases my ming to just my menu bar and it tell me at what speed my fan is running at and the current temperature reading. Very simple but accurate.
Recommended.

AppDelete is an application for Macs that will delete the application you choose and any associated items (files and folders) that belong to that application. Now you will no longer have to hunt through your system to find these items and delete them manually. Or worse, just let them sit on your Mac forever even though the application is long gone!

                                      

Personal Note: I myself use AppZapper which is not freeware but AppDelete is just as good, it is receiving some great reviews. It is a great timesaver and it fits right in the dock so it is out of your way.

Carbon Copy Cloner

The key to a successful backup plan is to actually do the backups regularly. When left to a human, the task often gets tacked on to the end of a very long list of other things to do. When you eventually have a catastrophe, the data is simply gone. You know that feeling -- you just lost six years of family photos. Your kids being born, their first birthdays, their first everything. The answer to this is consistent and regular backups, placed on a schedule and handled automatically by your computer.

Among the new features are:

• Support for block-level disk-to-disk clones.
• Synchronization built-in, not bolted on.
• Support for backing up across the network to another Macintosh.
• Advanced scheduling capabilities -- Backup tasks can now be scheduled on an hourly, daily, weekly, or monthly basis, or you can indicate that a backup task should run when the backup device is attached (e.g. an iPod).
• CCC recognizes iPods specifically, allowing time for the iPod:iTunes synchronization to complete.
• The ability to drill down into folders to select exactly what gets copied and what doesn't (you can drill down indefinitely).
• Built-in software update feature notifies you when updates are available.

ImageWell is a small, but powerful, image editing application that lets you quickly

resize, crop, watermark, edit your images, take screenshots and then upload them

to the web, save to your computer or email them to a friend. ImageWell also lets

you annotate your images with text, shapes, arrows and lines, quickly and

easily. And it doesn't stop there - add a drop shadow, a shaped border, flip or rotate

your image, plus so much more.

Don't want to send your image to the web? You don't have to, it's not the law. Edit

your image, give it a name and file type, and simply drag and drop the image to the

desired destination on your computer to save it there. Or drag and drop it into an

email message, a document or presentation. Want to send other types of files to

the web - you can do that too. It's easy-shmeasy, just choose the location, and

drop the file over the Send button...done.

                                       

Personal Note: I love this application, it is very handy and quick.   Everything is right in front of you for quick access and is very user-friendly.  Recommended!
