App Zapper
Everybody loves the drag and drop nature of OS X. Drag an app into your Applications folder, and it’s installed. You’d think uninstalling would be just as easy dragging it to the trash. But it’s not — applications install preferences, caches, and other support files throughout your computer that take up space and generate clutter. App Zapper automates the process for you, because deleting these by hand every time you delete an app is a pain. Free alternative
AppDelete.

What Does it Do:
AppZapper is a way for the anal-folk amongst us to feel confident that when we remove programs from OSX we are getting all the nasty remnant files as well. App Zapper does this well.

Who Makes it: Austin Sarner and Brian Ball.

Awaken
Choose a playlist, pick from either a weekly or specific date alarm, set the time, and enter a reminder note if you wish — and you’re done. The volume of the music can be set to fade from 0% to the desired level over a specified number of minutes to gently wake you from a peaceful slumber without a sudden jolt. You can also use the sleep timer to fall asleep to your favorite iTunes playlist. The volume can be set to slowly fade to 0% as you fall asleep. Once the timer reaches the end it can put your Mac to sleep and later wake itself at alarm time. This might be the greatest thing since the Snooze Button. The free alternative
Aurora.
