You just missed an important client meeting. Those notes from the conference? They're covered in spilled coffee. And you haven't changed the month on your calendar since … 2009. Throw all of those Post-Its away, pull out your iPad and download these apps. Once you're finished, you'll feel a glorious feeling wash over you. It's called being organized, and you might want to get used to it.
Noteshelf
$5.99 for the iPad
After downloading Noteshelf, you may never have to buy a paper notebook again. This app for the iPad allows you to take notes with your finger or stylus in 17 different shades of ink. Users can choose among several background templates, ranging from simple-ruled to day-planner to music notes. Highlight key points in your notes with more than 450 icons, or imbed — and write on — your own photos. Once you're done, you can share and print your notes easily, exactly as you see them on your iPad.
Todo
$4.99 for Apple devices
Forget that to-do list hanging on your refrigerator door or pasted via sticky note to your desk. The Todo app is meant to manage all of that for you. Users can set up multiple reminder alerts, create projects and checklists, set due dates on the calendar and share everything via email.

Use the extra space to keep an eye on your Facebook and Twitter feeds, your personal calendar or calculator tools. The app also allows users to provide a mirror image of slideshow presentations. Hand the tablet over to your client, and they can follow along while you click through the show on your computer screen.
