There are hundreds of thousands of iPhone, iPod touch, and iPad apps for just about everything -- so how come the one you need, the one you know just has to be there, is so hard to find? Enter TiPb's new weekly feature where staff and readers alike sort through the App Store and help you find just the right App for That. This week, Aatif asks:

I'm writing as a freelancer for a blog, and I was wondering if there was an app available that can help me keep track of how many posts I have written in a pay period as well as amount earned for each.

To see what we found for Aatif, follow along after the break!

Invoice2Go [$9.99 - iTunes link] is a fantastic app for creating invoices on your iPhone. After setting up your business (your personal info for freelancers), you're ready to start invoicing. Under the products tab, you can add the different services you offer, or in Aatif's case, various types of articles that he writes. When creating an invoice, it's simple to add the saved products and specify a quantity. When finished, Invoice2Go totals everything up and creates a beautiful invoice as a PDF that can then be emailed to your employer or printed over AirPrint.

Invoice2Go offers many different templates for the final invoice design and even includes the ability to add a custom logo. You can also add a PayPal button to your invoices. This may not be ideal for Aatif's situation, but could be great for those of you creating client invoices.

If the price is a little steep for you, Invoice2Go Lite [Free - iTunes link] is a free version of the app that restricts you to only keeping 3 invoices at a time. This sounds perfect for Aaatif as long as he emails a copy of the completed invoices at the end of each pay period. Invoice2Go Lite is also a great way to try out the app and determine if it will meet your needs.

Bonus app: iSpreadsheet

If Invoice2go has more features than necessary, and you find that less is more, you can create your own spreadsheet with iSpreadsheet [$2.99 - iTunes link]. This type of report is very simple to create and may be a more desirable option. For the budget conscious blogger (the prices in the screenshots are from my fantasy world), iSpreadsheet Free [Free - iTunes link] is ad-supported and has all the features of its paid version.

Anyone else have any App for That suggestions for Aatif? Let him -- and all of us -- know in the comments.
