WordPress – Free – As mentioned above, it is by far my most used top office iPad app. However, I’m a writer so therefor I’m on it constantly. The only shortcoming is the lack of quickly inserting links, which you have to do manually. Other than that, logging into your blog, writing posts, insert images, creating pages, checking stats and comments has never been easier.

Skype – Free – With travels and oversees clients, I’ve found Skype to be the industry standard for connecting on the cheap. Just think how big your phone bill would be if you had to take an hour long international conference call. No thanks. Everyone has Skype now days and it’s easy as pie to use. Better yet, it’s free.

Square – Free with transaction fees – If you’re in a position where you need to setup a mobile register, this app is just the ticket. I’ve used it multiple times to accept payments from photo clients and other new business clients. It’s like a little register in your pocket and the latest update allows you to track popular items as well as use it as an actual register. Thanks Twitter co-founder. A must have free office apps for iPad 2.

PayPal – Free with transaction fees – Since I run a few websites that have goods for sell as well as the fact that I write for a few other sites that require I use PayPal to accept payment, this app is very useful for creating invoices, requesting payments and transferring money between accounts. More importantly, it’s safe and secure.

Stickies – Free – Are you a lover of Post-Its? Do you find sometimes you wish you had a digital version of them? Well now you do with Stickies and they’re free. Type notes, select colors, rearrange on the dashboard… simple and easy.

MailChimp – Free – One of the most powerful newsletter tools. And it’s free for us small newsletter writers. The ability to manage subscribers and track your campaign performance is absolutely awesome. And as you grow so due their services, albeit with a fee, but the free version is amazing and very robust.

Jumbo Calculator – Free – Everyone is in need of a calculator every once in a while and using the small keys can be ridiculously frustrating. However, this app allows you to take up the entire iPad screen with jumbo keys for effortless calculations.

HootSuite – Free – As Twitter has grown into a must for everyone so has the amount of third-party apps to harness the marketing and communication power of the service. I’ve found Hootsuite to be the easiest platform to use. I manage multiple accounts for myself and clients and have found it easy to work between accounts without getting to confused as to which account is which. The extended version has even more power. One of the TOP free office apps for iPad 2.
