I’m super excited to announce a first on DemoGirl (insert suspenseful drum-roll here). App Happy: iPhone App Reviews for Everyone.  Or something like that.  Ok, so now that I got that out of the way, and you’ve all had a chance to put on a fresh pair of underwear, let me explain:

This past weekend I got my hands on an iPhone, rigged up a mini-iPhone recording studio, and went to work.  I chose the WordPress iPhone App because I use WordPress on a daily basis and, in all seriousness, it is a super useful App for anyone who uses WordPress.

Technically this is not a screencast.  But, I am recording the screen of the iPhone and our mission remains, to help everyone understand and see how to use fun and helpful applications – Web-based or, now, mobile.

Please watch the video below and let me know what you think in the comments.  Is the lighting terrible?  Is it too hard to see the iPhone in action?  Am I in desperate need of a manicure?  Or do you think this is the most amazing thing you have ever seen in your entire life?  Your feedback is so important to me and I thank you in advance.

When I logged into Gmail this morning I finally saw what I really wanted to see yesterday afternoon – “Buzz”.  It was right where everyone said it would be, under my inbox tab.

After spending a few hours poking around and (unsuccessfully) searching for some help topics on exactly who can see what, I think I finally got the gist of Google Buzz. Oh, and just in case you’re wondering, I like it. I like it a lot.

If you’re a freelancer you may find it hard to determine a fair hourly rate to charge your clients and still make a decent living.  You don’t want to overcharge because you need to remain competitive – however, if you undercharge clients you won’t be able to to do things like pay rent and buy groceries.

That’s where the FreelanceSwitch Hourly Rate Calculator comes in.  It helps you calculate what you spend annually on business expenses, personal costs for things like rent and car repairs, and how much you want to put into savings each year.  It combines this information with how many days and hours a year you work, along with the percentage of hours you can actually bill people, and spits out an estimate of how much you should be billing your clients.

1DayLater is an application that allows you to track the hours you work on projects, the distance you drive everyday, money you spend on groceries, hours you put in at the gym, and anything else you can squeeze into a day.

Using 1DayLater is extremely easy – Enter in hours, mileage, or money spent and then a project/client name and description.  A project/client name could be for anything you want to track, so if you’re tracking how much you spend at Whole Foods every week you would put “Whole Foods” into the project/client field.  Lastly, add the date and click on “Go”.  This activity will be placed into your activity stream for that day and the amount you entered will be added to any other day that you created an activity for that project.

You can view a graph that shows just what you’re spending your time on and export your data for further use.  Future features include invoicing information and mileage calculation.

MemorizeNow is yet another application that I wish existed when I was still in school.  It helps you remember short and long  phrases of text by training your brain how to read the phrases with different words removed in each sequence.  This can be used for something as simple as word definitions to long speeches or poems.

It was initially created to aid in memorizing passages from the bible, but obviously it can be used for just about anything you need to remember.

I finally got around to checking out Google Search integration with Gmail today and it turned out to be more useful than I had anticipated.

You see, I’m getting ready for my Mom to come visit me in San Francisco this weekend and now, instead of copying and pasting numerous Google search results of places we should check out into an email, I can simply start composing my email to her and then do Google searches within that message.  The search results can all be pasted right into the email, links and all.

You need to go into your lab settings first and enable Google search and make sure your rich text editor is enabled.  That’s all there is to it!

Repper is a fun tool that helps you create fancy patterns out of any old photo.

All you need to do is upload a photo and then use the Repper tool to create crazy patterns.  The image above is what I created and then added to my Twitter profile page.  You just need to be sure to use a “tile” background option to make the pattern look right.
