I wouldn’t have guessed that pigeons are so inquisitive. Or so persistent. My kids and I have prevented this particular pigeon from staying up late and from driving a bus. We’ve helped him share his hot dog and talked him out of getting a puppy. Now, we’re preventing him from running an app…although there’s really not much app here to run.

iMapMyFitness is pretty much your usual iPhone fitness app. It utilizes the iPhone’s GPS technology to keep track of your running course. The developers describe their app as your personal training log and friend. True enough; it not only tracks your running course, but it also lets you keep a log of your gym workouts.

I first met with and heard about Runmeter at Macworld 2011. I was quite impressed at their booth as they walked through some of the features of the application with me. In terms of running applications, it definitely seems the easiest to understand yet most feature packed I’ve seen. It is definitely worth the $5 if you run with your iPhone but aren’t doing anything beyond using an old fashioned watch to keep track of your stats.

Twisting 3D objects in space with ease would only really be possible if you could use the Force, young Jedi. Unfortunately, none of us can, despite how hard we may try. Thankfully, there’s now an app that allows you to simulate this task on your iPhone! Man, those things really can do anything. 3D Twist and Match is exactly like it sounds…

I find something liberating about all of these photo effect apps for the iPhone. Being an avid Photoshop user, I’m used to getting exactly what I want out of an image if I’m willing to work at it long enough. That type of power and control is not available on an iPhone app, of course, but that makes it more fun to play around with. And when it comes to iPhone photography and manipulation, few are as fun as Camera Plus Pro.

I absolutely love the premise of this app. In fact, it’s the second such app I’ve tried out, and it’s the second such app to leave me somewhat disappointed. Ghosted, you see, allows you to add ghostly images to your iPhone photos, whether they’re taken through the app or pulled form your library. It’s a cool and quite creepy effect when done right, but Ghosted doesn’t always allow you to do it right.

Agendus makes a pretty big promise to its users: total integration of your contacts, calendar and task list on your iPhone. It’s an enticing idea, to say the least. After all, organization helps us to get things done. Unfortunately, as with so many other big promises, Agendus falls short, mainly due to a poor user interface, an ugly design, and its bad habit of crashing.

uSketch is a free iPhone app meant for lightweight editing of images. Instead of applying color changes and drawings to your image, this app simply applies filters that make your image look like a sketch. While the filters for the most part look the same, some include color while others are black and white. I can’t say it’s contagious, but considering its free price tag, you can certainly try it out with no monetary loss.

I had high hopes for iShred Live. It’s the app partnered with Griffin’s GuitarConnect cable. I found the cable to be the best choice available for guitarists since it was fairly priced, designed well and still had audio quality similar to the iRig. So, I thought maybe this combo was on a roll, maybe the app was going to do great things at a lower price, just like the cable. It just wasn’t meant to be.

Springpad is a free service meant to give users complete control of the information, plans, and tasks they come across in their daily lives. With ways to keep track of anything from planning a date night to saving recipes and keeping track of movies you want to see, it is quite an extensive application. That said, the core of this service lies in the web, and the iPad and iPhone clients just serve as easier ways to access and store this information.
