Offline RSS reader
Byline ($3.99 USD) is one of my top five used applications. This is a great app. For a long time Google Reader had become an exercise in frustration for me. Leo Laporte has said that RSS is dead, and before this app I agreed with him. If I didn’t read my feed in a few days it would be come downright unmanageable. I’d end up missing a lot of content because I got frustrated and marked massive amounts of my feeds as read when I hadn’t viewed them. If I tried to, I’d be tied to the desktop for hours. This application basically mirrors your Google Reader feed and allows you to cache them locally on your iPod. Now when I’m standing in line at the grocery, or any other place I have to “hurry up and wait”, I’ve got content to keep me occupied. There are many other options to Byline of which you can see in the review below. You can download Byline here.

IRC client
Colloquy ($1.99 USD) If you’re a geek like me and visit a few IRC chats regularly, this client based on the popular Mac IRC client hits the spot. You can download it here.

Mobile e-reader
Kindle for iPhone (free) is an awesome e-reader. The Kindle reader software is available on the Kindle, on PC, and on the iPhone/iPod. You can import your Kindle books between devices and sync the location of where you last left off on any of the three devices. Reading is best on the Kindle, followed by the PC, then the iPhone/iPod. Reading via the iPod wasn’t difficult, it was just a strain over long periods of time. This app, like the Byline app above, is perfect for reading when out on the go but you’re not going to want to curl up with it on the couch and read War and Peace. You can download Kindle of iPhone here.

Gym Goal ($7.99 USD) is an application that will help you when going to the gym to keep track of your workout. It’s a very advanced journal. It will record the reps, weight, and many other relevant data concerning your workout. It also has a database of exercises and corresponding animations on how to perform the exercise correctly. I already have my iPod in hand listening to music, so it’s only a little bit more of a bother to go into GymGoal and record each workout complete as I’m doing it. The only downside I see to GymGoal is the lack of a rich online recording mechanism and API. That being said, that’s the weakness of every exercise recording application I’ve found. GymGoal is better, hands down, to any other workout application I’ve used. The price is a bit high, considering the lack of online manipulation of data, but if you’re interested in recording your workout data, IMO it’s the best option. You can download it here.

WordPress (free) I have multiple WordPress blogs, and I’d love to have an application that would allow me to easily post to blogs, and maintain them. While this application is great for on the go moderation, as a blog editor, it really is lacking. For short posts this application is fine, but don’t expect to do full blog posts or major blog post editing on this app. Like the above mentioned Kindle e-reader, this application suffers more from the device limitations itself than it does from the app. You can download it here.

Grocery Gadget ($4.99) is an awesome grocery list application. I wish the developers of Gym Goal would talk to Grocery Gadget! Where Gym Goal fails as an application, Grocery Gadget kicks ass. You can maintain your lists via their website and sync them to your device. The app is very intuitive, learning not just what you buy, but in what order. The longer you use Grocery Gadget, the more useful it becomes. Watch the video below to fully understand the power of this app. Even though the acting is horrible, the application rocks. You can download it here.

CardStar (free) I love the concept of Cardstar. You load all the information you get from the “extra value” cards that retailers give you onto your device and use them instead of fumbling for the right card on your key ring. I just downloaded this application this weekend and will try it out soon. I’ve read in some places that it’s difficult for the scanners to read the device. I’ll post my results here after I’ve used this for a while. But it does seem promising. You can download it here.
