Get your mind out of the gutter, I don't mean that kind of g-string! gStrings is a chromatic tuner for stringed and wind instruments but with some serious customizable features to match the exact frequency, octave and intensity you want. For no money at all, you can enjoy the most detailed instrument tuner I have yet to own. You can optimize for whichever instrument you're tuning, adjust the microphone sensitivity, and playback octave, along with advanced features like applying a harmonic product spectrum, enable FFT rounding, choose a specific tampering function, and adjust for orchestra tuning. So if you're a sonic genius or completely tone deaf, this one's great to keep handy!

I've got a toddler and time to kill. Air Hockey sounds perfect: classic table game ported to the iOS. But can sliding a finger in Acceleroto's Air Hockey come close to the full on joy of Air Hockey in the arcade? Watch the video to find out!

Hands down favorite app right now is Instapaper, Available on the iPad and iPhone. We social networkers get bombarded with links all day and that can screw up your workflow. With Instapaper, you just click on a read later tab you add to your browser and catch up later with text only versions of the article.

I LOVE music. Especially when my playlists are put together like magic with no awkward song changes. I've raved about Moodagent for the iPhone before, but the new version is even better with smart rhythm algorithms, and the ability to spread the word about great tunes with Facebook and Twitter. The new app is definitely an investment at $4.99, and there's still a free ad-supported version. But maybe you'll like it enough to pony up and support this great concept.

Gotta love Seacrest. As if he isn't ubiquitous enough, he's now got an app that streams the latest hits, workout jams, and 90's classics to your iPhone, iPod Touch and iPad - if you're into that sorta thing. It's perfect for the gym, and free for 60 days; at which point you can purchase it for $1.99. For pop music lovers, it's a download.

I complained about the price tag when I originally reviewed this, but after using it this past baseball season, I can't live without it! It keeps me up to date on the scores and standings, so I can see how badly the Mets are doing.

While the phone still sucks for making calls, it does take awesome 720p HD video. However, if you try to upload the video directly from your phone it gets compressed. Enter Pixelpipe - the awesome media gateway that WILL upload your video to Twitter, YouTube, Facebook and other social media platforms as 720p. Even better, it's free and a definite download!

The most impressive thing about ScanR is it's ability to create genuine Adobe PDF files out of pretty much anything. I took a snapshot of a printed document in relative low light, ScanR quickly archived the raw image, but also converted it to a PDF and used an optical character recognition (OCR) engine to captured 100% of the page as searchable text. Pretty cool.

Air Video is an app that lets you stream any video from any computer on your home network directly to your iPhone, iPod Touch or iPad. Just install the free Air Video Server software to every computer you want to stream from. Launch the app while your device is connected to the same network and you're good to go! AirVideo can play any video format, and if the video you're trying to play isn't compatible with your iPhone, iPod Touch or iPad, it will convert the video on the fly and stream it to you instantly! The only drawback is that it won't play your iTunes purchased or DRM protected videos. If you've got huge library of videos, tv shows, or movies on your computer, then this app is a must download!
