The fantastic Nike+ App let you track how far, how fast and at what speed you're running with only a sensor in your Nike-branded shoe and a compatible iPod or iPhone. Now you don't need the sensor or the shoe.
The $1.99 app, which just got posted to iTunes, uses GPS to track where you run-something the old version was lacking-but still includes the community features that made running not quite such a lonely affair. Now you can use the iPod touch2nd through 4th gen, and the iPhone 3GS and iPhone 4 with the Nike+ app. Only the iPhone works with GPS functionality unless you have something like Magellan's iPod touch case, which adds GPS ability (along with a lot of weight).
As a fan of the original Nike+ concept, I'm happy that this lets more people running in order to make it more likely that I have someone to challenge to a race.
PhotoShake!: There are plenty of apps that let you add all sorts of artsy filters to your iPhone photos (not to say that they aren't good! I use many of them!) but relatively few that offer you other ways to present your pictures. PhotoShake! does just that, allowing you to combine photos, add frames, stamp on speech bubbles and more. OKAY, so it may not necessarily put the hip in hipstamatic but maybe that's a good thing! $2.
Pizza Boy: Bearing not a small resemblance to a certain videogame plumber, Pizza Boy is an immensely likable old-school platformer with the rare button scheme that keeps you in control of your little pizza dude without your thumbs blocking too much of the action. Some people have complained about the short length of the game, though it's well-realized enough as it is (great soundtrack, too!) that Pizza Boy's worth it as a snack. $2
It's a fact: everyone sounds better Autotuned. Smule's I Am T-Pain app now lets you send autotuned voicemails to friends and family for a small fee. Because there's no better time than the present to start calling your Aunt "shawty."
The update is free for people who already own the popular app (which itself is on sale for $1 this weekend), though you'll have to buy T-Pain credits to leave the 45 second clips (they can be acapella "freestyles" or ditties on top of some non-T-Pain beats). $1 gets you 3 credits normally, though this weekend they're kicking things off by giving away 5 credits for a dollar.
If you're embarrassed by the prospect of sending someone you know (or, as the video above suggests, someone you want to get to know) a clip of yourself singing like T-Pain, the dialer lets you schedule delivery of the recordings up to 48 hours in advance. So practice and record your ballad while you're sober and able, set it to send to your prospective paramour at like 2am, and then blame it on the alcohol.
$1 this weekend!
iMovie: Apple's iMovie app got a little bump with the recent iOS 4.1 upgrade, including the very crucial ability to split video clips. How are you going to shoot the next Citizen Kane on your iPhone if you can't split clips!? The updates free for folks who have the app, otherwise $5
Guitar Jam Tracks: I have owned a guitar for many years but have never really moved past the scales roadblock. Guitar Jam Tracks is stupid simple way for you to practice your riffs and solos, letting you pick a key and play to a rhythm track while the app shows you which notes sound sweet on top of it. $1
App Shopper: Apple's App Store is a sprawling, unwieldy thing, and every day hundreds of apps go on sale without you even knowing it. Now there's a way to keep track of all those sales and freebies, right from your iOS device.
That app is AppShopper, the free, native app version of a useful app-tracking site of the same name.
AppShopper lets you set up filters and notifications that make Apple's largely unmanageable App Store just a little more manageable-you can just view, say, all the free games recently listed-but best of all it lets you see, at a glance, which apps have just had price changes. That means everything that's been put on sale or marked as free will show up right in the palm of your hand, ready for downloading. Good news for your app-loving self, bad news for those App Store receipts in your inbox. Free.
Markdown Mail: Markdown, a popular markup syntax developed by John Gruber for sending snazzy HTML emails, is a nice, simple way to get your emails looking nice for your friends and family. Markdown Mail is a clean, simple app for using that syntax right on your iPhone. It lets you preview your messages and look up the syntax in-app, and has text expander support. $2
