Some apps are almost universal. Chances are you may find a use for one of these apps in your daily goings-on, just as I have. All links are iTunes links.


Flicktunes, $0.99
Remember our chat about driving and using your iPhone? Flicktunes makes controlling the iPod in your iPhone (or touch) much easier when you have to focus on other things -- like driving. Flick your finger left or right to navigate your playlist, up or down to start or stop the music. The album art is all you see, plus a speaker icon indicating playback. It's super easy, a simple app, but very useful if you're driving or otherwise occupied while jamming out.

Army Knife, $1.99
If you need to measure something in a jiffy, Army Knife is a 9-in-1 tool with several measuring tools. There's a protractor, a caliper and a tape measure, plus a level and a "heart monitor" (you tap as your heart beats). There's a unit converter with distance, volume, weight and temperature conversions, and a flashlight and whistle. The flashlight, yes, is just a screen of white, but the whistle is kind of fun and will irritate your pets (please note: I do not condone irritating your pets, please do not flame me for hating animals).

Todo, $9.99
If you use Remember the Milk or Toodledoo, you should know that Todo syncs with them. There's also a free sync app for your desktop, which is essentially a backup... except there's a way to sync Todo with The Hit List via iCal. Is it optimal? No, but until THL has an iPhone app (not criticizing the developer as I'd rather it be done right than fast) this does the trick to an extent. Todo even without sync is a beautiful thing to behold and full of flexibility. In fact, the flexibility of the app is a little shocking, given the lowly status of the "to do" genre of apps. If you need a listmaker/to do/checklist app with or without sync capabilities, this is one of the best out there. Worth the $9.99 for what you get.

CardStar, free
If you're tired of carrying around a dozen membership or discount cards, CardStar will help you out. There are templates for many retailers and discount systems (air miles and so forth), and you can choose from a variety of barcode types. I was able to experiment with the codes a bit and test things at each of my errand stops (Blockbuster, Kroger, etc.), eventually winnowing my keychain down to just 2 keys and a door opener.

BigOven, free
I've toyed around with a few cooking apps, but if you're out and about (and have a signal) BigOven is a great way to throw a dish together based on an ingredient. BigOven basically makes everyone an Iron Chef -- at least as far as cool recipes goes. It can't help you cook things, and the text rendering could be a little more clear, but you can favorite stuff (with a BigOven free account), and copy an entire recipe for emailing. I'm not saying the interface is great, but the BigOven database is huge and stocked with what looks like good recipes.

Let's face it, the less distractions you have while driving the better, even if the government can't decide whether or not to tell you how dangerous phones + cars can be. Last week I was happy to see Penn Jillette (a magician whose work I've admired since I was too young to say the name of his current show) on Twitter proudly announce he was going to quit calling and texting in the car. Bravo!

Penn happens to sport an iPhone, and like any modern cell phone, it has "airplane mode." I'm going to show you how to set the iPhone to this "no call" mode, and explain why you probably don't have to while driving. Plus, if you absolutely must talk while driving I'll explain a helpful trick with the 3GS. You should never under any circumstances try to type while driving -- pull over, already.

To turn off your iPhone's cell radio, thus preventing distracting text messages, push messages and phone calls, go to Settings > Airplane Mode and turn the switch ON. Pretty easy, yes, I know. But unless you are going to use the iPhone's audio in your car (and there's like a zillion apps for that), you could just as easily turn off the ringer. The switch above the volume buttons on the left of the screen controls the mute for external sounds. When you arrive at your destination, check your phone for missed calls, etc.

If you have a 3GS, you can use the Apple headphones that came with it to activate Voice Control, giving you a relatively safe method of interacting with your iPhone while driving (except for a proper, Bluetooth speaker/mic or in-car solution, I guess). Plug in the headphones and put the headphone directly connected to the microphone in your ear. Press and hold the "middle" button (in-between the volume buttons) for about 3 seconds, until you hear the beeps. Voice Control is now on! You can control the iPod functions and make calls, but I recommend you try Voice Control before you start driving. Note that there are voice dialing apps for previous iPhones, but I feel having to see the screen to push even one button is an unacceptable distraction.

The New York Times and many other news outlets have reported on the unreleased government study showing that even talking on the phone increased the likelihood of having an accident -- whether you are hands-free calling or not. Driving and chatting with a disembodied voice can be distracting, apparently. So, again, the only truly safe thing to do is to switch off your cell radio entirely (Airplane mode). This won't allow you to play streaming radio stations, but it may save your life. Otherwise, use your willpower to ignore the chimes, rings and buzzes, and if you absolutely must talk or text, pull over.

Grant Robertson at The Digital Music Weblog (a sister blog) has dug up details on a move from the Canadian Automobile Association to pressure provincial governments in Canada to ban younger drivers from using electronic devices, such as mobile phones and MP3 players, in the car, eh. While some think they have their song switching skillz down pat while juggling a Big Gulp™ and steering with their knee, Grant also cites a study released in April 2006 by the National Highway Traffic Safety Administration that states "the many forms of distractions are collectively responsible for as many as eight out of every ten crashes" (do y'all even have 711's and 'Big Gulps' in Canada? If not, consider yourselves lucky).

Check out Grant's post on the issue covering more on this sudden iPod-hating from Canada (we kid). But if the thought of not being able to cart your tunes with you is too much to bear, you might also need to start checking up on those fancy iPod-integration kits that let you control your iPod from your steering wheel.
