For those thrill seekers out there, LeapingFrogs came up with a clean little iPhone app that displays the speed at which the vehicle you’re on is traveling. How Fast requires an iPhone with a 3G connection, for best results.

By using location capabilities from your iPhone, How fast can calculate the current velocity and to display it, it uses a very readable speedometer on your screen. Easy to use, easy to understand. But pretty low on functionality. There’s basically just one thing you can do with this app: see how fast you’re going. There are a few options that come to mind, options like saving speedometer readings for later comparison, or, to give it a funny angle, funny comparisons between your speed and various vehicles (train, bus, car or space shuttle).

With Kensington’s free Rise&Shine iPhone and iPod Touch app, you can easily turn your favorite device into a nightstand clock with a retro or digital theme to enjoy on your occasional night walks. The application itself is free, and although there are several others that do the same job, the team over at Kensington added the novelty of including a stand to keep your iPhone fully charged at night.

The app is beautifully designed and loaded with neat options. You’re given three themes to choose from and then personalize to your likings: reflection, flip and digital. The display works in both portrait and landscape mode, and you’re free to choose whatever colors you desire for displaying the time. One extra added bonus is the local weather, which is displayed as well (in either Celsius or Fahrenheit degrees), plus the five-day forecast at the tap of a button.

Digits is the iPhone app from Smudge Apps that makes adding phone numbers to your contact list a breeze. It proves that perhaps the simplest of apps are the best of them.

Digits is designed to do one simple thing: add a person to your Contacts as fast as possible. It grabs the person’s phone number plus the contact name associated to it, and voila, the contact is already in your native Contacts app on the iPhone.

We’ve had this iPhone app in the queue for quite some time now, when Recorder Pro was available for free after changing its name from iDicto. We must apologize to the development team over at DAVA for not posting the review earlier, perhaps before the new OS 3.0 was launched, which includes the Voice Memo native app.

Reviewing Voice Memo from Apple is not what we’re going to be doing, but needless to say that all the nice functionality we get from Recorder Pro (previously iDicto) is available with Voice Memo. On to Recorder Pro, the app does exactly what it was intended to do, record voice memos, events, stories, what have you, of any length, depending on your free storage capacity. Starting and stopping a recording is simple, and is done simply by tapping the record or pause button. Each recording is assigned a date, time and length, and, additionally, you can choose to asig it a name, associate it with an icon to group several recordings together under the same icon, and even a priority level.

The winning app that surpassed all organizers the mobile generation was given has entered over a year ago on the iPhone, with an incredible track record in the AppStore. With Evernote reaching out to iPhone users, it didn’t take much for it to slide to the top and establish itself as the authority in productivity apps available in the AppStore.

Remember Everything. This is what the app promises and it does deliver. The team put at your disposal a desktop application, a browser plugin on top of the iPhone app, letting you capture anything from the web, daily travels, from written notes to recorded memos, from snapshots to clippings from the web. The app takes care of everything related to organizing the data and, on top of that, syncs everything between your iPhone, MAC or PC and the Web, so you’re always organized whatever you’re using and wherever you’re using it. It’s all automatically done for you, and, yes, it’s free of charge.

9 Toolbox brings together a very different set of tools, very useful otherwise, that open up new possibilities on you iPhone and iPod Touch. A currency converter, a date calculator, days until a special event, a holiday calendar, an inclinometer, a loan and a tip calculator, a unit converter and a menstrual calendar. Now isn’t that a curious bunch to come as an AIO?

The Currency Calculator lets you easily convert between worldwide currency, while currently supporting 164 currency codes. You have the possibility to update the exchange rate either manually or automatically, when you start the app.

The Date Calculator does more than math additions and subtractions. You have the possibility to calculate the number of days between two dates, add days to a set date, and find out ahead of time what day of the week the, say 19th of August 2037 will be (it’s a Wednesday).
