QuadCamera - Multi Shot Cam

Here's a fun addition to your iPhone camera app arsenal: QuadCamera ($1.99, available here) which takes four shots in quick succession. If you like to photograph action sequences, such as a sports competition, you'll enjoy seeing how the scene changes from one shot to the next. We tested it with our pets and with people on the street, and the results were just as fun.

One of the best things about the app is the range of settings. You can set the interval between shots, so that all four shots are taken in rapid succession or with as much as three seconds between them. You can also choose to view the results in a horizontal two on two configuration, or vertically with all four in a row. Shoot in color or black and white, if you prefer.

We found taking pictures with QuadCamera to be just as simple as using the iPhone's built-in camera app, and the results were oddly fascinating. If you're looking to do more with your phone's camera, give this inexpensive app a try.

Hot or Not

This app makes us nostalgic for 10 years ago, when ratings sites caught on and we were suddenly spending free time judging people's faces, bodies, cars, and even pets. Apparently the best known rating site, Hot or Not, is still around, and it's just created this fun little diversion.

Hot or Not (available here) invites people, typically attractive young people, to post their photos online for others to judge. You rate each face from 1 to 10, and then you can see how your rating compares with that person's average score.

The site branched into a hook-up stop long ago, so if you're on the market you can try to meet your crushes. We didn't test that part.

Now, the app is far from perfect. You can enter your preferences for whom you'd like to rate (male or female, age range, and so on), but it won't remember your settings from one session to the next. Also, it crashes reliably after a few minutes of use. But for a simple time-killer, a few minutes is all we need anyway.

White Noise Storm

Do you sleep better when it's storming out? The creators of the sensational White Noise now present White Noise Storm ($.99, available here) a sound-creation app that lets you produce your own perfect storm. Choose light or heavy rain, the speed of the wind, and the intensity of thunder. Randomized effects make sure no two storms are alike, and a timer lets you get as much storm as you want. The app even saves your settings for the next time you use it.

Audiogasm

Free for a limited time, Audiogasm (available here) is a music visualizer for your iPhone. Relax with some songs and let Audiogasm's hypnotic visuals fill your screen. If you see a pattern you like, you can swipe your finger across the screen to take a picture, which is then stored in your photo album. If you don't like what you're seeing, shake your iPhone to change the animation.

WiPix

With WiPix ($1.99, available here), you can view all the photos in your photo library's camera roll album (meaning the shots taken with your iPhone's camera) on a computer Web browser as long as you're on the same Wi-Fi network. Open the app and it gives you an address to type into your browser. You'll then get a simple Flash interface that lets you scroll through your photos and download the ones you want. If the app could browse all the picture on your iPhone, it'd be perfect.

RepairPal: Auto Repair Expert

Whether it's an auto emergency, a roadside breakdown, or just a small malfunction, RepairPal can help. This app (available here) tells you the right price to pay for your repair, finds you a great mechanic in the area, and gives you one-touch access to roadside assistance. Even better, it covers every zip code in the country.

iNap: Arrival Alert

Train commuters, you know how easy it is to fall asleep on the trip home and miss your stop. But you don't need to worry when you've got iNap ($.99, available here). Just use the Google map embedded in the app to show where you'll be getting off, then take a nap. As long as your iPhone can get GPS reception, the program will track your location and trigger an alarm at preset distance before your destination.

DanceDanceRevolution S Lite

The dancing game phenomenon has finally reached the iPhone. Just place your iPhone on the ground, step lightly on the screen … No, of course now. You play DanceDanceRevolution S Lite (available here) by tapping the screen to the rhythm. Time your taps to the arrows that scroll up from the bottom of the screen. A full (paid) version will soon be released with new songs and characters.

Year of the Ox

Celebrate the lunar new year with Year of the Ox ($.99, available here), a colorful arcade-style game. Since the year of the ox is following the year of the rat, you play as an ox defending your turf from greedy rats. Use the iPhone's tilt controls to charge around and stomp rats, then use the stampede mode for extra power. The app also include a celebratory fireworks simulation. Gung hey fat choy!

SitOrSquat

Have you ever had to go to the bathroom desperately and not known where the closest toilet was? Now, there's an app to help you find one. SitOrSquat (available here) uses the iPhone's built-in GPS ability to search based on your current location, and then it gives you a map of the address. In our testing, we saw few bathrooms listed for our area, but that should improve as users upload new locations.
