Four Must-Have Apps For IPhone 4

The iPhone 4 arrived over the summer, and although it’s been a long wait, developers are finally releasing new apps that take advantage of all the cool new features available only in the iPhone 4 device. This means that iPhone 4 owners can download some of the coolest apps that can’t be found for any other device.

Here is our list of the best, must-have apps for the iPhone 4.

LED Light for iPhone 4 Free (Free, Jason Ting) Remember all those awful flashlight apps that flooded into the App Store seemingly moments after it was opened up to developers? They all used the screen as the light source, and some of them even had the audacity to cost money. Thankfully, LED Light for iPhone Free uses the ultra-bright LED flash of the iPhone 4 to guide your way when you need it, and it doesn’t cost a thing. There’s a paid version if you want to avoid the iAds, but this free version has all the features: strobe light, sleep timer, and a few others. It’s the only flashlight app you’ll ever need.

IncrediBooth ($0.99, Synthetic Corp) Here is an app that takes the iPhone 4’s front-facing camera and turns it into something that is as awesome as it is inevitable: a retro, dive-bar style photo booth. Cram as many friends as you can in front of the iPhone and it will take a series of rapid-fire pictures, apply some nice film grain and vignetting, and save the shots as a long strip, just like the real thing. It’s not just an idea so perfect you’ll wish you thought of it, it’s a fun, inexpensive camera app that’s executed perfectly.

GyroSynth for iPhone 4 ($0.99, BeepStreet) Unfortunately, GyroSynth will not generate authentic, Greek-style gyros. While You Gotta See This! uses the accelerometer to take awesome pictures, GyroSynth uses it to make awesome music. To use GyroSynth, just waive the phone around and, just like a Theremin, the roll and pitch will translate into sound. After a short learning curve, you’ll be able to make music with a fluid series of gestures. GyroSynth comes with tons of features and recording options, so it’s sure to be a hit with amateurs and professional musicians alike.

The Elements for iPhone 4 ($9.99, Element Collection, Inc) The Elements for iPhone 4 is an educational app that– wait, don’t run away! Sure, The Elements might teach you a thing or two, but the interface is beautiful, the graphics are stunning, and the information is gripping. Based on the hardcover book of the same name, The Elements starts with the periodic table and expands from there. Touch an element to get a cool, 360-degree view of some substance composed of it. Scroll to find some great trivia, engaging stories, and even access to up-to-the-minute information from the Wolfram Alpha computational knowledge database. You don’t need to be a chemistry major to get lost in this app for hours.
