iPhone Apps

Bill Nye the Science Guy turns 20 this year (as in the show, not the guy — he's 57), and to mark two decades of demystifying the sciences, the official Bill Nye the Science Guy (free) app has just been released in celebration.

Like the host himself, the app is quirky, zany, and full of fascinating science facts. Poke around Bill's desk to discover a MarsDial that reads time on the Red Planet, small Science Guy trinkets (bow tie mandatory), and eye-boggling optical illusions.

The app also features two games and a small archive of clips from the show's best episodes. The Planets and Magnetism demo some of our favorite experiments. Speaking of science investigations, the Science Guy app also has a built-in catalog of at-home experiments that can help explain concepts like static electricity and atmospheric pressure (great for kiddos!)

Download Bill Nye for mobile, give the app a try, and celebrate the Science Guy's 20th anniversary all year long by sending us your favorite moments from the show in the comments.

If you're addicted to Cartoon Network's hit coming-of-age show, relive the postapocalyptic exploits of Adventure Time with Finn-launching, rock-smashing, Fionna-fighting apps.

The adventures of a hat-wearing boy hero and his talking dog continue on mobile, with iOS and Android games that bring all the goodness of Ooo to phones and tablets.

• Rock Bandits ($2) — In this iOS game, rescue Marceline's stolen fans by slashing and smashing bad guys with Finn's sword. Earn new blades and conquer 20 levels. The app also comes with a free original comic by the series' writer!

• Fionna Fights ($1) — The iOS app features the one and only Fionna, who battles evil monsters with a magical crystal sword. Cake and Marshall Lee will, of course, never leave your side as the fierce, furious Fionna.
• Jumping Finn Turbo ($1) for iOS and Android — Fight penguins, ride Lady Rainicorn, and do whatever else duty asks of you to save Princess Bubblegum. Send Finn deep into Ooo with the help of Jake, who will kick his human companion's boo-tay high into the atmosphere.

Have you not been bit by the Adventure Time bug yet? Give the hilarious, fantastical series by Pendleton Ward a try — even top critics herald the show as a highly intellectual animated series that's not just for kids!

IPhone users have been begging for the ability to take their Excel, PowerPoint, and Word documents on the go since, well, the iPhone was created in 2007. Today, productivity dreams came true as Microsoft announced Office 365 for iPhone users. Available for download from the App Store on Friday, Office 365 Home Premium and ProPlus subscribers can use the app to view, edit, and comment on documents for no extra charge.

The iPhone app makes use of the cloud-based Office 365, available for $100 per year to be used across five devices like your work and home computers, or any other mobile devices. Using SkyDrive, the app syncs Word, Excel, and PowerPoint documents to wherever you left off when previously logged in to Office 365. Documents are organized in the most recently opened panel, and can be identified by type with icons for Excel, Word, or PowerPoint.

It's been almost nine months since Myspace, the reigning social network of the early '00s, previewed its design transformation. Now the Justin Timberlake-approved (he's a co-owner) "social entertainment destination" has come out of beta, debuting a new landing page and an iOS app.

We put the Myspace app under a mobile microscope to figure out how much the platform founded by everyone's first social network friend, Tom Anderson, has changed.

Myspace has reformatted itself to cater to the creative community (artists, writers, photographers, and the like), but there is a clear emphasis on musicians. Myspace Music had always been the company's stronghold, and the music-centric features of the desktop site, like user-created playlists and musician profiles, have spilled over into Myspace for iOS.

Internet radio apps like Pandora, iHeartRadio, and Slacker are a dime a dozen, but the Myspace mobile app distinguishes itself with well-curated, high-quality radio stations (not to mention unlimited listening). Before downloading the new Myspace, take a look at some of the platform's new features.

Genre- or User-Based Radio

Myspace for iOS is actually a mobile music-streaming service hiding under the cover of a social network app. Radio is the app's best feature: the selection of music is varied, listening is unlimited, and there's a wide array of genres and musician-based radio to choose from.

The caveat is that you can only skip a track four times, but you can switch between stations unlimited times. Our favorite radio station so far? Pharrell's.

Inspiration can strike when you least expect it, which is why Adobe Kuler (free) is a must for your app arsenal. The newly released iOS app automatically creates color themes based on photos from your camera roll, Flickr, or the web.

In camera mode, Kuler extracts the dominant hues in an image, and animated little circles move around, revealing the most eye-popping colors of that picture. Tap the image to stop the animation, then drag the circles around the screen to target specific colors in a photo. Adjust the colors with a color wheel or RGB sliders and, once your theme is set, share it via Twitter or email. Kuler will also display colors' monochromatic and complementary colors to help you round out your theme.

All of the themes you've worked with are synced with the Adobe Creative Cloud and saved in the app so that you can refer to them whenever you need. If your Adobe Creative Suite Software (InDesign, Photoshop, etc.) is synced to your Creative Cloud account, then the color themes will show up automatically in your work spaces, too.

Give Kuler for iOS and the corresponding web app at kuler.adobe.com a try and let us know which hues are on your mind!

Tired of blackened kernels instead of your crispy snack? There's an app for that. We're happy to present this post from our friends at Yahoo! Shine.

Ever since microwave popcorn became popular in the early 1980s, fans of the whole-grain snack have faced a familiar problem: if you don't stop the microwave at exactly the right moment, you end up with either too many tooth-shattering unpopped kernels or a bag of scorched popcorn and a smoke-filled kitchen.
