Here at Fueled, a design and development company based in New York and London, we are obsessed with everything that happens in mobile, be it rumors of iPhone hardware, delectable Android updates or new apps we love.

Every Friday, we’d like to help you “top up” your weekly knowledge of the mobile industry so you can keep your finger on the pulse.

What'sApp!?

On Wednesday, Facebook announced that it is buying the popular messaging app, WhatsApp for $12 billion in stock and $4 billion in cash. The app, which is basically a text-messaging replacement, has 450 million monthly active users worldwide. Another notch in the Facebook belt. via Business Insider

Android Snub

Samsung is gearing up to debut a new Galaxy Gear smartwatch next week alongside the new Galaxy S5. Samsung will be using its own Linux-based operating system, Tizen instead of Android, the OS used in the original Galaxy Gear. By switching to Tizen, Samsung will have more control over the Galaxy Gear software. via VentureBeat

Candy Crushing

The brain numbingly addictive app, Candy Crush, made its pitch to investors for its initial public offering this week. The U.S. Securities and Exchange Commission filing revealed how successful the game is: the phone has been downloaded on 500 million devices, about 124 million play every day. via Bloomberg 

Nothing from Microsoft

The Mobile World Congress in Barcelona is drawing neigh, and Microsoft doesn't appear to have an offering to bring to the international event. The company is rumored to have no new software or hardware for the Windows Phone. The event will likely see the debut of dozens of new Android phones. via Re/Code

Glassholes

This week, Google posted a list of the do's and don'ts of wearing Google Glass. Google's biggest challenge with the new technology isn't the platform itself, but convincing the pubic to accept Glass wearers into society. Don'ts include: "Rock Glass while doing high-impact sports" or stand in a corner and silently film people. via TechCrunch
