The best Android apps of the week are helping you streamline your device. We're brining you a chat client and extra storage, as well as a photo viewer, a cool way to check the weather, and a different way to look at a museum.

LilyPad HD: This is an instant message client that allows you to multitask. You can chat with your friends in floating windows displayed on top of any other app. Still in beta, for now it only works with Google Talk. $1.49

Scalado Album: This alternative photo viewer just hit Android for the first time. It quickly organizes pictures into different views. For example, you can look at all the snapshots from a specific date or location. $0.99

Google Drive: This week Google launched Google Drive, its long-awaited Dropbox competitor, and along with it came an Android app. It lets you create, save, sync, and share your files from anywhere. If you're a heavy Google Docs user, you'll definitely want to add this app to your repertoire. Free

James May's Science Stories: Using augmented reality, this app gives you a peep into the London Museum of Science with TV personality James May. You can educate yourself on things like the Model T and the first x-ray machine, and afterwards you can take a quiz to see how much you've learned. $3.20

Weatherwise: It's hard to make weather interesting. But this app puts the usual data into a pretty package, with handsome skins and animation. It also gets more detailed than your average forecast apps, with 20 different conditions detailing things like sunsets and the strength of thunderstorms. Free
