A selection of 13 new apps today:

Google Drive

Google's long-rumoured cloud storage service has finally been unveiled, complete with an Android app to access photos, documents, videos and other files stored on Google Drive, while also uploading from the device. An iOS version will follow in the future, according to Google.
Android

Kinect Star Wars for iPad

Microsoft has ported its Windows Phone social app to iPad, serving up Facebook and Twitter updates with a Star Wars skin. As on Windows Phone, they can be viewed in the style of the famous opening title sequence. But no, this isn't a game.

Android

Naked Wines

UK-based online wine retailer Naked Wines has launched an iPhone app, with videos, tasting notes, shareable deals and the ability to chat to the actual winemakers: so a social app around wine, rather than a pure e-commerce app.

Lil' Kingdom

Another (for now) Android-only game, as Google's platform continues to gather pace for gaming. This is Glu Mobile's latest freemium game, which gets players to build their own dungeon. The screenshots make it look like an underground Tiny Tower.
Android

Bandsintown Concerts

Live music site Bandsintown has stolen a march on rival Songkick by being first onto Android. Its app scans the music stored on the phone, logs into Facebook, and provides a "personalised concert cloud" of upcoming gigs that you might like.

Wordament

Indie Windows Phone word game Wordament has been revamped as an Xbox Live title by Microsoft, offering boards of letters for a competitive wordsearch game against "the whole internet".
