Photosynth was one of the cooler apps for Windows Phones, when it finally hit Windows Phone 7.5 in spring last year. However, until today it wasn't compatible to Windows Phone 8, even if it was a Microsoft app. Also available since 2011 for iOS, Photosynth for Windows Phone is a panorama app that makes it easy and fun to capture and share interactive panoramas of places, people, and events. Using the latest in computer vision techniques, Photosynth is the acknowledged leader in mobile panorama creation. It is the only app available on Windows Phone that allows you to capture 360° horizontally and vertically, making a perfect "sphere".

It's not a secret anymore that I love bags for a long time and my most favorite bag brand today is Timbuk2; and yes, I have a personal fable for the bags from San Francisco. Somehow, a gadget user, traveler and professional has to carry all the stuff, like during this week's Mobile World Congress in Barcelona, and Timbuk2 gave me from day one what I was looking for. A fashionable, customized looking messenger bag which is different from other bags. Somehow, or better thanks to social media, Timbuk2 recognized, that I'm one of their bigger fans on the other side of the pond and they invited me last year to visit their HQ whenever I'll be in San Francisco. Thanks to Frequencies by HTC, I was in town earlier last month and therefore I took the chance to meet with the folks from Timbuk2, namely with Noel, Timbuk2's community manager.

Sure we need another digital wallet solution and that's exactly what Samsung thought as well and therefore the Koreans introduced at today's Developer Day at the Mobile World Congress its own "Samsung Wallet". If Apple's Passbook (which also works just fine on Android) or Microsoft Wallet isn't enough for you, Samsung Wallet is said to be a convenient mobile app which allows users to store and manage event tickets, boarding passes, membership cards and coupons all in one place. By using Samsung Wallet API, partners can integrate their Associate Apps and Samsung Wallet in the way that they can add their tickets and coupons to Samsung Wallet.
