Spark is aimed for two kinds of people: Those who are social networking fanatics and those Android users who don't care about customization as much as they care for a simple experience. In that aspect, Spark excels.
The app brings feed from Facebook, Twitter and news to your android phone in one easy to read screen and updates them in real time. It uses a next-generation version of HipLogic's MobiJax virtual machine platform which allows it to mimic a full operating system and works in conjunction with the company's Web services to deliver content. The MobiJax platform allows for multitasking, and since it's virtualized, users can log into their HipLogic home screen across multiple devices.
HipLogic also offers an app store within Spark so users can customize their home screens even further. The app is a followup to HipLogic Live, the company's home-screen app for Nokia and Windows Mobile which has users in 185 countries and is available in eight languages.
The Spark beta is available in the Android Market today for phones using version 1.6 and up. It's free, so check it out!
