One of the fundamental differences between Android and every other mobile operating system is the practically unrestricted capability to run services. Without this freedom we could not enjoy something as powerful as a homescreen widget or as straight-forward as a Twitter client with background updates. Aside from games and very simple utilities, it’s becoming increasingly rare to find an app that doesn’t run a service, at least for a short span of time.
There are a lot of apps like SwipePad, and no matter how many we cover, I keep coming back to the original. Loopr is the first app in a while that's tempted me away, thanks to both an impressive visual presentation and some thoughtful features. At its heart Loopr is a a quick app launcher/switcher with the usual side-swiping mechanism, this time launched as a semicircle of icons similar to Circle Launcher Widget.
The virtual looping feature enables scrolling past the leftmost or rightmost homescreens with a quick bounce-to-the-opposite-end effect. While Fede implemented it this way instead of an endless scroll for technical reasons, I think it's visually a lot better and clearer, as you will still know when you've reached the end and won't feel lost in your own homescreen forest.
