Android: Sidebars are all the rage in apps right now, so why limit them? Appsi adds swipe-out sidebar panels that can be triggered by hot spots.
The app allows you to designate several hotspots on the side of your screen. Swipe inward from that spot and you can pull out one of several sidebars that give you quick access to information.
By default, Appsi comes with an app shortcut sidebar, although each additional plugin costs roughly $1. You can add calls, contacts, SMS, calendar events or settings for up to six different slide-out panels.
