Stopwatch, countdown Android App

The description of Stopwatch, countdown: I d like to introduce to you a new application for mobile devices: a stopwatch that works both as a stopwatch and a countdown counter. Also it s possible to start this app with these both modes on and minimize it (the counting will continue). This application is not overloaded with redundant stuff so it has all relevant functions. You can use it to: measure the amount of time elapsed from a particular time when activated to when the piece is deactivated count down to a particular event (when the set period expires the timer indicates so)time for countdown counter can be set both in milliseconds and in hh mm ss form. I d also ask you to comment my program and inform me of some errors or write me if some upgrade is needed. Together we can make it better! ..
