USING phone for pseudo Fat timing?

If a partner holds a phone is their an app and an associated piece of hard ware I can buy that will trigger once I cross a line and finish once I cross another line? I Know the professional systems are thousands, but is their any thing for £100 to do such, like say you place a beam thing on the finish line of your course and the start line of a track, you program it to either stop timming after the first time the chip cuts through both lines (400m) or the second time (800m) etc.  No button presses at all (except in programming before starting to adopt position to time) would be desirable to get as accurate as possible without buying pro stuff.
