There are a variety of chronographs on the market designed for shooters.  Some are more accurate than others, but all of them seem to have clunky interfaces that use archaic technologies like RS232 ports.  The new Caldwell Ballistic Precision Chronograph may not be the perfect chronograph, but might offer some advantages over existing units.

The unit can connect to a device running iOS such as the iPhone and iPad via an included audio cable.  Shot data is displayed on your iPhone, and the free app allows you to save data on the phone, export it via e-mail or both.  Since the interface does not use a proprietary Apple cable, I would expect that an Android app could be developed for the unit as well.

Caldwell claims the chronograph is more accurate than competitors due to a circuit with a relatively fast processor, advanced data interface and the ability to calibrate it after the unit is assembled.

Standard data is measured and calculated including velocity, average velocity of shot strings, standard deviation and spread.  Also recorded are environmental conditions.

Caldwell will offer the unit as a stand alone unit that includes a carry bag and sun screens.  Additionally, a premium kit will include a tripod and light kit.  The light kit is mandatory if you plan on using it on an indoor range.  No MSRP has been announced, and the units should ship in 2014.
