After a long, long development process, Blocks is getting relatively close to releasing its modular smartwatch -- and it wants your help making that final push. The startup has launched a Kickstarter campaign to fund its customizable wristwear. Pledge $195 and you'll get the circular core watch, which gives Android devices and iPhones the fundamentals like activity tracking, phone alerts and voice control. However, things get really interesting when you drop $250 or more -- you'll get at least four modules that can add everything from advanced fitness tracking to GPS to mobile payments. The hope is that you'll get just the smartwatch you want, rather than settling for whatever other manufacturers feel like giving you.
