Seems the iPhone’s become a superb diagnostic tool through sound analysis — not only can it evaluate watermelon ripeness, but now it can also be used to measure the tension of tennis or squash racquet strings with the racquetTune app.
The $1 app sports a slick, clean interface that displays a string’s tension after a few taps; there’s also a swingweight calculator thrown in for good measure.
The Swedish developers say racquetTune has been tested at the Royal Institute of Technology in Stockholm to good result — who knows, perhaps even by Bjorn Borg himself.

Since then, his fascination with technology has made him an intrepid early adopter of whatever charming new contraption crosses his path. He calls San Francisco home, where he works as a journalist and photographer. Eli has contributed to the pages of Wired.com and BIKE Magazine, among others. Hang with him on Twitter.
