Seal captures your hands' movement as you push through water. Our algorithm reconstructs your hands' motion, and measure the force and power exerted by each hand over time.  Pinpoint the factors that affect your swim stroke and measure the difference.  Compare against other swimmers and make your stroke more efficient.
