'Seal' swim analyzer measures your stroke form and power
Samsung and Speedo aren't the only companies targeting swimmers with new products at IFA 2017. In addition the mobile giant's Gear Fit 2 Pro and Gear Sport earlier this week, Platysens, a startup based out of Hong Kong, is doing something different with its Seal swim analyzers. Still at the prototype stage, these wearable rings help swimmers measure their hands' movement and force as they push through the water, letting them use that data through a companion app to learn more about things like their stroke distribution. They can check whether their left hand is weaker than the right one, for example.
