Withings' fitness watches automatically track your swimming
Most activity trackers and smartwatches won't monitor your swimming, and those that do usually require that you kick in a swimming mode before you dive in. Withings doesn't think you should have to switch things up just because you've left dry land, though. The health tech firm has added automatic swim detection to its Activité and Activité Pop watches, so you only need to start that breast stroke for it to register as a workout. You probably won't want to take your tracker on a deep scuba dive (both wearables are resistant down to 164 feet), but this could be very helpful if you'd rather hit the beach this summer than roast during a run.
