iHealth has launched Wave, a swimming tracker that aims to help improve performance in the pool.
The wrist-based device is designed to work in and out of the pool, and will count daily steps, activity and active time.

However, it's in the pool that Wave really comes into its own. It's capable of recording stroke type, number of strokes and calories burned, and displays the information in iHealth's MyVitals 3.0 app, before offering a full report on your session.
It's a very complete set of swimming metrics, which actually puts it in a small niche of devices, which includes the Misfit Speedo Shine which was released last month and the Garmin Swim.
iHealth is also releasing a connected blood pressure monitor, which records information in the MyVitals 3.0 app. It's designed to work with or without a smartphone.
