Meet the iFit Duo: a smartwatch with an analog watch face on the front and a digital tracker on the back. You can just reverse it to start tracking fitness activity. The device can track calories in/out, sleep, steps, and distance. It has a 3-axis accelerometer that automatically detects activity type (walking, running, cycling, and swimming).
Just like other smartwatches, the iFit Duo supports smartphone notifications. It is Bluetooth heart rate compatible. The device will be available Summer 2015.
