The Liquid Leap+ by Acer is now available in the US. The wearable is not only a fitness tracker, but also adds some smartwatch capabilities. You can do things like control music, receive emails, and get text messages.
Due to less functionality compared to a full fledged smartwatch the battery last quite a while. It is estimated at 120 hours of run time or 240 hours of standby time for a single charge. It is also waterproof with IPX7 certification. It comes in three colors black, green, or pink. The price is $99, but as a launching promotion it is on sale for $79.
