13．

April will bring a new product-the Apple Watch-into the market．Last week，the watch was firstly introduced by Tim Cook，Apple's CEO．The price of the watch will differ from 349to 1，099，depending on its size，strap and whether it is a sports or regular version．
Apple engineers and designers have put in a lot of thought and hard work into creating this"small screen"on your wrist（手腕）．The"sensor"on the screen not only detects your finger，but knows the difference between when you are tapping，and when you are pressing harder．
The watch also has"haptic feedback（触觉反馈）"．You can send personal messages to your friend-such as drawing a star or a special sign with your fingers，or tapping the watch，say 3times，and your friend will receive those taps on their wrist．
Besides telling the time，the watch will use'bluetooth'to connect with your iPhone and show calls or text messages that come in．
According to Tim Cook，the watch may open up a whole new area of applications that we had never thought of．Some car factories like BMW have developed an app that allows its car owners to open their cars with the watch．A'Hotels'app may allow you to open the door to your hotel room without worrying about losing the smart-card．And finally，even airlines are jumping in-passengers may be able to simply wave their wrist to check into their flight．
The biggest use of the watch，however，is as your personal fitness coach．The watch can measure your pulse （heartbeat） using a sensor at the bottom of the watch．It also has the same"accelerometer"as your iPhone，so it knows when you are moving，and also how much you are walking or running．It will remind you if you have been sitting for too long without much activity．
Many stores are planning to stop selling the Nike，Jawbone and FitBit devices（设备） to welcome the Apple Watch．Will Apple Watch really replace these devices and make fitness much more fun？
