Weather App. The Watch will have a weather app. There’s not much to say other than you can check the weather at a glance. The unique part of this app is the layout. Most weather apps are designed based on a scrolling list of days or hours. The Watch weather app UI is based on a clock. At each hour position lays an icon that depicts the weather for that hour of the day.
Remote App. The Watch will have a apple TV remote app built right in. This means that you can control your Apple TV via your watch. You can swipe around the UI or you can scroll through lists right from your wrist.
Two words, Pay (ok 1 word and 1 logo)! Yes the Watch will include Pay built right in. Instead of having to pull out your iPhone to make a mobil payment, you now can just double press the side button on the watch and move your wrist towards the cash register and you are done! How apple thought about security for this is genius! In the morning when you first put on Watch you will be asked to put in a security code. This will allow Pay to be active. The question you are asking is what if someone steals my watch. Well the solution is very simple, your heartbeat! As soon as you put Watch on it begins to measure your pulse rate. If you takeoff the watch it will know that you did so and it will inmeditly turn off Pay. The best part of this is that you don’t need to have an iPhone 6 or 6 plus which includes the Secure Eclave to protect your finical data and the NFC chip to transfer the transaction. Both parts that make up Pay on the newer iPhones are built right into Watch. This means that people that own and iPhone 5C, iPhone 5 and iPhone 5S will immediately have the capability to pay for things with Pay.
Watch has a maps app. The cool part of this app is that it will tie directly to the Taptic Engine(custom vibrator motor that feels like someone is taping you on the wrist). This means that if you get walking directions to somewhere, instead of the watch speaking out directions to you to turn left or right, It will instead tap your wrist. There will be two distinct taps, one for turning left and one for turning right. As you walk down the street the watch will gently tap your wrist to let you know when its time to turn left or right. This is going to be awesome for the blind!
