Today Apple released watchOS 5.1.2. watchOS 5.1.2 contains a few bug fixes as well as some features. Some of the fixes and other changes include:
  • Enables direct access to supported movie tickets, coupons, and rewards cards in Wallet when tapped to a contactless reader
  • Receive notifications and animated celebrations when you achieve daily maximum points in a day during an Activity competition
  • New Infograph complications for Mail, Maps, Messages, Find My Friends, Home, News, Phone, Remote
  • Manage your availability for Walkie-Talkie from Control Center
Each of these updates are nice improvements. The biggest change with watchOS 5.1.2 is the inclusion of a feature that was announced at Apple’s September event. At the event Apple announced the Apple Watch Series 4, and they pre-announced the electrocardiogram, or ECG, app. The app is capable of the following:
  • Allows you to take an electrocardiogram similar to a single-lead electrocardiogram
  • Can indicate whether your heart rhythm shows signs of atrial fibrillation—a serious form of irregular heart rhythm—or sinus rhythm, which means your heart is beating in a normal pattern
  • Saves ECG waveform, classification and any noted symptoms in a PDF on the Health app on iPhone to share with your doctor
  • Adds the ability to receive an alert if an irregular heart rhythm that appears to be atrial fibrillation is detected (US and US territories only)

In order to use the ECG app, you must be running both iOS 12.1.1 and watchOS 5.1.2. This cannot be the beta version, but the release version. iOS 12.1.1 and watchOS 5.1.2 are available now.
