One day after releasing iOS 12.1.1 and other software, Apple has finally released watchOS 5.1.2 and it is now available for download. The biggest highlight of this particular release is that it brings the highly anticipated ECG app to the Apple Watch Series 4. With this app Series 4 users will be able to take electrocardiogram or ECG using their Apple Watch. Apple Watch Series 4 is the first and only Watch that has this potentially life saving feature.
The ECG app and feature is currently available in US only, and no you cannot enable the feature by changing your region to US from Settings. Both iPhone and Apple Watch need to have been purchased from the US in order for this feature to work.
Users can take ECG readings by launching the dedicated ECG app on their Apple Watch. While you are wearing your Watch, launch the app and place your finger over the Digital Crown. Once you have placed your finger a 30 second timer will appear on your screen, keep your finger on the Digital Crown until the time runs out. You can also add a ECG complication to various Watch faces.
Speaking of watch faces, watchOS 5.1.2 also brings new complications for different apps including Mail, Phone, Maps, Home, Find My Friends, News, Messages and Remote. Users also get a brand new toggle option for the Walkie-Talkie app, which allows users to set availability for the Watch.
With this update users of Apple Watch Series 1 or later will get irregular heart rate rhythm alerts in the US. This update also enhances how rewards and tickets work in the Wallet app.
You can download watchOS 5.1.2 from iPhone’s Watch app.
