I am happy to announce that ECG and Blood pressure monitor are finally officially available in 31 countries, including EU states, the UK, and also the UAE. You will need to download just one app, Samsung Health Monitor, and the app will be available in Samsung Galaxy Store starting on Feb 4.
@arunmukundan you can still install those apps unofficially and it is working just fine. I have been using them for 3 months now. I can provide you with the apps if you want ;)
here are apks you need to download and install. After installing them the Samsung Health Monitor app should appear. Click on it and then follow the steps.
