One of the interesting features of the Galaxy Watch 4 is the presence of ECG and Blood pressure measurement. However, and unfortunately, too, these features are not available in every country of the world. This is most likely due to regulatory policies. Moreover, for you to access these two features, you need the Samsung Health Monitor (SHM) app. These limitations have prevented many owners from accessing these features on their Galaxy watch 4. Nevertheless, a user that goes by the name dante63 on XDAdevelopers has been able to modify the SHM app to remove these limitations. This modified SHM will allow you to install ECG and blood pressure measurements on your Galaxy Watch 4 irrespective of your location or whatever phone you’re using. This simple guide will show you how to get ECG and blood pressure on your Galaxy Watch 4.
How to Get Blood Pressure and ECG Measurements on Galaxy Watch 4
The ECG and blood pressure features on the Galaxy Watch 4 require the SHM app installed on both your phone and watch. In this regard, we’ll have to install the SHM on phone and on the Galaxy Watch 4. We’ll install that of the phone first, then follow up by installing it on the watch.
There are two apps below, the first one should be installed on your phone, while the second one should be installed on the Watch.

Install SHM app on Phone
To install the modified SHM app on your phone just click on the first link above and install it like you would on the norm. Note that since this app isn’t available on Google Play Store, you may need to grant permission to install apps from unknown sources. This can be done from the settings app on your phone. Install the app and don’t open it yet until we have installed SHM on the watch.
Install SHM app on Galaxy Watch 4
Now that you have successfully installed SHM on the watch, we need to install SHM on the watch as well for ECG and BP to work. To install SHM on watch we’ll need the Bugjeager app to help us do this. This app allows you to install apk files remotely on a device, and it’s available on Google Playstore.
- Go ahead and install the budjaeger app on your phone.
- If you have installed the Bugjeager app on your phone, go ahead and open the Settings app on the Galaxy Watch 4 and scroll down to where it says about watch, and tap to open.
- Tap on about watch and scroll down to software, and tap to open it.
- Scroll down to where it says software version and tap to open it.
- Scroll down to the software version and tap on it multiple times to enable developer mode. You should see developer mode turned on. Once done, go back to the Settings app main menu.
- From the Settings app main menu, scroll up to connections and tap to open.
- Click on Bluetooth to toggle it off, then go back to the previous menu.
- Click on WiFi and toggle it on if it is off. You can learn how to set up WiFi on the Galaxy Watch 4 if you’ve not already done that.
- Once WiFi is turned on, go back to the settings app main menu and scroll down to developer options which is right under accounts and backups. Click to open.
- Tap on Developer options, find ADB debugging, and toggle it on. Also, toggle on debug over WiFi and note down the IP address you see. This is the IP address of your WiFi network. The Bugjeager you installed earlier will need this IP address to connect to the Galaxy Watch 4. Note that the IP address takes about 10 seconds to show up or you can simply go back to developer options and return back to debug over WiFi to see the IP address.
- Open the Bugjeager app you installed earlier and tap on the plug icon with a plus sign to connect to the same WiFi the Galaxy Watch 4 is connected to. Enter the IP address we noted down earlier and click on connect. If successfully connected, you should see “no device connected “ change to another address that contains your WiFi network IP address.
- Press the center menu with an icon pointing upwards. Then tap on the plus icon at the top to select the SHM app for Watch you installed earlier. Select the apk file and tap on install to install SHM on the Galaxy Watch 4. This will take a while to install the app on the watch. If successfully installed, you should see the SHM app icon on the watch.
Now that you have successfully installed the modified SHM app on both watch and phone, you can now open the SHM app on your phone to setup ECG and blood pressure measurements on the Galaxy Watch 4. You will need a traditional blood pressure monitor to calibrate blood pressure on the watch. This will allow you to get the possible best readings.
