Differences:
1. Digital bezel on the Active2 vs Physical bezel on Watch3 (makes a big difference for some)
2. Watch3 is Stainless steel vs Aluminum for the Active2
3. More RAM (1 gb vs 768mb) on Watch3
4. Active2 is more sports (look) oriented vs Watch3
Similarities:
1. Same OS version, Active2 was recently updated to the latest Tizen 5.5 bringing ECG
2. Same screen size
3. Same processor
Basic idea is to create your own certificate to sign ECG.tpk application and install it on your watch, then install the Samsung Health Monitor Mod app on your phone.
I have read lots of threads on XDA and can't find a complete tutorial about how to do it for Galaxy Watch 3 or Active 2. Hope this step-by-step tutorial will help. The whole process took me around 30 mins, it shouldn't be very hard. Make sure you back-up your watch first, just in case anything goes wrong and you need to restore data.
You will need an Android Phone, a Windows PC, and Galaxy Watch 3/Active 2 watch for this tutorial. And a wireless network.

Reboot the watch. Make sure wifi is connected after the reboot.
From Your PC:
Launch Tizen Package Manager and Navigate to 5.5 wearable(It depends on your watch's software version, eg mine shows Tizen Version 5.5.0.1, so I navigate to 5.5 wearable), then click Install icon
Scroll down to the Tizen SDK tool and click the install icon
Click on the Extension SDK tab
Click the arrow on Extras
Install Samsung Certificate Extension and Samsung Wearable Extension
Check the Progress tab, once it shows 100%, you can close Tizen Package Manger and do not launch Tizen Studio(we don't need to use Tizen Studio)

A pop up will ask you to sign in to your Samsung account, enter your account information and sign in
Now it will show your certificate has been saved at C:/Users/USERNAME/SamsungCertificate/cert_name and click next.
Create a new distributor certificate and click next
Do not change Privilege and password information, do not close these windows, just leave it there, we need to enable debug mode from the watch and connect it to the PC now.
Open "Device Manager" from the PC.
Click the "Remote Device Manager" icon from the top right corner.
From pop-up windows, click the "Scan Devices" icon from the top right corner.
Once it finds your watch turn the connection switch to on. and close pop-up windows. At this time, you should able to see lots of debugging information from the Device Manager.
Go back to Tizen Certificate Manager, step 9.8, we can see one DUID has been added automatically. Click next.
It will show your certificate has been saved at C:/Users/USERNAME/SamsungCertificate/cert_name, Click Finish.
Download Fit2installer.zip unzip the whole folder to your desktop.
Go to the certificate(C:/Users/USERNAME/SamsungCertificate/cert_name) you just created and copy all files. inside the folder
Go to C:\Users\USERNAME\Desktop\Fit2Installer\cert Paste all the certificate file you just copied.
Copy ecg.tpk file and paste it at C:\Users\USERNAME\Desktop\Fit2Installer\sign_me
Click sign.bat from the Fit2Installer folder. Enter your certificate password.

Now go to "Device Manager", right-click your device, choose "install app", Select ecg.tpk file from C:\Users\USERNAME\Desktop\Fit2Installer\install_me.
Wait a few seconds, you should see ECG app has been installed on your watch. Open it.
Open the "Samsung Health Monitor" app from your phone, you should be able to read the ECG data from your watch now.
As Blood Pressure has not been released in the U.S, once it released, you should be able to activate for Non-Samsung phone the same way. You can disable debug mode if you want now.
Enjoy!
