Samsung locks Galaxy Watch features by region. It’s been doing this for years and honestly, that’s embarrassing for a company selling premium hardware at premium prices. A developer named Dante63 decided enough was enough.

If you’ve been following Galaxy Watch modding circles, Dante63 isn’t a stranger. This is the person who built a patched version of Samsung Health Monitor to crack open ECG functionality for users in unsupported regions.

Now, Dante63 has surfaced something bigger: an app called GeminiMan Wellness Companion. The headline feature right now is ECG recording directly from your Galaxy Watch, with reports and AI analysis pulled into the phone app.

You get heart rhythm, heart rate, and something Samsung doesn’t bother including: a confidence score for each reading.

Running GeminiMan and Samsung Health Monitor side by side revealed an elevated heart rate. Meanwhile, GeminiMan flagged two recordings as showing abnormal rhythm that Samsung’s app missed entirely.

The custom notes feature is the quiet killer here. GeminiMan lets you write whatever you want. For anyone managing a chronic condition, like migraines that spike heart rate, that flexibility isn’t a nice-to-have.

Multiple profiles work too. Share a watch with a partner or family member? You can pull readings for different people without contaminating your own data.

You can back everything up with encryption, and you can export ECG reports as CSV or PDF depending on which chart type you’re working with.

If you’re outside Samsung’s approved regions for health features and you’ve been watching your expensive watch collect dust on capabilities it physically has, this app is worth your attention right now.

Beyond that, Dante63 has published a full development roadmap on the GeminiMan GitHub page.

• Phase two brings blood pressure recording.
• Phase three expands into a full wellness platform pulling in blood oxygen, heart rate variability, sleep data, and skin temperature.
