You might be thinking, “What the ….”
Yes, I am dam serious! So, the question that I want to answer here is,
Is Samsung Galaxy Watch 3 Compatible with iPhone?
We have already reviewed the Galaxy Watch 3 and watch 4, and it comes with a lot of features like FDA Approved ECG, fall detection, cutting edge design, and it is a great alternative to Apple Watch 6.
Samsung Galaxy Watch 3 is one of the most advanced smartwatches in 2021. It is packed with a lot of health and fitness tracking features.
- Combines powerful technology and premium design to track your day-to-day activities
- Comes with advanced health monitoring features like ECG, SpO2, B.P, Heart Rate and much more
- LTE model allows you receive phone, SMS, etc even when you leave phone at home
- Water Resistance of up to 50 meters
The Galaxy Watch 3 and Galaxy Watch 4 are compatible with both iPhone and Android devices. More specifically, the Galaxy Watch 3 is compatible with Android devices running on Android 5.0 or higher and RAM 1.5GB above.
Similarly, it is compatible with iPhone running on iPhone 9.0 and iPhone model 5 and above.
You can have a complete list of Android smartphones compatible with Galaxy Watch 3 here.
Being said this, the answer to the above question is not a complete “Yes.” Instead, I would say a partial “Yes” and a partial “No.”
I will tell you why!
You cannot fully explore the features of your Galaxy Watch 3 or Galaxy Watch 4 if you are using it along with an iPhone; this is the same for other Galaxy Watches such as Galaxy Watch and Galaxy Watch Active 2.
Now let us have a look into the features that are restricted for iPhone users,
1. Watch will be a bit slower
When you use Galaxy Watch 3 with iPhone, you may feel slightly laggy, especially during data loading and app download. If the watch lags more, you can try to fix the issue by unpairing and pairing it again.
2. Message Replay Not Available
Replay to message function is not available with Apple devices. For example, you cannot reply to SMS, WhatsApp, email, etc.
3. Samsung Health Features
Some health tracking features do not work when you use them with an Apple watch.
4. Emergency SOS
Samsung Galaxy Watch 3 starts to ring an alarm if the user falls suddenly. If the user does not deactivate the alarm immediately, the Galaxy Watch automatically sends SOS alerts to the emergency number with real-time location.
But this fall detection alert does not work while you use it with an iPhone.
5. A Few Samsung Apps Not Available
Some Samsung only features and apps do not work with the iPhone. Samsung Pay, T-money, and Nike Running are few apps to name.
Besides, it only allows you to download some free apps and some other watch-specific apps only. But compatibility and availability of apps further vary by the developer, OS, etc.
So, the final answer is;
If you are an Apple Phone user, then I recommend you go for an Apple Watch only. Because, even if you spend more than $400 to buy the Galaxy Watch 3, you won’t be able to explore it completely.
So, it is always better to go for the Apple Watch Series 6 or 5 if you have the money to spend on Galaxy Watch 3.
Features of Apple Watch Series 6

- GPS
- Always-On Retina display
- Swim proof
- ECG app
- Electrical and optical heart sensors
- Built-in compass
- Emergency SOS and Fall detection
