The Samsung Galaxy Fit3 is a smart fitness tracker that offers a range of features for health and activity monitoring. Users appreciate its lightweight and comfortable design, making it pleasant to wear. The device provides interesting measurements such as sleep tracking, calorie burning, and heart rate monitoring. However, some users have experienced issues with synchronization and find the software interface somewhat inconvenient, particularly in terms of water consumption tracking and measurement settings. The battery life has been a concern for some, with reports of it draining faster than expected. Despite these issues, the screen quality and overall functionality are generally well-received, with the device offering a variety of sports modes and notifications. The magnetic charging and vibrant AMOLED display are additional highlights, although some users feel the bezels are too large. Overall, the Samsung Galaxy Fit3 is a capable fitness tracker with room for improvement in software and battery performance.

Great value for money fitness band.
12 July 2026 
Nice bracelet
High-quality materials, a strap that's soft to the touch, a vibrant screen with auto-brightness and gesture activation (good accelerometer), aluminum frame, quality and functional interface, smooth 60Hz, ability to finely adjust vibration
Not as flexible customization as I would like
Bobrokuse Samsung Galaxy Fit3 few months
A lightweight watch with a basic set, without GPS - for undemanding users.
25 December 2025 
Bought to see if it's worth investing in a more expensive watch and to check approximate data, and get used to a digital watch (tracker). I have a Samsung smartphone, so connecting and syncing was seamless with no issues in operation. I've shown in the picture that the player works fine too. Just turned on the radio on the smartphone, and immediately the information is visible on the tracker, the volume can be adjusted, and switching to the next station is hassle-free.

There aren't many watch faces, but something can be chosen. With poor vision, I chose one with minimum information but large numbers, so I can tell the time without glasses.

I measured the strap with a ruler — it can fit a wrist up to 21 cm in circumference.

To avoid it shining in my eyes at night, I disabled the feature where the watch face lights up when you raise your hand, so it only activates with a touch on the screen or a button press.
I shower without taking it off; the screen is nice, I chose a large display so I can see it without glasses when I'm half-asleep. It can be worn on either the right or left wrist. When setting it up, you need to specify the wrist and which side the button will be on.
The pedometer works even when you just wave your hand while sitting in a chair. The sleep phases are not shown very accurately, as you can see from the screenshot. If you lie in the evening and calmly watch TV, it might later indicate you were sleeping, and sometimes at night, it also shows you're asleep when you're not. The sensors that glow green and red at night are really annoying — I don't understand why they don't make them without such lighting. (Yes, they're quite visible at night). Since there's no GPS, you have to use an app on your smartphone to turn on and sync, which is not very convenient.
Mykola Mazurykuse Samsung Galaxy Fit3 few months
Great basic fitness bracelet for the price-quality ratio.
24 December 2025 
For its price, this smart bracelet is quite good, especially if you use a Samsung smartphone. Basic functions like notifications, pedometer, media control, and flashlight work well.
Good battery life, light weight, not felt in the hand, bright and rich display.
A few times, the call notification didn't arrive, and only later, the missed call notification appeared. A few times, the flashlight turned off at an inconvenient moment. There's a small number of watch faces and the inability to install custom ones.

Popular questions about Samsung Galaxy Fit3

Verified 21 august 2026, Serhii Shkurupii

Can I swim with the Samsung Galaxy Fit3?

Yes, the specifications indicate 5 ATM water resistance and that the Galaxy Fit3 is suitable for swimming. During testing in a pool, the band recorded time, distance, pace, average heart rate, calories, swimming stroke type, stroke count, and SWOLF. This data is suitable for basic workout tracking; however, the statistics provided are less detailed than those offered by specialized sports watches.Source:SpecificationsExpert reviews

Can I record a running route without a phone?

No, Samsung Galaxy Fit3 does not plot a route independently because it does not have built-in GPS. It will show basic workout metrics, but the distance without a smartphone connection will be estimated and may differ from the actual distance. This is sufficient for walks and general activity, but not always for running along a route.

What can’t they do compared to full-fledged smartwatches?

The Samsung Galaxy Fit3 does not have NFC for payments, built-in GPS, or support for installing third-party apps. It is a fitness band for notifications, music control, and basic activity tracking, and it cannot record a running route without a smartphone.Source:Expert reviews

Is Samsung Galaxy Fit3 compatible with iPhone?

The bracelet is designed for smartphones running Android 10 or later with more than 1.5 GB of RAM. The Samsung Wearable app is used for setup and updates, while activity data is saved through Samsung Health; connection with Samsung smartphones is simplified thanks to automatic detection. Galaxy Fit3 support on iPhone was unavailable at the time of the described connection, so iOS owners should not expect compatibility without separate confirmation.

Is the Galaxy Fit3 comfortable to wear all day and while sleeping?

Galaxy Fit3 is designed for extended wear: the body without the strap weighs 19 g, while the device with the strap weighs 36.8 g in the review described. Users repeatedly note its light weight and comfort, as well as the fact that the band is barely noticeable on the wrist; the 1.6-inch AMOLED screen remains large enough for reading information. However, the proprietary attachment limits the choice of compatible straps, and one user found the included strap too short and inconveniently shaped.Source:Expert reviewsGeneral information

How long does the Samsung Galaxy Fit3 last on a single charge with normal and active use?

The claimed battery life is up to 13 days, but with active features enabled it may be noticeably shorter. In the described experience, the band lasted about 6 days with the always-on display, active measurements, and a daily 30-minute workout, and up to 10 days without the always-on display, depending on usage. Some users report the battery draining within 2–4 days, so actual battery life depends heavily on the settings, monitoring intensity, and condition of the specific device.Source:Expert reviewsGeneral information

How reliable are the heart rate, step, and sleep measurements on the Galaxy Fit3?

The measurements are better suited to general monitoring than demanding sports analysis. When comparing heart rate with sports watches, the readings matched at rest, while they differed more significantly during running; at the same time, the accuracy of the optical sensor may depend on tattoos, moles, and hair on the wrist. Several users report erroneously added steps, incorrect sleep detection, or missed measurements, so critically important metrics should preferably be checked using another method.
