We explore the functionalities of the duo, design, sensors and more – providing a comprehensive overview for potential buyers. Let’s jump right in.
The Fit3 elevates the user experience with its more premium build and much larger display. It also packs advanced health tracking features, like the blood oxygen sensor and barometric altimeter. These are coupled with features such as emergency and SOS alerts. All of this makes the Fit3 a compelling upgrade from the original. The Fit2, on the other hand, remains a solid choice for those on a budget. It provides fundamental activity tracking in a more compact form.
Samsung Galaxy Fit3 vs Fit2: Hardware
Look & feel
In the look and feel department, the Fit3 and Fit2 offer distinct experiences while maintaining a consistent design language characteristic of the Galaxy Fit series. Both devices feature a sleek, rectangular shape, but they differ in their build and size.
The Fit3, with its aluminum case, exudes a more premium feel and is slightly larger, measuring 42.9 x 28.8 x 9.9mm. In contrast, the Fit2 is built with a polycarbonate case and is a bit more compact. It sizes up at 46.6 x 18.6 x 11.3mm. These differences in materials and dimensions contribute to the unique tactile and visual appeal of each model.
Whichever of the two you choose it will be lightweight. The new edition comes in at 18.5 grams (without the strap), while its predecessor comes in at a mere 11.3 grams!
When it comes to physical buttons, the Fit3 opts for a flat home button on the side, which aligns with its minimalist design philosophy. The Fit2, on the other hand, features a touch key below the display, offering a different interaction style that is more integrated.
Display, colour options, water resistance
The screen is another area where the two models diverge. The Fit3 boasts a larger 1.6-inch AMOLED with a resolution of 256 x 402 pixels, providing a more expansive and clearer viewing experience. The Fit2, while still featuring an AMOLED screen, is smaller at 1.1 inches and offers a resolution of 126 x 294 pixels. This difference in screen size and resolution means that the Fit3 offers a more immersive experience, particularly beneficial for reading notifications and tracking fitness metrics.
Another area of improvement its the light sensor on Fit3 which adjusts display brightness automatically. To remind, Fit2 does not have automatic brightness control. To take advantage of the snazzy new screen, Samsung has also upped the number of watch faces from 70 on Fit2 to over 100.
Both models are designed with durability in mind, featuring a water resistance rating of 5 ATM and IP68. This makes them both capable of withstanding exposure to water during activities like swimming, as well as providing protection from dust.
As you’d expect color options for the devices allow for personalization. The Fit3 is available in Prism Crush White, Pink, and Dark Gray. The Fit2, meanwhile, comes in Black and Scarlet, catering to those who prefer classic or bold color schemes. All of these options can be paired with different coloured straps thanks to the easy replacement mechanism.
Under the hood the devices are equipped with an array of sensors including an accelerometer, gyroscope and heart rate monitor for tracking various health and fitness metrics. However, the Galaxy Fit3 takes a slight edge with the addition of a barometer, the ability to take blood oxygen readings and the above mentioned ambient light sensor.
When it comes to GPS connectivity, both the Galaxy Fit3 and Fit2 rely on connected GPS, meaning they require a paired smartphone to access GPS data. So no upgrade here. This approach is common in fitness trackers to conserve the device’s battery life and reduce size and cost. Neither of the devices includes NFC capabilities, which limits functions like contactless payments, a feature more commonly found in higher-end smartwatches.
Memory-wise, the Galaxy Fit3 shows a significant upgrade. It comes with 16MB of memory and 256MB of storage, a substantial increase from the 2MB of memory and 32MB of storage in the Galaxy Fit2. This enhancement in memory and storage capacity in the Galaxy Fit3 allows for more complex software capabilities and smoother overall performance. Unfortunately none of this can be used to store music directly on the devices.
The battery life of the Samsung Galaxy Fit3 and Galaxy Fit2 showcases a notable aspect of their performance and user experience. The Galaxy Fit3 is equipped with a 208 mAh Li-po battery, offering up to 13 days of usage on a typical charge. This endurance is impressive, considering its advanced features and larger display. Samsung says the device supports fast charging, reaching 65% battery in just 30 minutes.
In contrast, the Galaxy Fit2, has a smaller 159 mAh Li-po battery. But it surpasses its successor in longevity due to its smaller display. The fitness band delivers up to 15 days of usage under typical conditions and extending up to 21 days with low usage.

Samsung Galaxy Fit3 vs Fit2: Features
The Fit3 marks a significant step up in health monitoring capabilities. It introduces a barometric altimeter, a feature absent in the Fit2, which allows users to track floors climbed – a valuable metric for those who include stair climbing in their fitness routines. Additionally, the Fit3 is equipped with a blood oxygen sensor, providing critical insights into respiratory health, a feature that the Fit2 lacks. This sensor, combined with the heart rate monitor, enhances the Fit3’s ability to offer comprehensive health monitoring.
Sleep tracking is another area where the Fit3 has an advantage. It offers detailed insights into sleep patterns, including sleep stages, snoring detection, and blood oxygen levels during sleep. The new deice also tracks naps and provides sleep coaching based on the gathered data. In contrast, the Fit2’s sleep tracking is more basic.
Additionally, the number of sports tracked has been upped from 90 to 100. The new device also adds pool swim to the handful of sports it can recognise automatically.
In terms of emergency features, the Fit3 stands out with its fall detection capability. If a fall is detected, the device can automatically ask the wearer if they need help. Additionally, pressing the Home button five times triggers an SOS message, notifying emergency contacts and displaying pre-registered medical information on the lock screen. This feature is particularly beneficial for elderly users or those with medical conditions, offering peace of mind and added safety.
Moving to smartwatch-type features, both the Fit3 and Fit2 offer a range of functionalities that extend beyond fitness. Running on FreeRTOS, they allow users to receive notifications, control music playback, and check incoming calls and texts directly from the wrist. However, neither device supports cellular connectivity, which means they cannot independently make calls or send messages without a connected smartphone. They also cannot make contactless payments or store music.
Samsung Galaxy Fit3 vs Fit2: Price
Fit2 retails for around $60 which positions it as an affordable option in the fitness tracker market. The Fit3, with its enhanced features and capabilities, retails slightly above that price point. In the countries that it is available, it retails somewhere around $70.
Samsung Galaxy Fit3 vs Fit2: Final thoughts
The Fit3, with its sleek aluminum build and larger display, offers a more premium look than its predecessor. Its advanced health features, like the blood oxygen sensor and barometric altimeter, set it apart, making it a compelling choice for users who are keen on detailed health monitoring. Plus there is the fall detection ability and SOS messages. The Fit2, while more basic in its health tracking capabilities, maintains a compact and practical design with its polycarbonate build. It should appeal to users who prioritize simplicity and ease of use.
The decision to upgrade to the Fit3 hinges on whether these new features make a difference to you. For those who value a more robust health tracking system and a refined design, the Fit3 is an investment worth considering. However, for users whose primary focus is basic fitness tracking and who prefer a more straightforward, lightweight device, the Fit2 is still a reliable option.
