Good Device at the price point
From having been in the Samsung ecosystem with many excellent products for several years, I recently purchased the new Galaxy Fit tracker. In order to have something to compare against as relative benchmarks, I compared its performance against two other similar devices. My review will be divided into overall impressions, specific observations, and recommendations.
Overall impressions: this is a very good product at the price point. Overall it works well and is reasonably accurate, and for the price and current state of technology for wrist-based fitness trackers, is a good buy. Hopefully the few problem areas noted will be corrected in future software updates.
However, I recommend assessing your needs and then carefully comparing specifications of the devices. Also realize that there are limitations in the technology and no device will be as accurate as the corresponding medical measuring device. After using a fitness tracker, I believe the primary value is that it has raised my health awareness about my level of physical activity, a proper diet, exercise, and having an overall proactive approach to managing my health. For additional information on fitness trackers in general, there is an article, "Evaluating the Validity of Current Mainstream Wearable Devices in Fitness Tracking Under Various Physical Activities: Comparative Study," that has useful information on the topic.
- Aesthetics. The watch has a very good overall design, is lightweight, and as with all other Samsung products I've had, has an excellent, vivid, AMOLED display. The display is readily visible in all ambient lighting conditions, including outdoors.
- Notifications. Worked very well and all were received from the reference phone (Samsung Galaxy S10+) instantaneously.
- Message reply feature. This works very well and is an excellent feature.
- Distance monitoring. The distance tracking was close to readings from the GPS device used for comparison. Variance was negligible.
- Step tracking also was also reasonably accurate and consistent when compared to reference devices.
- Integration with the Samsung Health app was excellent.
AREAS NEEDING IMPROVEMENT:
- Band. The band is awkward to take on and off, as it is not a traditional watch style band.
- Heart rate monitoring results were inconsistent. At times they were similar to the benchmark devices and readings I have obtained from the doctors' office, other times they were off by 25% or more. I have read other reviews where reviewers stated their results were very accurate; variances may be to differences in positioning of the band on the wrist, skin density, etc. The accuracy was greater overall when measurements were taken at rest than during my workouts.
- Workouts. My workout regimen includes outdoor walking, indoor treadmill, and rowing machine exercises and I tried the Galaxy Fit on each and compared results to the reference devices. The greatest discrepancies were on the indoor treadmill and rowing machine workouts, where the Samsung device results were up to 50% different (e.g. estimated calories burned on the rowing machine were approximately 50% less than both reference devices, and less than expected when compared to manual calculations). Also, the heart rate average and maximum varied significantly on walking and treadmill, with the Samsung device consistently recording readings higher than reference devices.
- Bluetooth connection to phone. The Samsung band periodically lost connection to my phone if I walked from the room where the phone is located, to another room approximately 30 feet away. As a comparison, I was able to go almost anywhere in my two story house with the reference devices without losing connection. As both devices use the Bluetooth 5.0 standard, the reason for this variance is unclear, although it may be related to different minimum signal thresholds established for connectivity for the devices.
- Battery life (based on at least one or more workout per day, Google Calendar notifications, sleep tracking nightly) was ~4.5 days. As I was doing quite a bit of test activity, I believe it would last longer under normal operating conditions.
- Samsung should consider either changing the band design, or make traditional type watch bands available as an accessory.
- Samsung should analyze, and revise as necessary, the algorithms used for computing heart rate, distance and calories burned for different use cases and user profiles. Algorithms should be tailorable to accommodate the individual's profile (age, etc).
- Samsung should analyze, updating as necessary, the Bluetooth communications software functionality for the device to obtain greater reliability and increased range.
- Inclusion of the ability to use the connected phone GPS would be a plus.
