Q3: Is the Js5 Smartwatch a good fitness tracker?

Absolutely—the Js5 Smartwatch is a capable fitness companion for everyday health and wellness tracking. It automatically monitors key metrics such as step count, walking/running distance, and estimated calories burned throughout the day. With real-time heart rate tracking, it helps users maintain optimal exercise intensity during workouts.

Q4: Can the Js5 Smartwatch measure blood pressure?

The Js5 Smartwatch includes a sensor system that estimates blood pressure using a combination of optical and electrical signals, along with algorithmic comparisons to standard physiological values. However, it's important to note that this measurement is not a substitute for medical-grade equipment. The readings should be considered indicative rather than clinically accurate. Factors such as wrist placement, movement, and individual physiology can influence results. For users monitoring hypertension or other cardiovascular conditions, we strongly recommend confirming any readings with a certified blood pressure monitor and consulting a healthcare professional. The smartwatch serves best as a trend-tracking tool to observe general patterns over time.

Q5: Is the Js5 Smartwatch waterproof?

The Js5 Smartwatch is designed with water resistance in mind, rated as splashproof and suitable for shallow-water activities. It can withstand exposure to rain, handwashing, and short periods of swimming in pools or calm waters. However, it is not fully waterproof and should not be used for diving, snorkeling, or prolonged submersion. High-pressure water (like showers or water sports) may compromise the seals. After swimming, it's advisable to rinse the device with fresh water and dry it thoroughly. This moderate level of protection makes it ideal for daily use and light aquatic activities, but users should exercise caution in more extreme water environments.
