Purpose and audience

The allentian Gt40 is a wrist-worn smartwatch built for everyday users who want health insights and phone notifications without a bulky device. It pairs with Android and iOS phones and delivers core tracking in a lightweight 150 g plastic case. The medium silicone strap suits average wrists and the sporty styling fits casual or active wear. Buyers who need built-in GPS, onboard music storage or third-party app ecosystems will not find those features here.

Capacity and headroom

The watch monitors steps, heart rate, blood pressure and sleep, then syncs summaries to the companion app for trend review. Bluetooth calling and voice-assistant access work within a 5 m wireless range, while remote-camera control and smart reminders handle daily convenience tasks. Battery life stays under seven days per charge, so weekly wireless top-ups become routine. Users who expect multi-week endurance or continuous SpO₂ tracking will hit the limits of this hardware.

Build and daily use

A TFT touchscreen combines with a physical button for navigation, and the IP-rated life-waterproof shell survives splashes, sweat and rain. The package includes the host unit, a proprietary wireless charging cable, manual and box. Silicone strap keeps the sensor array in contact during workouts, while the plastic case keeps weight low. Anyone requiring sapphire glass, metal construction or user-replaceable bands should look elsewhere.

Questions about this item

Will the 150 g Gt40 feel heavy if I keep wearing my traditional watch on the other wrist?

At 150 g the Gt40 is light enough that most users hardly notice the extra weight when wearing a regular watch on the opposite wrist.

How do I confirm the heart-rate sensor and blood-pressure measurement are working after I pair the watch?

Open the Fitpro app, start a real-time heart-rate reading and a blood-pressure check; both should return values within seconds if the sensors are functioning correctly.

Does the box contain a wireless charging pad or only the magnetic cable shown in the packing list?

The packing list includes the host, manual, charging cable and packing box; a separate wireless charging pad is not supplied and must be purchased if you prefer pad charging.
