Smart watch for daily fitness tracking

The allentian H13 Gt20 is a wearable device built for Android and iOS users who want basic health monitoring on their wrist. It offers step counting, heart rate monitoring, sleep tracking and intelligent reminders in a single unit. A TFT screen and touch-button operation keep controls simple. The 140G weight sits lightly for all-day wear.

Seven-day endurance with magnetic charging

A full charge delivers up to seven days of typical use before the magnetic cable is needed again. Continuous heart-rate tracking or frequent notifications will shorten that window. Life-waterproof rating handles sweat and rain but not swimming or shower pressure. Wireless range extends to five metres from the paired phone.

Replaces basic bands and missing reminders

The watch upgrades from simple step counters by adding heart-rate data and sleep insights. It also removes the need to check the phone for every alert. Buyers who need built-in GPS, contactless payments or third-party app support will not find those features here. The jump is worth it for core metrics and phone-free convenience.

Questions about this item

Will the H13 GT20 smart watch pair with my older Android phone running an earlier OS version?

The watch is compatible with Android platforms and connects via Bluetooth within a 5 m range, so it should pair with most Android phones that support Bluetooth.

How can I verify the heart-rate monitor and step counter are working correctly after I set up the H13 GT20?

Open the companion app on your phone; live heart-rate readings and step totals appear on the dashboard and update in real time as you move.

Does the box include a power adapter for the magnetic charger or only the charging cable?

The packing list includes the host, manual and magnetic charging line; a USB power adapter is not supplied and must be purchased separately.
