Tk71pro Smart Bracelet for Android and iOS

The allentian Tk71pro is a wearable device built for men who want continuous health insight on a 1.47 inch AMOLED screen. It tracks heart rate, blood pressure, blood oxygen, sleep patterns and daily steps while delivering call and message alerts directly to the wrist. The yellow silicone strap and aluminium alloy case suit everyday sport use.

Sustained monitoring with magnetic charging

Battery life exceeds 21 days on a single charge, so the bracelet records metrics overnight and through extended workouts without daily top-ups. Magnetic charging restores power quickly, and the life-waterproof rating protects the sensors during sweat, rain or hand-washing. Touch and button controls stay responsive during long sessions.

Health sensors that decide the fit

The combination of heart rate, blood pressure, blood oxygen and sleep tracking in one band determines whether this model meets a buyer's wellness goals. Users who need clinical-grade glucose or uric acid readings will find those functions absent. Builders wanting built-in GPS or third-party app ecosystems should look elsewhere.

Questions about this item

How much power does the 1.47 inch AMOLED screen and continuous monitoring draw during all-day wear?

The 50 g bracelet runs over 21 days on a single magnetic charge, so daily power draw stays very low even with heart-rate, blood-oxygen and sleep tracking active.

What phone and software does the Tk71pro need before it can show notifications and health data?

It pairs with any Android or iOS handset within a 5 to 10 m wireless range; the companion app handles call, message and app alerts plus all fitness records.

Will the magnetic charging cable and silicone sport strap work with older smartwatch accessories I already own?

The cable and 50 g aluminium-alloy case are specific to this model, so legacy docks or bands from other brands will not fit or charge the Tk71pro.
