Smartwatch for Android and iOS Users

The allentian HK9 is a wearable built for daily health tracking and connected alerts on Android and iOS phones. It records steps, heart rate and sleep while delivering Bluetooth calls and intelligent reminders to the wrist. A TFT screen running at 120Hz keeps motion smooth for quick glances.

Check Phone Compatibility and Charging Setup

Verify that the paired handset runs a supported Android or iOS release before ordering. The watch charges wirelessly and weighs 140g with its aluminium alloy case and TPU strap. Wireless link range spans five to ten metres, so keep the phone within that distance for calls and notifications.

All-Day Monitoring With Weekly Recharge

Continuous sensors for step counting, heart rate and sleep run throughout the day without a bulky battery pack. Typical use returns less than seven days per charge, so plan a weekly wireless top-up rather than daily plug-ins. Life waterproof rating handles sweat and rain during extended sessions.

Questions about this item

Does the box include a charger or do I need to buy a wireless charging pad separately?

The watch charges wirelessly and the packing list is described as standard; a compatible wireless charger is required if one is not already owned.

Which colour option should I choose between the listed White and Black versions?

Both White and Black share identical specifications — 140 g weight, aluminium alloy case, TFT screen, TPU strap and the same feature set — so the choice is purely aesthetic.

What does the 120 Hz screen refresh rate mean for daily use on this watch?

The 120 Hz TFT panel makes menu scrolling, notification swipes and workout animations appear smoother compared with lower refresh displays.
