M99 AMOLED smartwatch with 2.4″ display and HiSportPro app

M99 AMOLED smartwatch

The supplier lists a 2.4″ AMOLED touchscreen with 480 × 480 resolution, Bluetooth 5.4, GPS and the HiSportPro app. Calls, notifications and activity features are listed.

Connectivity needs confirmation before purchase: some fields state SIM and 5G/4G network support, while another says SIM is unavailable; complete supported bands for different countries are not provided. Wi-Fi, camera and memory are also described inconsistently: variants list 6/64GB or 8/128GB, while specifications state 6GB RAM/128GB ROM and other capacities. These functions are not promised without supplier confirmation. Battery capacity and runtime are not guaranteed. No verifiable water-resistance rating is specified.

Heart rate, blood oxygen, blood pressure and sleep readings are for reference only and do not replace medical advice.
