Its 1.43-inch AMOLED screen provides crystal-clear 466 x 466 resolution with Always-On Display (AOD) support, ensuring vital information is always visible. The standout design feature is the magnetic strap—available in stainless steel or bamboo-style silicone—which offers a secure, infinitely adjustable fit that transitions perfectly from the gym to the boardroom.
Technologically, the i28 Ultra is one of the first in its class to integrate AI functionality via Da GPT, allowing for more interactive voice assistance. It also caters to specific user needs with a built-in Muslim prayer function (including prayer time reminders and Qibla assistance) and real-time stock market trend tracking. For health and fitness, it utilizes the VC30F sensor for accurate heart rate and SpO2 monitoring, alongside 100+ sports modes. With an IP68 waterproof rating and a 260mAh battery providing up to 7 days of life, it is built for reliability in any environment.
