1.91-inch HD smartwatch with Alexa

The Yoever IDW20 is a new smartwatch that pairs with Android 6.0+ and iOS 9.0+ phones over Bluetooth. It offers a 1.91-inch LCD touchscreen, built-in Amazon Alexa, and the ability to answer or make calls from the wrist. A rotatable crown adds quick menu navigation, while over 100 watch-face styles let you personalise the look.

Health tracking under daily wear

Continuous sensors monitor heart rate, blood oxygen, stress and sleep around the clock, sending vibration alerts when readings fall outside normal ranges. The watch logs steps, distance and calories across 105-plus sport modes and adds reminders for hydration, alarms, fitness goals and women's health. An IP68 rating and 15 metres of water resistance mean it survives showers, rain and swimming sessions without interruption.

Bluetooth-dependent ecosystem

All smart features — Alexa queries, call handling, notifications, weather and camera control — require an active Bluetooth link to a compatible phone; the watch has no standalone cellular or Wi-Fi radio. SMS sending is not supported, so replies must be handled on the phone. Battery life varies with sensor use and screen brightness, and the lithium-polymer cell recharges via the supplied cable.

Questions about this item

Does the 1.91-inch LCD and always-on health sensors make the watch hot or drain the battery quickly during all-day wear?

The 1.91-inch LCD and continuous heart-rate, SpO2 and stress tracking run on a lithium-polymer cell; the watch is designed for 24/7 monitoring with vibration alerts instead of constant screen use to manage heat and power draw.

What phone and software versions do I need before the IDW20 can pair and show notifications?

You need a smartphone running Android 6.0 or later, or iOS 9.0 or later, with Bluetooth enabled to handle calls, Alexa voice commands and app notifications.

Will the IP68 rating and 15-metre water resistance survive the same showers and swims my older fitness band handled?

Yes, the IP68 rating and 15-metre water resistance cover showering, hand-washing and pool swimming just like typical older bands, but avoid high-velocity water or deep diving.
