A great budget SmartWatch for iPhone — a balance of price, features, and convenience.
8 December 2025 
A great alternative for those who want "smart" watches without overpaying for show-off features. The gadget is light, convenient, fast, and has almost everything necessary for daily use by iPhone owners: notifications, basic fitness tracking, convenient gestures, and a good screen.
* Wonderful Retina OLED LTPO display with Always-On feature and sufficient brightness even on sunny days;
* Well integrated with iPhone: messages, calls, Apple Pay, quick access to music, navigation, etc. — convenient for everyday use.
* The small battery requires daily charging (just like all the watches from Apple);
* The basic model lacks advanced functions and sensors.
