Multiple brands including Realme, Realme TechLife, and Dizo now operate under Realme's aegis, benefiting from the company's research and development capabilities, sales and service network, and brand reputation in India. Realme TechLife has a rather varied range of products in India, including vacuum cleaners, wireless earphones, and smartwatches. The product I'm reviewing here is the Realme TechLife Watch S100, an affordable smartwatch that promises a lot of features for the price.
Realme TechLife Watch S100 Summary
The Realme TechLife Watch S100 is an affordable full-sized smartwatch, with a 1.69-inch colour screen that makes the device work well to view and read notifications. There are also various fitness and health tracking functions including heart rate, blood oxygen, and body temperature.
Although very affordable and decent for notifications, the device falls short when it comes to fitness and health tracking, with iffy step counting, and inaccurate heart rate and SpO2 readings under most circumstances. It might be worth considering this if you want an affordable device with a big screen, but a decent fitness tracker will likely serve you better.
