Dido is a brand that mainly promotes wearable devices with intelligent health monitoring function. The overall design is very young, not only suitable for middle-aged and elderly people to wear, but also fashionable and cost-effective. This watch can not only monitor the user's own blood sugar value at any time, but also record the measured parameters, and automatically upload the results to the mobile APP, so that users can intuitively see the blood sugar changes in a period of time with their mobile phones, so as to better use drugs.
