rate: 75I do not work in the Korean yummai App Store app because it is for domestic use in China.
The product is good. However, I can not get it to work on the iPhone Korea app because it is not a regular Korean release. If you use mihome instead of the winmy app, it will be synced, but you need to turn on the app each time you measure because there is no automatic synchronization. And the US home does not have data linking with health apps or other fitness apps.Mar 06, 2019
