Tuya App and Smart Life App are both official Tuya App. The only difference between the two is that the Tuya App uses the Tuya logo and elements, while the Smart Life App removes all Tuya logo and elements. The data of the two apps are independent of each other, and data such as Tap-to-Run and Automation in the app cannot be transferred. If you need to transfer the device, you need to remove the device from one app and add it again in another app.
