Description

From the listing uploaded by “appupdater”.

LinkTo Health APP is a application for smart watches and has the following functions: 1: Record the steps, heart rate, sleep and other data collected by the smart watch, and display it in the form of charts based on the data. 2: You can set alarm clock and other reminder functions. 3: The APP can push the incoming calls and text messages received by the mobile phone to the associated smart watch, so that you can check the text messages and call status on the watch; when the app uses this function, it needs to request "permissions related to calls and text messages". After the user agrees, the smart watch will receive notifications of text messages and incoming calls in real time, bringing a convenient experience to the user; the user can also choose to refuse the permission without affecting the normal use of the app.
