About

Libro Watch

Features
Read full description

Libro Watch APP is a companion application for smartwatches. Its main functions are as follows: 1. One of the main functions of the APP is to push incoming calls and SMS/MMS received by the mobile phone to the associated smartwatch so that you can answer and view SMS/MMS on the watch; when the watch rejects the call, you can quickly reply, and the APP will send a pre-configured SMS to the caller. It should be noted that the APP will request "SMS and call log permissions" to implement these functions. Without these permissions, the application will not be available. 2. Record the heart rate data collected by the smartwatch and display it in the form of line graphs and bar graphs based on the heart rate data; 3. Record the exercise data collected by the smartwatch, including steps, cadence, distance, etc., and display it in the form of line graphs and bar graphs; 4. Record the sleep data collected by the smartwatch and display it in the form of line graphs and bar graphs; 5. Use the watch to start exercise or fitness; 6. Set reminders and alarms for the smartwatch. The data on the APP is not used for medical purposes, but only for general health/fitness purposes.
