The objective of this Treball Final de Grau is studying wearable devices and developing applications for them. This document contains a few concepts about Android applications and basic guidelines to program an application for Android Wear O.S. that could be followed by the reader for programming his own application. First of all, there is an explanation about the reasons for the device choice, thus comparing commercially available devices and performing an overview of the different O.S. used nowadays. The document presents an application that measures the heart rate through an optical sensor embedded in the wearable device. This application sends the data obtained from the sensor to another application developed in a smartphone. Bluetooth is employed for this purpose. With the objective of understanding how the application works, the document explains the methods used in the application. A guideline for application developers is also included so that a user could be able to develop a new application step by step using the Android Wear O.S. Finally we present some battery level tests on the wearable. We study the impact of the developed application on the battery level, thus evaluating the influence of the heart rate sensor and the use of the Bluetooth link between the applications, along with different scenarios for sending heart rate samples.
