Cvrček, D. Web and mobile application for effective using working hours. Diploma thesis. Brno, 2018. This diploma thesis is focused on improvement of the work efficiency. The goal is to study existing technique called Pomodoro, design and implement a mobile and web application, which can provide the user an overview of performed work and its efficiency. Further, a mobile application for smartwatches which will be implemented for tracking of the user behavior and related personal notifications. All described applications are tested on a group of selected users.

The market for wearable devices is continuously growing and has seen an in- crease in interest and demand this past year, specifically smartwatch devices. With several big players entering and trying to take place in the market the number of devices and platforms grow. This leads to device and software fragmentation like the one seen in the world of smartphones. In this paper I discuss and compare the two smartwatch platforms Android Wear and Apple Watch in terms of possibilities, limitations and differences. Research is done to find cross-platform development possibilities for these platforms. Extensive theoretical background of both APIs is researched and presented. An app for both smartwatch platforms is developed with integration of the WebSocket protocol to function as a remote control for a Video-On-Demand web service. This is done to showcase the cross-platform possibilities and differences of the platforms. As a result the biggest differences are out- lined and a conclusion is made that cross-platform development for these platforms can be challenging but is possible on certain levels.
