Contributions summary:Ian focused on improving the Android application within the repository. Their work primarily involved resolving UI bugs related to the scanning functionality, and optimizing the user interface by hiding unnecessary elements. They also worked on improving the application's interaction with the backend by sending URL initially to PWS, and by detecting and decompressing gzipped data. Furthermore, they added and optimized the data transfer rate using BLE, which involved patching and monkey-patching to improve efficiency.
