The main takeaway of this project was to successfully build an app that would help many people with different Bluetooth devices by showing them how close they are to their devices and lead to their location. It was challenging but also fun since Bluetooth technology is fickle so it was rewarding to be able to build something that can help people on a daily basis with such contemporary common issues.


When it comes to design, the most fun and challenging part was to implement a good finding tool that would bring back great results, and after a complex analysis we came up with a fun solution, we chose a bright and friendly theme that everybody would find pleasing, junior or senior.


Following the design, one other fun takeaway of this project was creating the symbolic dog character, Rex the Sniffer. Integrating Rex in the UI of the app was an entertaining experience as it was challenging, but also extremely pleasing because we got the chance to play the artist and be craftsmen.
