In this final round, the 6 teams that won the top prize in the preliminary rounds held online and in real life, as well as the 3 teams that were selected from the top prizes in each preliminary round, will participate, and within a limited time of 24 hours they will be able to choose their favorites. We competed in app development based on the theme.

As in previous years, while questions were asked about how to interpret the theme and how to turn it into an app, the key point seemed to be how to effectively utilize the rapidly evolving generative AI. I also saw a scene where the generation AI was outputting code. Another important factor was how to make the app look attractive.Some teams have members who specialize in presentations.It felt like the concept of a hackathon had changed dramatically.
