Inspiration
I want to build a solution for this Hackathon because I have never done any Hackathon before. I am planning to build this whole app in public. And hopefully share my knowledge and my journey while I build this in coming two months I can already see that people are jumping in and helping me where I need to improve. I'm hoping to meet new people and follow you iOS steps and other on social platforms to learn more from them in future as well.
