Hi, I'm new in this reddit,and I have a crazy idea, I want to build an app, but I honestly have no idea where to start,I know everything it has to do, and even the long term project, but I honestly have no knowledge in coding of any kind,could you help me with some pointers of where to start,what toold to use,I'm trying to learn and build as free as positive,as I can't afford right now to invest big money. Also are there any chances I can find someone to help me build it,for portofolio purpose,or shares from the app in case I can actually make money out of it.Please don't kill me, just a noob with ton of questions 😭
