App: a forum to talk to software developers about new app ideas

Yo, I'm an business student, and I want to create an app, but I'm not a software developer, so I don't even no where to start. I've found this page, and here are the three ideas I wanted to develop:<br><br>- Marmita: an app to help people to organize their food, and to take home their leftovers. A lot of restaurants throw away food that would be used with the right appropriation, and people can use it depending on the moment.<br><br>- Communia: an app to symbolize world unity. The app would be a social media in which every post is seen by everyone in the world using the app. If an user liked a post, it would go up in the timeline; if not, it would go down. The algorithm would display the most world widely liked posts first. There are a lot of option to be developed.<br><br>- Heeder: an app to help people to organize their daily routines. It would a series of to-do lists in which you can mark the daily routine activities (like walking, working out, studying, etc).<br><br>I would love an feedback on these ideas, and some suggestions on how to proceed to implement then. This page seems awesome to talk to developers, so thanks for the feedback. <br><br>Edit: I've no idea what to do with the feedback. I would love some developers to contact me to help me to develop these apps. I've no idea what programming language to use, how to use a code editor, etc.<br><br>Edit2: I’ve created this post to feedback your page. I didn’t expect this massive feedback. Thank you so much for all the help. Since it’s Saturday in my country, I’ll spend the week studying the feedback and I would probably contact some of you next Saturday. Thank you, guys. You are awesome.
