I'm not looking to create the next IG, but I like how you can share your photos and description and let other app users see, like it, and leave a comment. I'm not a developer so I'll need to outsource all the work. Just want to know what it would take, besides the coding, for the app to have that feature. Basically a feature for users of the app to see what others have written. Can be liked. Commented on. Would I need a web server? Would it be expensive in your opinion to maintain it? Lots of headaches? And any other insights. Thanks for any info.
