Hello everyone , need some guidance

Hi ,
I’m Ravi from India ,
I have some ideas for apps or adding more features to apps but I don’t know where to submit ,
I’m not a coder , I really appreciate any guidance on this

thanks in advance

If, for example, the app is open source, look for the link provided by them, then you can submit it there. One example of hosting site for open source projects is GitHub.

Or try to search the app on GitHub. GitLab is another one.
