I have an AMAZING idea for an App

[Objective]

What is it that'll make people want to come back to an app with so much competition elsewhere that already has millions of users? Seems like a lot of work for something I can do more specifically with other apps, and I'm sure that if this worked people would have already made it. People already have Tiktok, Instagram and so on, what makes this different other than knowing where people know other people from? People seem to want more privacy, not less of it. Mutual friends and friends list is a thing. What's your demographic and how will you reach them?

How will you make money off of this? Have you thought about server costs and so on? Videos take a shitload of space and it's expensive to run. I hope you've planned for stuff like this as well before you're making an app that you can't afford to run.

"PM me if you want to get RICH" screams: I don't believe enough in this idea, please pay or make it for me.

I'm not meaning to shit on your idea, I just don't believe in it. Make me believe in it.
