Which I would not personally sell for less than 50k.
But again it doesn't have a user base which is why they are shooting for 25k.
If you personally think its possible to get a user base on your time then try it.
I personally would try it just because it looks like a really solid app even though its in alpha.
But I don't develop apps or invest in anything so I would wait for more people to reply who actually have solid experience with this.
I mean I am assuming you know this app has potential to grow but at the same time kinda sounds like you need the money. Which is why I took the time to reply and upvote it so other people can help
