Show HN: Need Advice about WhereToGo.dev

My first small ever launched Application. I am super excited and i really like it. Showed it to friends and family and got some feedback.

But i am struggeling about marketing. I dont want to make a ton of money, i want to help people with it, so thats why it is free for now.

- Should i start gathering emails? - Where can i promote such app? I like doing some buildInPublic on X

It would be great to receive some feedback!
