For idea validation you need monetization. I heard about this a lot in Indie Hackers but still, I didn't listen. I spent 3 months in release until I felt it's time to add monetization to my app.
But for real I don't feel that my product is worth what I'm asking for. But now I'm unemployed and I gave myself a short runway of 3-5 months to see if my app has the potential to make money. So in my situation, I don't have space for feelings. I'm searching for numbers that will give me answers.
I'm hoping the next milestone will be about the first sale.
