With all my side projects and even the ones I was working on for different startups I always struggle with getting early feedback, its critical cuz I don't want to waste time on something nobody wants to use. Especially when the app in very early stage and you are not ready to lunch on PH for example. Sharing with friends is not really effective since they are not 100% objective.
Do you have this issue? how do you collect constructive feedback from your early users?
