If you're going to have people close to you testing it with no real worries about user activation, engagement, etc. just get an alpha out there and start getting feedback from real users. Once you've driven out most of the bugs and the app is fully functional, move it to beta and start actively trying to get users. During this stage, you should be continuing to fix bugs, listening to user feedback, and iterating as necessary. It will never be too early to "ruin it"; if the idea has legs, users will be more forgiving in the early stages and will most likely give you really good feedback on how to improve the app. Just get something out there and start learning from users. I too am a perfectionist, but you just have to bite the bullet and get it out there. Remember, "great artists ship."
