I give it to my friends and ask them to do specific things. Most of the time they will point me to something i didn't know.

That's currently where I'm at myself. Do you feel that, that approach scales fine and you get a broad enough idea of where problems are for the general user and where you need to improve/change things?

It doesn't scale, in that you ideally want to test your app's UI/UX with first time users who haven't gotten used to your app's quirks yet. But it allows to catch a lot of stuff early on at the cost of buying them a coffee or a beer (if that).

You'll just learn things, but it won't scale at all. One of many reasons is that it's very specific people (it may not even be Your target users).
