One problem, one audience. If we cannot say who an app is for, we do not build it. Focus does not shrink an app, it sharpens it.
Working is not enough. We run design and code together from day one. If it does not feel good, it is not finished.
One thing that fully works beats five that half work. We keep the scope small so the quality does not have to be.
The goal is not downloads. If the app is still being used six months in, we did our job. We keep what we ship maintained: apps worth using, kept usable.
