It's all about iterations
Poorly designed wireframes, but the most important part: is it working?
Do we have all the screens we need? This is how we started, with wireframes for screens.
Then we improved it. And again, and again...
and honestly, when we have some free time, we're still working on it.
This is how I envision product design: you start super small, you ship it fast and gather users feedback,
and make it more beautiful, more useful, step by step.
