If you look at the top Mac cleaning utilities today, they all share a similar design language: they look like a 2005 spaceship dashboard.
They have spinning radars, giant red warning signs flashing "YOUR MAC IS IN DANGER", and custom UI elements that look nothing like macOS. It s designed to create panic and force a purchase.
When I started building OptiClear, I decided to take the exact opposite approach. I wanted the UI to be almost... boring.
