A few months ago I started looking into EMDR therapy. It was helping, but every app I found was either full of ads, painfully basic, or charging $80/month for what amounts to a dot moving across a screen. Then I remembered I actually know how to build things. So I started building my own tool. And then something unexpected happened.
