The person behind it

Hello, I'm Coral.

I am an indie developer in Hull, on the east coast of England, and Coralia Digital is just me. I design the apps, write the Swift, draw the icons, test them, ship them, and answer the support email when something goes wrong.

I came to this from an MSc in artificial intelligence and data science, which turns out to be a useful background for building small software carefully. It taught me to be sceptical of my own results, to measure things before believing them, and to keep asking whether the clever solution is really better than the simple one.

Away from the screen I spin, dye and weave, which is where a lot of the sensibility in these apps comes from. Craft rewards patience and punishes shortcuts. So does software. My apps have no streaks that shame you, no manufactured urgency, and no interface designed to make leaving harder than arriving.

If you use one of them and something is broken, missing or annoying, please tell me. It is one person reading that inbox, and a good number of the features in these apps started life as somebody's email. coraliadigital@icloud.com
