What we make
From a route-tracking travel app to a risk-assessment tool for school trips, we try to keep everything simple enough to use without a manual.
Pebbls - Adventure Tracker

A small studio
Lisia Digital is founded and run by Simon Harvey, a Guernsey-based software developer, who works closely with his brother Adam Harvey across many of its projects. Their backgrounds span education, ecology and outdoor learning, and much of life happens outdoors: the office is often a desk in Guernsey, but just as easily the side of a mountain on one of Simon's bikepacking trips, or the deck of Adam's boat out at sea. They build practical tools that help people learn, explore and connect, and look after them end to end, from database design through to hosting and support.

Growth & SEO
We build software that solves real problems rather than abstract technical projects. Our approach is practical, ethical and environmentally conscious, focused on digital tools that are clear, useful and easy to use.
Get in touch
We're selective about new projects, but always happy to hear from people building something useful, thoughtful or a bit unusual. If you have a project in mind, or just want to connect, feel free to say hello.
