An app studio on godaisy.io
We build apps that read rivers, seas, skies, gardens and kittens.
And tell you plainly what they mean. Seven apps live in the stores, one of them built for a client, and one more on the way.

What we're good at

Which sea fish are likely feeding on your coast today, and why, read from satellites, buoys, weather feeds and catch reports.

Built for a client
Hungerford Fishery
A members' app for a historic chalk-stream fishery on the Kennet, live on the App Store since September. It runs the club's back office too: members, guest tickets, and river closures read straight from the club's own news.
We couldn't be happier with the app Damian Rafferty of Go Daisy built for us. From our very first conversation, he took the time to understand how the fishery actually runs, and it shows.

A game-changer for Hungerford Fishery
We couldn't be happier with the app Damian Rafferty built for us. From our very first conversation, he took the time to understand how the fishery actually runs, and it shows.
The app is intuitive, reliable, and exactly what our anglers needed. Checking conditions, catch reports, guest booking and keeping up with fishery news are all effortless now.
Damian was a pleasure to work with throughout: responsive, patient, and quick to turn feedback into improvements. He delivered on time, explained everything in plain English, and has been generous with support since launch. Our members love it, and it's saved us hours of admin.
If you're looking for a developer who combines real technical skill with genuine care for the finished product, we can't recommend Damian highly enough.

Coming January 2027How we work
From a short brief to an app in the stores
- 1
Tell us who it's for
A few lines is plenty: who will use it, and what it should do for them.
- 2
We build it and ship it
Web, iPhone and Android from one codebase, in your colours and your words. Typically 6–10 weeks from brief to the stores.
- 3
We keep it running
Content and fixes can reach your members the day they're made, without waiting on app-store review.
Who we are
Daisy Studio is Damian Rafferty, who has spent three decades making digital things people actually use.
He started as editor of Fly, a global music magazine, in 1995. Since then he has produced companion apps for TV formats such as Britain's Got Talent, The Voice UK and Love Island Sweden, and shaped digital content for the Royal Botanic Gardens, Kew, Royal Museums Greenwich, ActionAid and the Department for Education.
Now based in Asturias, he builds apps around the things he cares about: rivers, the sea, gardens, getting people together and, yes, kittens. Each one starts with a question people ask before they head out, and answers it plainly. The studio runs through Fly Industries Ltd, his consultancy since 2007, with a small group of collaborators.
