Problem

North Sea surfers hop between forecast sites and still drive to a flat beach. They needed one call per break.

Build

An iPhone app built with Expo and React Native, on a forecast backend we run ourselves. Each of the 65 breaks is scored against its own offshore wind, tide and swell window.

Outcome

On the App Store, with a spot page on this site for each of the 65 breaks.

Problem

Anglers at sea and on fresh water plan from weather apps built for someone else. They needed forecasts, a catch log and species ID in one place.

Build

An iPhone app built with Expo and React Native. Photo species ID runs on a PyTorch model behind a FastAPI service we host. Basemaps and species data can be downloaded for use with no signal.

Outcome

On the App Store since April 2026, now on version 5.0.0.

GILLI fishing pageApp Store

Problem

Women track their cycle, water, sun and mood across separate apps, and most of those apps want an account and a server. Freyja keeps all of it in one app, on the phone.

Build

A Swift app for iPhone with no server and no account. The assistant runs on Apple's on-device model, answers from the user's own logs and declines medical questions.

Outcome

Free on the App Store for iPhone and iPad.

Outcome

Lake depth charts in GILLI.

Problem

The studio needed one site for its services, journal and apps. GILLI and NORDR had to look like their own apps.

Build

Next.js with next-intl and Tailwind, hosted on Vercel. The studio, GILLI and NORDR are three design systems in one codebase, each with light and dark mode.

Outcome

Live at pelagiclabs.io in English, Swedish and Dutch. The NORDR page is also in French, German, Danish and Norwegian.
