What is Pelagia?

Pelagia is an offline-first dive log built by scuba divers for scuba divers—made to feel like the logbook you always wanted on the boat, and the journal you’ll want to read years later. Offline-first means you don’t need an Internet connection, so it works wherever you do. It’s a great fit whether you want clean, reliable records pulled straight from your dive computer, or you want to capture the whole story of a dive: conditions, team, gear, how it felt, and the photos or video that bring it back. It runs across iOS, Android, macOS, Windows, and the web, so your log stays with you wherever you plan, dive, or debrief.

Features

Bluetooth Dive Computers

Direct Bluetooth downloads from many dive computers through the app’s native import flow, with guided setup, progress tracking, and selective import. Includes support for Shearwater and Suunto models.

Logbook Imports

Easy migration from other logbooks: DiveLog is fully supported today, and the import architecture covers Subsurface/UDDF formats—making it straightforward to bring data over from MacDive and other common systems.

Fast Entry, Deep Analysis

A beginner-friendly flow with real power under the surface: quick entry, autosaving edits, and approachable screens paired with deep stats, dive profiles, filtering, and gas-usage analysis.

Journaling Your Way

Flexible logging that matches your style: minimalist record-keeping when you want it, or rich journaling with conditions, activities, marine life, notes, ratings, and media when you want the experience preserved.

Everything In One Place

Complete dive context in one place: sites, trips, buddies and instructors, equipment loadouts, cylinders, gas mixes, and multi-tank configurations.

More About the App

Pelagia is built for remote trips and unreliable signal—your data stays on your device, dependable and fast. The app includes a statistics dashboard, achievement badges for milestones and wildlife sightings, and multiple themes including high-contrast options. Development is active and ongoing: new features land regularly, and improvements are shaped by real diver feedback.

Built for the long haul

Keep your diving history readable and trustworthy—whether it’s a quick training dive or a bucket-list expedition.
