Built to make aquarium keeping easier to understand.
Reef Theory is a modern aquarium tracking app being built for reef, freshwater, planted, nano, and pico tanks — created to help hobbyists log care, understand trends, and build better routines.
Why we exist
Aquarium tracking should feel better.
Aquarium keeping has evolved fast, but the tools used to track it still feel scattered. Many hobbyists rely on notes, reminders, spreadsheets, screenshots, and memory to manage water tests, livestock, dosing, maintenance, and tank changes. Reef Theory is being built to bring all of that into one clean, modern place.
What we believe
One app for living systems.
Freshwater, planted, reef, nano, and pico tanks may look different, but they all depend on the same habits: testing, observing, logging, maintaining, and learning from changes over time. Reef Theory is built around that shared rhythm.
Where we're going
Built for the long term.
Reef Theory is being built carefully, starting with the core tools aquarium keepers need most: tank dashboards, parameter logging, care tasks, livestock tracking, and clear history. Future updates will expand into deeper analytics, equipment logs, integrations, and community features.

The Mission
Make aquarium keeping feel clearer, more organized, and more modern — without making it more complicated.
Founder Vision
Reef Theory started from a simple frustration: aquarium keeping is beautiful, but tracking it can feel scattered. This app is being built to give hobbyists one clean place to understand their tanks.
One Ecosystem
From planted aquascapes to SPS reefs, every aquarium is a living system with patterns worth tracking.
For the Community
Reef Theory is currently in private beta, and real feedback from aquarium keepers will help shape what it becomes.
