The App
Designed like an instrument.
Built for modern aquarium keeping — this reef tank tracking app and freshwater aquarium log is designed to make every ecosystem feel intuitive, immersive, and alive.
Onboarding
Choose your ecosystem. Start in seconds.
Tank Dashboard
Your entire ecosystem at a glance.
Parameter Tracking
Clean charts, beautifully rendered.
Built from inside the hobby.
Made by a keeper, for keepers.
Reef Theory started as a way to make aquarium keeping feel less scattered. Between testing water, tracking livestock, remembering maintenance, and watching tiny changes in a tank, hobbyists need something better than notes, spreadsheets, and random reminders.
This aquarium tracking app is being built by an aquarium keeper, for aquarium keepers — starting with the real problems we deal with every week.
