Why Reef Trak does this better than any other reef app

Every feature — including Global Reef Index — is connected to the rest of the system: parameters, dosing, maintenance, livestock, equipment, photos, notes, calculators, and reports. No other reef app offers this depth of integration across iPhone, Android, and the WebPortal.

The broadest reef parameter coverage in any app
The deepest livestock and equipment records
The most reef controller integrations
AI-ready Deep Dive exports — only in Reef Trak
