ReefLog is the fast, private way to keep your saltwater or reef aquarium stable — and the only log that tells you what to actually do about your numbers. Most aquarium apps just store readings. ReefLog reads the trend and turns it into action: it sees your alkalinity slipping, projects when it will fall out of range, and recommends the exact dose to hold it steady. LOG IN SECONDS • Track alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature, and pH • Sensible ideal ranges built in, with instant in-range / out-of-range feedback • Back-date readings and fix mistakes easily SEE TRENDS BEFORE TROUBLE • Clean history charts with the ideal range shaded in • A "Today" view that surfaces what needs attention, ranked by urgency • Early warnings when a parameter is trending out of range KNOW EXACTLY WHAT TO DOSE • Calibrate your supplements once to your own tank — no guessing a brand's strength • Get precise maintenance doses that offset your tank's real consumption • Get correction plans that respect safe daily raise limits STAY ON SCHEDULE • Maintenance reminders for water changes, dosing, and filter care • Per-task notifications, fully on-device PRIVATE BY DESIGN • Everything stays on your device — no account, no cloud, no tracking • Your tank data is yours Everything in ReefLog is free for a single tank — full history, trend charts, the dosing planner, maintenance reminders, and CSV export. A one-time premium upgrade adds unlimited tanks so you can track every system you keep — pay once, yours forever. No subscription. Whether you run a nano reef or a mixed reef showpiece, ReefLog helps you keep it stable with less guesswork.
