About
Log your reef in 30 seconds. Never lose a reading again. ReefLog is a water parameter tracker built for saltwater and reef tank keepers. Faster than a spreadsheet, smarter than a paper notebook. WHY REEFLOG - 30-second logging: A quick-entry sheet tuned to your test kits. Tap in your numbers and get back to enjoying your tank. - Unlimited everything: Unlimited tanks, unlimited tests, unlimited history. No monthly measurement caps, no extra fee for a second tank. - Trends you can actually read: Clean charts with safe-range bands, so a slow alkalinity drift stands out weeks before your corals show it. - Reliable reminders: Test-day notifications that fit your schedule, so consistency stops depending on memory. TRACK WHAT MATTERS Alkalinity (dKH), Calcium, Magnesium, Nitrate, Phosphate, Salinity, Temperature, and pH. Input fields match your test kit's units and precision. MADE FOR YOUR TANK Tell ReefLog what you keep - SPS, LPS, soft corals, or fish-only - and it applies matching target ranges. SPS keepers get the strictest profile; fish-only tanks get sensible, forgiving bands. YOUR DATA, YOUR CONTROL - All records are stored on your device - No account required - Import from CSV (moving from a spreadsheet or another app) - Export your full history to CSV anytime - Attach photos to track coral growth and coloration MULTI-TANK READY Keep a display tank, a frag tank, and a quarantine tank? Switch between them instantly. Every tank gets its own log, charts, and target ranges. PRICING ReefLog is a paid app. One price unlocks every feature - choose weekly, annual, or lifetime. Subscriptions auto-renew and can be managed or canceled anytime in your store account settings.
