Aquarium Log & Tracker: Nerava

Fish Tank Care & Water Tests

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Log water tests in seconds, follow care routines, spot changes early, and keep every aquarium's history clear. Aquarium care, made clear. Log water tests, follow care routines and see how your tank changes over time. Nerava brings your aquarium's measurements and maintenance into one clear history, with profiles for freshwater, planted, reef and shrimp tanks. LOG WATER TESTS WITH EASE Record temperature, pH, ammonia, nitrite, nitrate and more. Choose the parameters and units you use, keep previous readings in view and enter several results in one water check. SEE YOUR WATER TRENDS Follow individual parameters on clear charts. See care events alongside your readings, inspect past results and revisit how your tank has changed. STAY ON TOP OF TANK CARE Schedule one-off or repeating water checks and maintenance tasks, with optional reminders. Complete a task by logging what you did, or snooze or skip it when plans change. SEE WHAT CHANGED Compare recent readings with their dates and review care events recorded between them. Schedule a follow-up water check when you want to measure again. Recorded events provide context; they do not establish the cause of a change. KEEP TESTS AND CARE TOGETHER Record water changes, filter cleaning, feeding and other care events in the same timeline as your tests. Revisit and edit your records as your aquarium's history grows. KEEP A COPY OF YOUR HISTORY Export measurements and care events as CSV, or save a complete Nerava backup that you can restore later. You choose when and where to save your backup. START WITH ONE AQUARIUM Use one aquarium with unlimited manual logging, your complete editable timeline and individual seven-day charts. Care schedules, follow-up checks, exports and backups are also included without a subscription. NERAVA PRO An optional subscription unlocks additional aquariums, longer chart ranges and multi-parameter comparisons. Existing aquarium records remain available if your subscription ends. Make your next water check the start of a clearer tank history. Nerava does not replace advice from an aquatic veterinarian or experienced professional in an animal-health emergency.
