Nerite: Aquarium & Reef Log

Nerite is the all-in-one companion for aquarium and reef keepers — your fish and corals front and centre, your water chemistry tracked behind them, and a maintenance schedule that never slips. Everything stays private on your device. YOUR FISH & CORALS, FRONT AND CENTRE Every animal gets its own profile — photo, care level, reef-safe status, and notes. The Home screen greets you with your livestock and a daily water-health summary, so you see the tank, not just the numbers. BUILT FOR YOUR TANK TYPE Reef, marine fish-only, planted, or freshwater — Nerite seeds sensible target ranges for the parameters that matter to your setup, from pH and ammonia to alkalinity, calcium, and magnesium for reef chemistry. SEE YOUR WATER AT A GLANCE A parameter grid with mini trend lines shows in one glance whether everything's in range — tap straight into a full history and chart for anything that isn't. MAINTENANCE THAT DOESN'T SLIP A real calendar for water changes, dosing, filter media, and custom tasks, with recurrence built in. Reminders fire when a task is due, and overdue tasks are impossible to miss. A WIDGET FOR YOUR HOME SCREEN See your tank's water status, next maintenance task, and livestock at a glance — on your Home Screen and Lock Screen, without opening the app. TRACK YOUR GEAR Pumps, skimmers, heaters, lights — with service intervals so nothing fails quietly. A TIMELINE OF YOUR TANK'S STORY Every reading, completed task, new addition, and serviced piece of equipment rolls up into one chronological timeline — the fastest way to spot what changed right before a problem started. BUILT-IN REFERENCE A species compatibility guide, a disease and parameter glossary, and calculators for tank volume, water-change percentage, salinity, and dosing — with the formula shown, not a black box. SCAN A TEST STRIP (PRO) Point your camera at a test strip or vial and Nerite estimates the reading for you — informational, always shown alongside a reminder to confirm against your kit's printed chart. PRIVACY-FIRST, OFFLINE-FIRST Your tank data lives on your device. Nerite doesn't require an account and doesn't track you. FREE, WITH A ONE-TIME PRO UNLOCK Start with one tank and the core tracking loop, completely free. Pro removes the tank limit, unlocks the dosing calculator, camera scan, and full data export — one purchase, no subscription, yours forever. Made by Appricode Software Consultancy LTD.
