About

Keep your aquarium care organized. "AquaMaster: Aquarium Log Book" keeps water readings and care records together, from your first aquarium to multiple planted or reef tanks. 【Free to Start】 Get started for free with 1 tank. Hobbyist supports up to 3 tanks; Pro and the Lifetime plan support unlimited tanks. Compare the features of each plan in the app. 【Core Features to Protect Your Aquarium】 ● Tank Butler Choose a date to review recorded water readings, maintenance, and tank member information up to that date. Member names, quantities, and species or brands reflect the current records. Share a text summary or receipt-style image with a friend or someone helping care for your tank. ● Built for iPad - Browse your tank list and read tank details side by side in a native two-column layout. - A new iPad dashboard greets you with today's weather and a summary card for each tank. - The calendar and water parameter charts stretch out to fill the bigger screen. ● Multi-Tank Management - Manage freshwater, reef, planted, and shrimp tanks, each with its own water readings, maintenance schedule, and records. ● Tank Members - When did this fish arrive? How many shrimp are on record? When did you add that filter? Track fish, shrimp, snails, aquatic plants, and equipment — species or brand, quantity, and date added. - Custom categories and display order; archive a member with an optional reason (died, rehomed, sold) and the record stays, building a complete care history. ● Scientific Water Quality Tracker - Log pH, NO2, NO3, water temperature, salinity, and other critical parameters with ease. - Follow changes in water readings with charts. - View local weather alongside your tank information with WeatherKit. ● Log Search & Note Tags - Find any entry in seconds: type a few words or tap a log type, and matching entries show up with notes and a running count. - Vitamins this morning, bloodworms tonight — tap a tag instead of retyping the details. Tags are searchable too. ● Smart Maintenance Reminders - Set recurring reminders for water changes, feeding, filter cleaning, and dosing. ● Test Strip Camera Scanner & Quick Entry - Snap a photo of your test strip and Vision technology reads the color blocks to pre-fill your water readings for you to review before saving. - Built for real-world lighting: adjust the readings on screen before saving if needed. ● Home Screen Widgets - Keep an eye on your aquarium at a glance — no need to open the app. - Small widget shows your next reminder and its tank; Medium widget switches between your latest readings and today's/tomorrow's reminders. - Fully localized to match your in-app language (9 languages). ● Your Data Stays Yours - All your tank logs and water parameters are stored in your personal iCloud account, encrypted and synced via Apple CloudKit — never uploaded to our own servers. - Switch devices anytime; as long as you're signed in with the same Apple ID, your data picks up right where you left off. - Available on the free plan too — this isn't a paid-only feature. --- 【One-Time Purchase Option】 Prefer not to subscribe? We also offer a "Lifetime" plan. - Pay once to unlock unlimited tanks and advanced analytics for good. - No auto-renewal, no recurring charges — ever. 【About Auto-Renewable Subscriptions】 Hobbyist supports up to 3 tanks, while Pro supports unlimited tanks. See the in-app plan comparison for the other features included in each subscription. - Subscription cycle: Monthly auto-renewal. - Payment will be charged to your iTunes Account at confirmation of purchase. - You can turn off auto-renewal at any time by going to your iPhone's Account Settings after purchase.
