【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 all your tanks.
• 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 (5 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.
