## What is Aquarium Harmony?

Aquarium Harmony is a calm aquarium care log for every tank you keep. Log water tests, get reminders for water changes and maintenance, and see at a glance how healthy your aquarium is. The home screen is a living, animated aquarium that matches your tank type and reflects how well it is cared for.

WHY AQUARIUM HARMONY
• Know what needs attention today, without digging through notes
• Keep water parameters stable and catch problems early
• Never forget a water change, filter clean, feeding or water test
• Remember every fish, shrimp, snail, plant and coral in your tank
• Watch your aquarium improve over weeks and months

WATER TESTS AND WATER PARAMETERS
• Log temperature, pH, ammonia, nitrite, nitrate, GH, KH, TDS, phosphate, salinity, alkalinity, calcium, magnesium and more
• Each tank gets the parameters that matter for its type
• Every value is checked against its preferred range, with a clear warning when it drifts out
• Charts show the history and trend of each parameter, and readings outside the range stand out in red or blue
• Units you know: °C or °F, liters or gallons

AQUARIUM HEALTH SCORE
• Three health rings for care, water and stability, with the reasons behind each one
• Status at a glance: good, needs attention or action needed
• Care streaks, days together and milestones

CARE REMINDERS AND FEEDING
• A suggested care routine for your tank type, ready in one tap
• Recurring tasks for water changes, water tests, filter maintenance, glass cleaning, plant trimming, dosing, medication or anything you add yourself
• Feeding schedules with portions, so everyone at home knows who fed the fish
• Reminders arrive when a task is due, with a Done button right in the notification. No spam, only your schedule

INHABITANTS AND SPECIES GUIDE
• Add fish, shrimp, snails, plants and corals to each aquarium
• 74 built-in species with preferred water ranges, care difficulty, temperament and group size
• See which water ranges your inhabitants share before you add new livestock
• Add your own species when something is not on the list

SMART INSIGHTS
• Spots trends in your water, like rising nitrate, before they turn into problems
• Shows what your last water change did to your values
• Early warnings, links between parameters and forecasts with Premium

TIMELINE, PHOTOS AND SHARING
• A timeline of every test, water change, milestone and photo
• Take photos in the app and watch your aquascape grow
• Export an aquarium as a file and share it with a friend, or move it to a new phone

APPLE WATCH, WIDGETS AND COMPLICATIONS
• Apple Watch app: today's care, health rings and one-tap task completion
• Home Screen widgets for one tank or your whole fish room
• Watch face complications and Smart Stack
