## What is Aquarium Harmony?

Aquarium Harmony is the calm, beautiful way to keep every fish tank thriving. Log water tests, build a care routine with smart reminders, and watch your aquarium come alive as a living, breathing picture of its real health - on iPhone, Apple Watch, and your home screen.

Whether you keep a planted tank, a reef, a betta, shrimp, cichlids, or a classic freshwater community, Aquarium Harmony turns scattered notes and guesswork into one clear answer: what does my aquarium need today?

A LIVING AQUARIUM, NOT A SPREADSHEET
Every tank gets its own living world - water that brightens with good care and dims when maintenance slips. Three health rings show Care, Water, and Stability at a glance, with a full breakdown explaining every factor behind them.

WATER TESTING MADE SIMPLE
• Log pH, ammonia, nitrite, nitrate, temperature, GH, KH, TDS - plus salinity, alkalinity, calcium, magnesium, and phosphate for marine and reef tanks
• Clear trend charts with safe ranges for your exact setup
• Spot drift early: rising nitrate, falling KH, temperature swings
• Stability tracking shows which parameters hold steady and which wander

SMART CARE REMINDERS
• Water changes, filter maintenance, plant trimming, dosing, equipment checks - on your schedule
• Feeding schedules with portions, so everyone in the family knows who fed the fish
• One "Next up" priority every day: never wonder what matters most
• Complete care from your wrist with the Apple Watch app

KNOWS YOUR FISH
A built-in species guide with 70+ popular fish, shrimp, snails, corals, and plants. Aquarium Harmony reads your real stock: preferred water ranges, group-size suggestions, and compatibility notes - turned into friendly insights, not alarms.

YOUR AQUARIUM'S MEMORY
• A unified timeline of every test, water change, milestone, and photo
• Take photos in the app and watch your aquascape evolve
• Day counters, care streaks, and milestones celebrate the relationship you're building

APPLE WATCH, WIDGETS & COMPLICATIONS
• Full watch app: today's care, health rings, and one-tap task completion
• Home-screen widgets for one tank or your whole fishroom
• Watch-face complications and Smart Stack support

SHARE & BACK UP
Export any aquarium as a compact encrypted file - share your setup with friends or move it to a new device in seconds.

FREE & PREMIUM
Aquarium Harmony is free for one aquarium with core care tools. Premium unlocks unlimited aquariums, deeper analytics (forecasts, correlations, full health breakdowns), your complete history, weekly reports - and removes ads. Subscriptions renew automatically until cancelled; a one-time lifetime purchase is also available. Prices are shown in the app before any purchase.

PRIVATE BY DESIGN
No account required. Your data lives on your device - export it anytime.

Whether you're cycling your first 10-gallon tank or managing a fishroom full of aquariums, Aquarium Harmony gives your underwater world the calm, consistent care it deserves.
