## What is Aquarium Care Tracker?

Track every parameter that keeps a tank healthy — pH, ammonia, nitrites, nitrates, temperature, GH, KH, TDS, salinity, plus one custom parameter — logged in seconds.

See up to three parameters overlaid on one chart, with every water change, feeding, and maintenance event marked right on the curve. Cause and effect, side by side — no switching screens, no single-parameter view to work around. The multi-parameter chart is part of the unlock.

Danio keeps water tests, water changes, feeding, and every new fish or plant on one timeline, so nothing gets lost between visits.

The Stock page shows what is actually in the tank right now. Log a fish or plant leaving, not only arriving, so the count stops drifting from reality.

Set reminders for water changes, feedings, and filter maintenance. Notifications arrive on schedule, even after the app has been closed. Reminders are part of the unlock.

Add a photo of the tank. Watch trends develop over weeks and months instead of guessing from memory.

Export a full backup anytime — free, no purchase required. A JSON file to import back on a new device or after a reinstall, plus a CSV of every measurement for your own spreadsheet.

One tank is free, always. The unlock covers unlimited tanks, the multi-parameter chart, and reminders — as a one-time lifetime purchase or a subscription. A subscription is never forced, and Family Sharing works on every plan.

Every measurement stays on this device. No account, no server, no ad tracking.
