A calmer daily flow

From “what is due?” to a record you can keep.

01

Today

See due and overdue care for the selected tank. Complete, snooze or skip an item, or start a quick test.

02

Tests

Record common or custom numeric parameters, then view each parameter's history as a neutral trend.

03

Care

Schedule user-titled recurring work with your own interval, then keep completed, snoozed, skipped and reopened actions in History.

04

Inventory

Keep livestock, plant and equipment dates and notes with clear category-specific lifecycle states.

Built around your records

Unlimited tanks. Separate exports. One complete backup.

Profiles that fit. Freshwater, planted, brackish, saltwater and reef, in litres or US gallons.

History you can work with. Search combined history, edit tank or inventory details and undo supported destructive changes.

Portable by choice. Export tests, maintenance and livestock as separate CSV files, or create a JSON backup for restore.

Accessible by design. Scalable text, screen-reader labels, strong contrast and reduced-motion support.

A clear boundary

TankTide records. It does not prescribe.

TankTide has no preset safe ranges, aquarium-health score, diagnosis, treatment, dosing, stocking or compatibility advice. If you add a target band, it is your own reference and the app does not verify or interpret it.
