TankKeep is getting ready for the App Store. We’ll add the download link here as soon as it’s live.

WHAT YOU CAN FOLLOW

Keep the details together.

01 / WATER

See each reading in context.

Enter the results from your own water tests for freshwater, planted, brackish, saltwater and reef tanks. Review parameter trends against each tank’s target ranges. TankKeep does not measure water or diagnose animal health.

02 / CARE

Remember the care behind the numbers.

Keep water changes, dosing, maintenance, feeding, photos and notes in a timeline for each tank. Reminders for water changes, water tests and maintenance move forward when you log the matching task.

03 / LIVESTOCK

Know what has lived in your tank.

Record additions and removals of fish, shrimp, snails, corals and plants. Review current quantities, each kind’s history and its photos.

A few things you may be wondering.

Can I download TankKeep now?

Not yet. It is coming soon to the App Store for iPhone. We will add the link here when it is available.

Does it test my water automatically?

No. You use your own test equipment and enter the results. TankKeep helps you review those readings over time.

Does it need an account or a connection?

No account is needed. Core recording works offline and keeps records on your device. Export a backup file to keep a copy wherever you choose, such as Files or iCloud Drive.

For the tank you know by heart.

One water test, one water change, one small observation at a time.
