Help & support ↗
Will it be free?

The planned Android release includes free water change records, history, reminders and backups, with a banner below the tank list. An ad removal purchase is in preparation and is not available for sale yet.

Are my tank records sent to the developer?

Tank records stay on your device. The app has no feature to send them to a developer server. The ad SDK handles information for advertising and related purposes. See the privacy policy for details.

Can I move to another phone?

Export a backup first, then restore it on the new phone. There is no automatic cloud sync. Keep a backup before uninstalling the app as well.

Does it support Japanese and English?

A bilingual build is in development, with the initial language based on your device and an in-app language selector. Your own tank names and notes are kept as entered.

Does it choose when my tank needs a water change?

You choose the interval to suit your tank. AquaNote does not measure water quality or decide when a change is needed. Device settings may delay notification delivery.
