Common Questions
Does the app need an account or subscription?
No. It is a one-time-purchase app with no account, advertising, analytics, or in-app purchase.
Does it work offline?
Core features and bundled reference data work on device without a developer-operated service.
Where is my information stored?
Your tank inputs, saved chemistry cases, comparison choices, and display preferences remain in the app's local storage.
How do I remove local data?
Use available delete or reset controls. Removing the app removes its local container, subject to backups you control through Apple.
What are the limits?
Test water with reliable methods and make gradual changes. Calculations do not replace product instructions, livestock observation, or experienced aquarium guidance.
