Common questions
What stays free forever?
Tank tracking, logging, residents, water tests, trend charts, every calculator on this site, Build My Tank, the species library, and the web dashboard. Free is the product, not a trial — Pro adds the AI layer on top.
How do I cancel?
Through your App Store or Google Play subscription settings, like any other subscription. Cancel during the free first month of the annual plan and you pay nothing. Your tanks and history stay yours either way.
Does web Pro cost extra?
No. One subscription covers the app and the web — sign in with the same account and Pro tank analysis works here automatically.
What about refunds?
Purchases go through Apple and Google, so refunds follow their standard store policies. Request one from your store purchase history.
