Tanksmith is a logbook for reef aquariums: water parameters over time, livestock and coral records, dosing and maintenance schedules, and the trend charts that tell you a parameter is drifting before the tank does.
It is deliberately offline. No account, no cloud, no forum — your tank log lives on your phone and goes into your device backup like everything else.

FAQ
Is there a subscription?
No. Where an app has a paid tier it is a one-time in-app purchase that unlocks the app permanently, with Family Sharing enabled.
I paid and the app still shows the paywall.
Open the app's settings and tap Restore Purchases. If that does not unlock it, email support with the Apple ID email you purchased with.
How do I move my data to a new phone?
App data is stored on-device and is included in an encrypted iPhone or iCloud device backup. Restoring that backup onto the new phone brings it across.
How do I request a refund?
Refunds are handled by Apple, not by the studio. Go to reportaproblem.apple.com, sign in with your Apple ID, and choose the purchase.
