Pricing and Plans
Starter keeps one aquarium organized for free. Tank! Plus is the paid launch plan for expanded capacity and care tools.
Starter
Starter is free and supports one tank. It keeps that aquarium's profile, readings, reminders, and routine care records together.
Tank! Plus
Tank! Plus is the paid plan for the Tank! 1.0 launch. Planned pricing is $0.99 per month or $9.99 per year, with support for unlimited tanks and the Plus feature set shown on the Pricing page.
The Dosing Calculator is implemented and included with Tank! Plus at launch. Tank! Plus is not yet publicly available for purchase.
Built-in and custom Dosing Products
Built-in generic Dosing Product templates are available in Starter and Tank! Plus as local product records. They begin unconfigured and use information that you enter from your own product label.
Creating or editing Custom Dosing Products is a Tank! Plus feature. Custom product notes and warnings, warning-note snapshots, dosing volume modes, and Dose History also belong to Tank! Plus.
Billing and availability
Tank! Plus is not yet publicly purchasable. When purchasing becomes available, Apple will handle billing and subscription management through the user's Apple account.
Exact purchase, cancellation, and subscription-management controls will be documented only after those public flows are available and verified.
