- Included in that plan direction.
- Not included.
- Planned or future-facing only.
- Ad-free is a paid-plan benefit direction for when ads and paid plans exist; it is not a separate one-time purchase.
- Tank! Journalist, Algae Watch, and photo-memory features are not live.
- Billing, StoreKit purchase, restore, and subscription fulfillment are not active yet.
Planned does not mean live
Tank! Plus billing, Tank! Journalist, Lighting tools, and Algae Watch should be read as pricing and feature direction until an app version explicitly makes them available. Ad-free is a plan benefit direction, not a separate purchase. Tank! features are for recordkeeping and routine awareness, not diagnosis, treatment, chemical recommendations, or safety guarantees.
