TankPilot Aquarium Log

Aquarium log for water parameters, reef tanks, water changes, care reminders, widgets, and Shortcuts. Designed for offline use, with a one-time unlock.

TankPilot is the offline-first aquarium keeper for freshwater, saltwater, and reef tanks. No subscription. No ads. Buy once, use forever on iPhone and iPad.

WATER QUALITY LOG Record pH, temperature, KH, nitrate, ammonia, salinity, calcium, magnesium and more. Every reading is stored locally — your data never leaves your device.

TREND CHARTS Simple line charts help you review parameter drift over time. Select any parameter and see how it has changed over time.

MAINTENANCE REMINDERS Add recurring tasks (water changes, filter cleaning, dosing schedules) and get local notifications when they're due. The one-time unlock adds the ability to create new care or inventory records; existing care records and reminders remain available. No account. No server.

TANK & LIVESTOCK INVENTORY Keep a record of fish, corals, invertebrates, plants, and equipment across multiple tanks.

SYSTEM INTEGRATION • Home Screen & Lock Screen widgets show your latest readings at a glance. • Siri & Shortcuts: "Log temperature 26 degrees", "Mark water change done". • Core logging works without Wi-Fi or cellular.

PRIVACY FIRST Data Not Collected. No analytics. No third-party SDKs. The app requires no network permission.

DISCLAIMER TankPilot is a logging and reminder tool only. It does not provide dosing recommendations or professional aquarium advice. Always consult qualified sources for water treatment decisions.
