## What is TankLedger?

TankLedger is the private, local-first aquarium log that connects water readings with everything that changed around them.

Instead of scattering tests, maintenance notes, and photos across different places, keep one clear timeline for every aquarium. Record a test in seconds, see values against your own target bands, and understand what happened before and after a change.

WATER TESTS THAT KEEP THEIR CONTEXT
• Build a test panel for each aquarium
• Log several parameters in one quick session
• Review exact values, notes, and timestamps
• Compare readings with keeper-defined target bands
• Follow trends alongside tank events

REPEATABLE AQUARIUM CARE
• Create recurring maintenance tasks
• Track due and overdue work
• Log water changes, dosing, observations, and equipment events
• Keep photos and notes in a chronological timeline

BUILT FOR MORE THAN ONE TANK
• Separate freshwater, planted, reef, quarantine, and other setups
• Keep volume, parameters, care schedules, and history independent
• Move between aquariums from one focused workspace

YOUR RECORDS STAY USEFUL
• Works locally without creating an account
• Export portable CSV data
• Create polished PDF reports
• Delete individual records or all local data from Settings
• Optional Pro iCloud sync uses your private iCloud database

TANKLEDGER PRO
The free tier supports one aquarium, five parameters, three recurring tasks, basic history, and local storage. Pro unlocks unlimited aquariums and panels, advanced trends, PDF reports, widgets, and optional private iCloud sync. Choose monthly, annual, or lifetime access. Monthly includes a seven-day introductory trial when Apple reports that the account is eligible. Subscriptions renew automatically unless canceled through Apple.

TankLedger is a recordkeeping tool. It does not diagnose animals, prescribe treatment, or replace species research, product instructions, or qualified veterinary advice.
