## Description

ReefVault is the reef log that does the chemistry. Log every water test, dose with confidence, and never lose your tank's history again.

DOSING MATH YOU CAN TRUST
- A target dosing calculator for alkalinity, calcium, and magnesium, built on real stoichiometry and cross-checked against published reef-chemistry references
- A safety rail warns you before a correction exceeds a safe daily change, and explains the pH effect of different products
- Every result reminds you to verify against your own product's label. ReefVault does arithmetic on your numbers; it never prescribes

SEE WHAT ACTUALLY MOVED YOUR NUMBERS
- Trend charts with target-range bands, so you can see at a glance whether you're in range
- Dosing and water-change events plotted right on the chart, so cause and effect are obvious
- Log multiple tests a day, tag each one with the test kit you used, and filter by source

NEVER LOSE YOUR REEF'S HISTORY
- Your data lives on your device and in your own private iCloud. We have no server and cannot see or hold your data hostage
- One-tap CSV export of everything, free forever, whether or not you use ReefVault Pro
- Import from a CSV export from another app to bring your history with you

A REAL RECORD FOR A REAL TANK
- 15+ built-in parameters plus custom ones, each with its own target range
- Livestock, coral, and equipment inventory with photo timelines
- Recurring task schedules for water changes, dosing, filter socks, media changes, and RODI cycles that don't drift when you complete them late
- Manual ICP test entry, always free, plus templated CSV import for ATI and Triton results
- Expense tracking, test-kit timers for running multiple titrations at once, and Home and Lock Screen widgets showing your latest readings and next task

MULTI-TANK, ONE PRODUCT LIBRARY
- Track unlimited tanks (display, frag, quarantine, whatever you run) with a shared product library instead of re-entering the same dosing products for every tank

Logging is free forever: unlimited tests for one tank, all parameters, multiple entries per day, reminders, manual ICP entry, expense tracking, and full CSV export/import. ReefVault Pro unlocks unlimited tanks with a shared product library, the dosing calculator, target-band and event-overlay analytics, widgets, larger photo timelines, test-kit-source filtering, and ICP CSV import templates.

ReefVault is a hobby record-keeper and arithmetic tool. It does not diagnose or treat livestock health and is not a substitute for your own judgment, testing, and research.

ReefVault Pro is an auto-renewable subscription (monthly or annual with a 7-day free trial), or a one-time lifetime purchase. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your App Store account settings. Any unused portion of a free trial is forfeited when you purchase a subscription.
