## What is Reefline Log?

Reefline Log is the focused water-test log for reef keepers who want quick entry and clear history without an all-in-one aquarium platform.

LOG IN SECONDS

• Enter a batch of readings in one place.
• Previous values are ready when your test context loads, so unchanged numbers take less work.
• Skip any parameter, change the test date and time, and add one short note.

TRACK WHAT MATTERS

• Record alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature, and pH.
• Add custom numeric metrics for the other measurements you care about.
• Choose the units that match your test kit, with visible conversions where supported.
• Set optional personal low and high target bands. Reefline shows your bands; it never tells you what a value should be.

SEE YOUR HISTORY

• See the latest readings and time since your last test on the dashboard.
• Open charts for each metric across 7-day, 30-day, 90-day, or all-time views.
• Review, edit, or delete saved test sessions.

KEEP YOUR TANKS ORGANIZED

• Track multiple tanks and keep each tank's readings, metrics, charts, and reminders together.
• Create local recurring reminders for water tests or dosing.

OWN YOUR DATA

• Works offline with local storage on your iPhone.
• Optionally sync through your private iCloud database.
• Import a Reefline CSV or export your readings whenever you want.

Reefline Log has no account, subscription, advertising, tracking, or AI recommendations. Every feature is included in one purchase, and your target bands remain your own.
