## What is Tidal Reef?

Keep your coral thriving. Tidal Reef is the offline-first water chemistry journal built for reef aquarium hobbyists — from first-time reefers cycling their first tank to experienced aquarists dialing in an SPS system.

LOG ALL YOUR PARAMETERS
Track salinity, pH, alkalinity, calcium, magnesium, temperature, nitrate, and phosphate. Log a single reading in seconds, or use the multi-parameter Log Sheet to record your full test session at once.

CHARTS THAT SHOW TRENDS
Interactive charts let you scrub through history and spot exactly where a parameter drifted. Color-coded target range bands mark your ideal zone at a glance — so you can see whether your alkalinity dropped after a water change before your corals tell you.

TRACK WATER CHANGES
Log every water change with volume percentage, date, and notes. A dedicated rolling chart shows change frequency alongside parameter trends so you can correlate maintenance with stability.

HEALTH STATUS AT A GLANCE
The Dashboard shows every parameter with an in-range / low / high indicator. Color-coded summary cards let you run through your water chemistry status in under ten seconds.

OFFLINE FIRST — NO ACCOUNT REQUIRED
Everything lives on your device. No sign-up, no subscription needed to use the core app. Your test results and tank history are yours.

BACKUP AND RESTORE
Export your full history as JSON with one tap and share it anywhere — iCloud Drive, email, AirDrop. Restore from backup just as easily.

REMINDERS
Set a testing reminder so you never skip a check-in. The free tier includes one configurable reminder.

COMING IN PRO
Multi-tank support, custom parameters, CSV and PDF export, and cloud backup are on the roadmap for the Pro tier.

PRIVACY
No analytics. No tracking. No data ever leaves your device.
