Brinely: Aquarium Manager
Total control of your aquarium
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Log every reef parameter in under 10 seconds. Alkalinity, calcium, nitrate and more — saved privately in your iCloud, never on our servers.
Brinely is the fastest, most private way to track your reef tank. Built for serious reefers who are done with spreadsheets, abandoned apps, and bloated trackers that take 60 seconds to log a single reading.
LOG IN UNDER 10 SECONDS
Tap. Type. Done. Brinely's Quick-Log is the fastest parameter entry on the App Store. Capture alkalinity, calcium, magnesium, nitrate, phosphate, pH, salinity and temperature without fighting your phone.
YOUR DATA STAYS YOURS
Everything syncs through your private iCloud — not our servers. If Brinely disappears tomorrow, your years of readings don't. Export to CSV, JSON or PDF anytime. Zero lock-in, ever.
BUILT FOR REEF, NOT TWEAKED FROM FRESHWATER
• Quick-Log designed for one-handed use at the tank
• Range bands tuned to your tank type (SPS, LPS, Mixed Reef, FOWLR)
• Multiple readings per day — log before AND after a water change
• Pre-loaded maintenance templates per tank type
• Time Sensitive notifications for critical reminders
• Markdown notes with no character limit
LIVESTOCK FOTO-TIMELINE
Watch your Acropora grow over six months with a single swipe. Every coral, fish and invert gets its own photo journal with automatic date stamps — not a static list.
DOSING CALCULATOR
"Alk is 7.8 dKH, I want 8.5, 75-gallon tank, Seachem Reef Builder." Get the dose instantly, with popular two-part and supplement products pre-loaded.
TRENDS THAT ACTUALLY HELP
Beautiful Swift Charts with green/yellow/red range bands. Water-change and dosing markers that don't cover your data. Spot drifts before they kill your livestock.
UNIVERSAL iPad EXPERIENCE
True NavigationSplitView on iPad. Not an iPhone stretched out. Real keyboard shortcuts.
WORKS OFFLINE
Log readings at the tank, in the basement, anywhere. Syncs the moment you're back online.

WHY BRINELY EXISTS
We're tired of paying yearly subscriptions to apps that haven't shipped an update in 18 months. Brinely has a public roadmap and detailed release notes. We answer every email. We built this because we keep reef tanks too.
