The Modern AquaticLog Replacement
AquaticLog was a pioneer in aquarium journaling, but if you're looking for something that works great on mobile, offline, and with smarter water trend analysis, MyAquaLog picks up where the old tools left off.
Moving On from AquaticLog?
AquaticLog.com was one of the original online aquarium journals, with over a decade in the hobby and a loyal long-time user base. That track record is a real advantage if you value a tool that has been around and proven stable for years. But the hobby has evolved, today's fishkeepers need a fast mobile app that works offline at the fish store, detects nitrogen cycle issues automatically, and keeps data on your device by default.
MyAquaLog is built for exactly that. Free to start, no account required, and available on every device as a PWA you install straight from your browser.
Pricing Compared
AquaticLog runs about $4.29 per month, or $134.99 for a lifetime plan. MyAquaLog is free to start with one full tank, every parameter, the dosing calculator, and offline use, no account needed. Premium is $4.99 per month, or a $99.99 lifetime option that comes in under AquaticLog's lifetime price.
AquaticLog's longer history may still matter if you specifically want a mature, long-running service. For most day-to-day tracking, MyAquaLog's free tier covers what a lot of people need before ever paying anything.
MyAquaLog Features at a Glance
Built for Modern Fishkeeping
Nitrogen Cycle Detection
MyAquaLog doesn't just record numbers, it interprets them. As you log tests, it detects cycling patterns: ammonia building, nitrite spiking, and nitrate stabilizing. You get contextual guidance through each phase.
Data Stays on Device
Unlike cloud-only tools, MyAquaLog stores your data locally first. No privacy concerns, no account lock-in. Cloud sync is opt-in with a free Supabase backend.
Mobile-First PWA
Add to home screen on iOS or Android, no App Store needed. The interface is built for one-handed use at the tank, not desktop.
Water Change Impact
MyAquaLog correlates your water changes with parameter improvements over time, so you can actually see whether your change schedule is working.
Smart Reminders
Set custom intervals for every task. Get push notifications so you never miss a water change or filter cleaning.
