Features

Built for real fish keepers.
No filler.

Tankly is purpose-built for the aquarium hobby. Comprehensive enough for reef obsessives, approachable for beginners setting up their first tank.

Real-Time Tier Health Scoring

Every score is calculated against your tank's exact volume, water type, and livestock mix — not a generic formula. Biological accuracy across four urgency tiers tells you not just how bad a reading is, but how fast it will harm your fish.

Tier 1 hours to harm
Tier 2 days
Tier 3 weeks
Tier 4 optimal

Real-time Parameter Logging

Log pH, ammonia, nitrite, nitrate, temperature, hardness, and more. Visual history graphs surface trends over days, weeks, and months. Spot dangerous spikes before they hurt your fish.

AI Water Insights

Pro users get intelligent recommendations tuned to their specific tank type, livestock mix, and parameter history. Catch problems before they escalate.

Seamless Cloud Sync

Switch phones without losing a single log. Your tanks, history, and settings follow you automatically.
