Log every test in seconds and see each value at a glance. One-time purchase - no subscription, no ads, no account. Everything stays private on your device.
TankVitals is the clean, no-nonsense way to track your water and keep your fish and corals thriving. Whether you run a planted freshwater tank or a full-blown reef, enter your test results and instantly see every value color-coded by safe range - green when healthy, amber when drifting, red when it needs attention.
Know Your Water at a Glance
The moment you save a test, each parameter is scored against community-standard safe ranges and color-coded so you know exactly what needs action. No more digging through charts to interpret a number.
Log a Test in Seconds
A focused entry screen pre-fills the full parameter set for your tank type, with a safe-range bar under every field. Back-date readings, add notes, and your history merges automatically by day.
See the Trend Over Time
Tap any parameter to open its history as a chart or a full list. Watch alkalinity, calcium, or nitrate move over 30, 90, or all-time days, with the safe range shaded right on the graph.
