Your reef tank, trending.
Log your reef tank — water parameters, dosing, livestock and water changes. Reefline works out the trends on your device: how each parameter has drifted, planned dosing versus what you actually dosed, how long since your last water change, and what you've added or lost. Ask for a Tank Recap and the AI turns those numbers into a short, plain-language summary of your log. It describes what you've recorded — it won't give husbandry advice, diagnose livestock, or name a target value. Your log stays on your device; only a small summary is sent to write the recap.
Log it
Record parameters, doses, livestock and water changes as you go.
It finds the trends
Drift, slopes, gaps and cadence — all computed on your device.
Ask for a recap
The AI reads the summary and describes what your log shows.
Does it give husbandry or dosing advice?
No. Reefline describes your own log — drift, gaps, counts and spend. It won't tell you what to dose, diagnose a coral or fish, name a target range, or call a reading good or bad.
Where is my data stored?
On your device. The trend math runs there too; only a small summary is sent to write a recap, and Oriora keeps nothing.
Do I need a subscription?
No. The app is free; you only pay for the AI recaps you run — a fraction of a cent each, billed to your Oriora wallet.
How do I sign in?
With your Oriora account (email code or Google) the first time, then it remembers you.
