Log and chart your reef aquarium water parameters, on your iPhone.
What it does
Log test results for salinity, alkalinity, calcium, magnesium, nitrate, phosphate, pH, temperature, ammonia and nitrite.
Record water changes and dosing alongside your test history.
Keep a tank diary for the things a number cannot capture.
Set a target range for each parameter and see at a glance what is drifting.
Read trend charts over time for any parameter you track.
Export your data as CSV or as a JSON backup, whenever you want it.
Your data stays on your device
ReefKeeper stores everything locally in the app's own database. There are no
accounts, no analytics and no tracking, and the app makes no network connections of its own.
Nothing is collected by the developer.
