A calmer way to keep a reef aquarium.
Recif turns your water tests into one number you can trust, tracks what you keep, and reminds you before a parameter drifts. Built for reef keepers who would rather not run a spreadsheet.

Your tank is fine, until it quietly is not.
Reef parameters do not fail loudly. Alkalinity drifts half a point, a test gets skipped for a week, and by the time the corals show it you are weeks behind. Recif watches the trend so you can catch the drift while it is still boring to fix.
One number that means stability.
Every reading rolls into a single 0 to 100 score, so you can tell at a glance whether your tank is holding or starting to wander. Tap it to see exactly which parameter is helping and which is dragging you down.
- How close each parameter sits to its target
- How little everything has been swinging
- How recently you actually tested

History
See the drift before your corals do.
Every parameter is charted over time with your own target range shaded behind it. A line creeping toward the edge of the band is the earliest warning you get, long before anything looks wrong in the tank.
- Your target range shaded on every chart
- Press and hold any point to read the exact value
- Seven days to a full year of history
Keep your reef steady.
