About this app
Your test results are scattered. ReefDrift fixes that.
You test 1–3 times a week. Alk goes in Notes, calcium in a spreadsheet, pH you swear you'll remember. By the time you spot a drift, your SPS is stressed and your frag tank is showing it.
ReefDrift is a fast, offline-first reef parameter logger that tells you whether your tank is stable — the moment you save a test.
Free. No account. No cloud. No subscription.
LOG THE BIG THREE AND EVERYTHING ELSE
Alkalinity (dKH), Calcium, Magnesium — the parameters serious reefers obsess over. Plus Nitrate, Phosphate, pH, Salinity, Temperature, Ammonia, and Nitrite.
Last values pre-fill automatically. A full test set takes under 10 seconds.
TANK STABILITY SCORE
ReefDrift calculates a Stable / Watch / Danger score the instant you save a reading. 0.3 dKH drift shows up on your dashboard before you wonder why a frag is pale.
