Store description excerpt

Reefkeel is a reef tank tracker and dosing calculator for saltwater reef-keepers who dose by hand. Log a test, watch your alkalinity, calcium, and magnesium hold the line on a clean trend chart, and get the exact mL/day to dose back to target — before a swing ever reaches your corals. Most reef apps are logbooks: you type the numbers in and they just sit there. Reefkeel is an instrument. It reads your tank's real consumption over time and tells you what to do about it. THE DAILY LOOP • Log a test — alk, cal, mag, NO3, PO4, temp, salinity, pH — in seconds • See it land on the line, against a shaded target band • Catch drift early and get a precise maintenance dose in mL/day CONSUMPTION-RATE DOSING (PRO) Reefkeel computes your tank's actual daily uptake from your logged history and outputs a personalized maintenance dose for the additive you actually use. No black box — it shows the drift it caught and the math behind the number. FREE DOSING CALCULATOR Enter your current value, target, tank volume, and additive — get the mL/day and doses-per-bottle instantly. Free forever. ICP CROSS-TEST TRENDING (PRO) Turn one-off ICP results (Triton, ATI, Oceamo, any lab) into a longitudinal trace-element trend. See which elements are climbing or crashing across every test — not just the latest PDF. INSTRUMENT-GRADE CHARTS Every parameter gets a clean trend line with its target band drawn right on the chart. A swing is obvious the moment it starts — no rainbow spaghetti, no buried tables. BUILT FOR REAL SYSTEMS (PRO) • Multiple tanks, each with its own log, charts, and doses • CSV export of your full test log PRIVATE BY DESIGN No account. No cloud. No tracking. Your logs live on your device and work offline. REEFKEEL PRO Unlock consumption-rate auto-dosing, multiple tanks, ICP cross-test trending, and CSV export — available as a yearly plan or a one-time lifetime purchase. The core loop — logging, charts, and the dosing calculator — is free forever. Keep her steady. Reefkeel is an estimation tool; always verify dosing against your additive's instructions and re-test after adjusting. Not affiliated with any ICP laboratory or additive brand. Reefkeel Pro is offered as an auto-renewing annual subscription or a one-time lifetime purchase. Payment is charged to your Apple ID at confirmation of purchase. The annual subscription automatically renews unless canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. Manage or cancel anytime in Settings > Apple ID > Subscriptions.
