ReefBot — Reef Aquarium AI
Coral diagnosis & dosing log
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
NEW in 1.1.0: comments + push notifications on community posts. Plus optional gear details (lighting, skimmer, flow, controller) that follow your photo when you share.
Diagnose coral problems from a photo. Log a full reef-aquarium water test in 30 seconds. Tune your dosing from your tank's real consumption rate. Built native for iOS by reef-keepers, for reef-keepers.
Snap a photo of your tank, and the built-in AI photo diagnosis tells you what's likely going on — cyano vs. dinos vs. brown jelly vs. healthy slime — with a confidence score, not a guess. Every diagnosis is grounded in your most recent water parameters (alkalinity, calcium, magnesium, NO3, PO4) so the suggestion already accounts for whether your alkalinity is dropping.
Log a full weekly water test in 30 seconds. The Test Session wizard walks you through Alk, Ca, Mg, NO3, PO4, salinity and temperature one at a time, pre-fills your last value, shows the healthy zone, and saves the lot in one go.
The Today briefing on every tank dashboard surfaces the four things that actually need you right now: parameters drifting outside the safe band, maintenance overdue by N days, water tests you haven't run in a while, and consumption rates that have started to creep. One tap takes you to the right action.
The Suggested Dose card calibrates from your test + dose history. After every fresh reading the math reconciles "what we expected to add" against "what the tank actually consumed" — so each recommendation uses your tank's real demand, not a generic BRS formula. Run Tropic Marin Carbocalc instead of BRS Pt 2? Pick it in Dosing recipes and the calibration adapts. Or roll your own custom mix with a measured coefficient.
Insights computes real consumption rates per parameter ("Alk being consumed at 0.3 dKH/day over the last 14 days") so you can tune dosing on rate, not raw values. Reefers know this is the metric that actually matters.
Multi-tank support, photo timelines, maintenance reminders that respect your schedule (no nag spam), full JSON + CSV export so your data is yours. Community feed for sharing tank shots — no account, no email, no signup.
ReefBot Pro — $4.99/month, 7-day free trial.
After trial: full access to AI photo diagnosis, calibrated dose suggestions, multi-tank support, complete data export, and proactive Insights.
