Track water parameters, plan dosing, schedule maintenance, manage livestock, save photos, build PAR maps, import controller data, track expenses, and create reports across iOS and the web. Build a complete reef care history, then export real tank data to AI tools with TrakAI. FREE TO START. ONE-TIME PREMIUM UPGRADE. Reef Trak includes a free version with parameter tracking and core reef tank tools. Reef Trak Premium is available as a one-time upgrade. No monthly subscription. No yearly subscription. Pay once and use Premium tools without another recurring app bill. PARAMETERS Track alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature, pH, ORP, iodine, potassium, trace elements, and other reef tank parameters. Follow trends, spot drift, review stability, and see clear in-range or out-of-range indicators.

Use manual and guided dosing tools, bottle tracking, dose logging, reminders, and parameter connections to keep dosing tied to your real tank history. MAINTENANCE Create recurring tasks for water changes, filter swaps, probe calibration, dosing reminders, equipment checks, deep cleans, and custom care routines. Use weekly, fortnightly, monthly, yearly, every N days, or specific weekday schedules. Home screen widgets help show what is due today. LIVESTOCK Catalog fish, coral, and inverts with photos, care notes, acquisition history, tank placement, and long-term records. PAR MAPS Capture PAR readings across your reef tank and map them visually to understand coral placement, lighting coverage, and tank zones. TRAKTONE PHOTO & VIDEO CORRECTION Reef lighting can make photos and videos look far more blue than they appear in person. TrakTone helps correct reef tank photos and videos so corals, fish, and aquascapes look closer to what your eyes see. EQUIPMENT, EXPENSES & RECEIPTS Track equipment, food, dosing products, livestock purchases, maintenance costs, and other reef expenses.

Most new reef-keepers quit in their first year — usually somewhere in the "ugly stage," when algae blooms, parameters swing, and every forum answer disagrees. Reefr exists to walk you through that valley. Reefr is a first-year reef companion that learns YOUR tank — not generic advice, but early warnings drawn from your own history. LOG IN SECONDS Track the vitals that matter — temperature, salinity, alkalinity, pH, nutrients — with fast, friendly logging. Works fully offline; syncs when you're back. EARLY WARNINGS FROM YOUR OWN TRENDS Stability beats perfect numbers. Reefr watches your history for the swings that actually harm livestock and flags them gently — calm and clear, never panic. MEET NEMO Nemo is a calm clownfish companion who knows your tank's whole story — every reading, every photo, every past wobble. Ask anything in plain language and get one conservative next step. Never a wall of options. GROWS WITH YOUR TANK A new tank starts simple. Features unlock as your reef matures and you're ready — through cycling, the ugly stage, stabilising, and thriving. YOUR PHOTO CATALOGUE Snap your fish, corals and gear; Nemo can identify species from your photos — only when you ask. Watch your reef's story build over time. LEARN AS YOU GO Short, vetted articles surface exactly when they're relevant to what your tank is doing — not a firehose of content. PRIVATE BY DESIGN Your readings, photos and notes live in your private account — never sold, never used for ads, never mixed into analytics. AI sees your data only when you explicitly ask. Also on the web: sign in to the Reefr web companion for big-screen trends, bulk logging and your full history. Reefr is free while in early access. Your tank, remembered
