ReefTracker vs Reef Lab

ReefTracker is the offline reef-aquarium logbook built for hobbyists who want real insight into their tank's chemistry - not just a spreadsheet. Log your water tests and instantly see whether each parameter is healthy, borderline, or critical with clear green/amber/red zones. Watch trends over time, catch a slow drift before it becomes a crash, and get an overall tank Health Score at a glance. What you can track - Core parameters: temperature, pH, salinity, alkalinity, calcium, magnesium, nitrate, phosphate, ammonia, nitrite, ORP - 33-element ICP micro-panel for trace elements - import lab reports directly from Fauna Marin or any ZIMS-format export instead of typing every value by hand - Multiple tanks, each with its own parameter set, targets, and history - Water changes, carbon changes, and equipment cleaning logs - Supplement dosing plans and a dose calculator that estimates consumption from your own test history - Key ratios (PO4:NO3, Mg:Ca) and free-ammonia toxicity, computed automatically from your existing readings Read your equipment directly - Hanna checkers: connect over Bluetooth and save each result as it arrives, or point your camera at the display and let the app read the number - ReefFactory meters, Red Sea ReefBeat devices and Neptune Apex controllers (experimental): take probe values straight off the hardware and save them as measurements - All of it on one Connected devices page, over your own Wi-Fi - no cloud service in between Stay on top of maintenance - Reminders for testing, dosing, and recurring maintenance tasks (water changes, filter socks, glass cleaning, and more) - Reverse-osmosis filter stage tracking, so you always know when the next cartridge is due See the big picture - Tank Health Score and Stability Score summarize where you stand and how steady you've been - Trend detection projects when a value is headed out of range, and says so plainly when a parameter is merely swinging rather than guessing a direction - Smart insights surface the handful of things that actually deserve your attention this week Private by design Everything is stored locally on your device. There's no account, no sign-up, and no ads - your data is yours. Connections to aquarium hardware stay on your own network. Back up and restore anytime via the share sheet. Built for fish-only, soft coral, LPS, SPS, and mixed reef setups alike, ReefTracker adapts its default parameters and targets to the kind of tank you run.

Reef Lab is a logbook built for reef tanks — not a freshwater app with a saltwater mode bolted on. Talk to it instead of typing. Ask it instead of searching. Every reading, every dose and every euro that goes into the tank ends up in one place: with charts, totals and an AI that knows your system. VOICE — SAY IT, IT'S LOGGED Tap the mic and talk. Reef Lab works out what you mean and files it where it belongs: • "KH is 8.2" — reading logged • "Salifert calcium, read 6.7 millilitres" — titration reading converted and saved • "Dosed 5 ml of NoPox extra today" — one-off dose on the right pump head • "Head 2 from 4 up to 5 ml" — new daily amount, change kept in the history • "Paused the All-for-Reef" — head paused • "Changed 40 litres of water" — water change logged • "Cleaned the skimmer" — matched to your saved routine • "How much salt do I need for 10 litres?" — handed over to the AI chat When something stays unclear it asks instead of guessing, and every entry can be undone right away. AI THAT KNOWS YOUR TANK • Chat with context: volume, latest readings, livestock, dosing and equipment come along. You get millilitres per day and a safe multi-day plan, not "keep an eye on it". • Tank report: an assessment of the whole system — what is going well, what to watch, what is a real risk, and whether parameters, livestock, light and flow actually fit together. Share it straight out of the app. • Receipt scan: photograph the receipt from the store and the line items land in your inventory with price, shop, currency and date — cross-checked against the receipt total. PARAMETERS, CHARTS & TRENDS KH, calcium, magnesium, nitrate, phosphate, pH and salinity. Salifert users enter the syringe reading — the app does the conversion. • Charts per parameter over 1M, 3M, 1Y or all of it, with min, average, max and latest • All parameters normalised into one chart to see what moves together • Traffic-light rating — optimal, marginal, critical — per entry and at a glance on the tank screen • Zone reference with the target corridor for every parameter DOSING Pump heads with product, element and daily amount. Pause, resume, dose by hand, change the daily rate — every change stays in the history, so you can see when you changed what and how the values answered. CARE & WATER CHANGES Water changes, cleaning, equipment service, filter media, products used, observations. Templates turn recurring jobs into one tap. INVENTORY & WHAT THE TANK REALLY COSTS Fish, corals, inverts, equipment, salt, food, test kits and media — with price, shop, date and currency. • Total cost always on screen: filter the list and the total follows • Filter by category, subcategory, tank, shop and status; sort by name, amount or date • Live counts for fish, corals and inverts — and losses • Several currencies with exchange rates, converted into your display currency DIARY, CALENDAR, NOTES & CALCULATORS Photo diary per coral or animal, a monthly calendar of everything that happened, notes and to-dos. Calculators for salt mix, salinity, parameter correction and daily consumption — the result goes straight to the pump. BUILT FOR REEFERS Softie tank, mixed reef or SPS system: several tanks side by side, offline-first with optional cloud sync, litres or gallons, °C or °F, dark mode, English and German. Free to use, including 5 AI requests a day — chat, voice and receipt scan share that budget. Note: voice input and AI answers are in German for now. Reef Lab does not replace professional advice.
