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.

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. DOSING Plan and track two-part, All-For-Reef, kalkwasser, trace elements, supplements, and custom routines. 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.

Verdict
The clearest difference is rating: Reef Trak at 4.8 against Fishkeeper's 3.0. Reef Trak also leads on update cadence (weekly vs every 5 weeks) and review sentiment (100% vs 85%). Fishkeeper's advantage is in-app purchases (none vs 2) and iOS requirement (15.6 vs 17.0). On price, ads and device support there is nothing between them.
