MatFikhos: Aquarium Keeper's Kit is a complete offline logbook, calculator lab and learning companion for freshwater, planted, brackish and marine reef tanks. Log every tank with its shape, size, real water volume and photo, then add fish, shrimp, plants and corals from a built-in species library that warns you about water type, temperature, tank size and tank-mate clashes. Record water tests for temperature, pH, ammonia, nitrite, nitrate, GH and KH, see each reading against the safe range for your water type, and follow trends on clear charts. Keep a care timeline of water changes, filter cleaning, trimming and dosing, while a "Needs a look" list shows which tank is due for a test or water change. Three detailed calculators work out real water volume, stand weight and stocking level, the water change size needed to reach your nitrate goal with a four-week plan and doses, and the heater, filter flow, lighting and monthly running cost for your setup; save, share and reopen any result. Learn the hobby with species care sheets, flashcards, three quiz modes and badges, and use the built-in spirit level and tilt meter to set your tank stand perfectly level. No account, no internet and no notifications: everything stays on your iPhone.
