Aquarily: Aquarium Water Test

Aquarium water test results become an instant green, amber or red status for every tank you keep with Aquarily, an offline water quality log for pH, ammonia, nitrite, nitrate, KH, GH and temperature. Unlimited tanks and unlimited water tests are free. Type each result on one number pad and the color follows your kind of tank as you type. No account, no sign-up, and it works offline. UNLIMITED TANKS AND TESTS As a water parameter tracker, Aquarily holds every aquarium you keep, from a 20 L nano to a 400 L Malawi tank, and lets you log as many water tests as you like. Reef tests are included at no cost: salinity or SG, phosphate, calcium, alkalinity and magnesium. Each tank shows its latest result, when it was last tested and what is due, so the water quality of all your tanks is one glance. Keep a simple livestock list of fish, shrimp and corals for each tank, and a journal of tests and maintenance side by side. TYPE IT AND IT COLOURS Every aquarium water test is colored as you type: the test pad shows each parameter as a cell with a slim three-zone band. Green is OK, amber is Watch, red is Danger, always with an icon and a word, not color alone. A short line says what to do next, for example "Nitrite toxic: change 30 % water, retest tomorrow". Type what your liquid test kit or test strips show; no camera guesses a color. Enter any value, even far outside the range: Aquarily colors it and saves it, it never refuses a number. Skip any test you did not do, or long-press a cell to repeat last week's value. FRESHWATER, SHRIMP, DISCUS, CICHLID, REEF Pick the kind of tank and Aquarily uses general guidance ranges for it: community freshwater, planted, Neocaridina or Caridina shrimp, discus, African cichlid, marine fish-only and reef. A shrimp tank and a Malawi tank need very different KH and pH, so their colors differ too. Your tank, your ranges: edit any limit for any tank, or reset it to the default. ESTIMATED NH3 FROM PH AND TEMPERATURE When you log pH and temperature in the same test, Aquarily shows the estimated free ammonia (NH3), the toxic part, and colors the result by it. For a new tank, the nitrogen cycle card follows your ammonia, nitrite and nitrate tests and tells you which stage it looks like. WATER CHANGE REMINDERS AND RETEST NUDGE Set a water change every 7 days, a filter clean every month, or any task of your own, per tank. Reminders are local notifications that keep working after a restart. Log "Done now" at any time, with the percentage of water you changed. After a red result, Aquarily offers to remind you to retest tomorrow. TANK SIZE AND WATER CHANGE CALCULATORS The aquarium tank size calculator turns inside dimensions into litres and gallons for rectangle, cylinder, bow front and corner tanks, minus substrate and rock. The water change calculator tells you how much water to change to bring nitrate down to your target, in one change or several. Units switch between ppm, dKH and meq/L, SG and ppt, °C and °F, litres and gallons without changing your saved tests. WORKS OFFLINE, NO ACCOUNT, EXPORT CSV Every tank, test and reminder stays on your phone and works without a connection. Export a CSV per tank for any spreadsheet, or back up everything to one file and restore it on a new phone. AQUARILY PRO Logging stays free. Pro adds: - Long-term trends: 90 days, a year or all time, two parameters on one chart, water changes marked, compare two tanks, export PNG. - Dosing calculator: the dose for your tank volume from your own product label, sea salt for a target salinity, and raising KH, calcium, magnesium or GH within a safe daily change. - Unlimited tank photos, a home-screen widget and four extra themes. Pro also removes ads. Choose monthly, yearly, or Lifetime as a one-time purchase; subscriptions renew until canceled in Google Play. Aquarily is a logbook.
