Aqua Almanac

Keeping an aquarium healthy has never been about gadgets. It is about watching the water, doing the small jobs on time, and noticing changes before they turn into problems. Aqua Almanac is a calm, private logbook for exactly that: track your water tests, plan routine care, keep a full history of every tank, and know what to do next the moment you open the app. EVERY TANK, IN ONE PLACE Create a profile for any freshwater, planted, shrimp or saltwater tank, with volume, start date, substrate, filter and a photo. Everything else in the app hangs off the tank it belongs to. WATER TESTS THAT TELL YOU SOMETHING Record the numbers from your test kit — pH, temperature, ammonia, nitrite, nitrate, GH, KH, TDS and more. Aqua Almanac compares each value against the reference range you set for that tank and marks it OK, low or high, so a wall of numbers becomes a clear answer: is the water safe today? SEE THE STORY BEHIND THE NUMBERS Trend charts draw each parameter over the last week, the last month or the whole history, with your target range shaded behind the line and water changes marked on the timeline. For a new tank, a four-stage nitrogen cycle guide shows how far along the cycling process you are, from the first ammonia spike to a fish-ready home. ROUTINE CARE THAT SCHEDULES ITSELF Log a water change, a filter rinse or a plant trim and the next due date moves forward on its own. Aqua Almanac builds the task list from your real history — overdue, due today, next seven days and later — and can send a reminder on the right day. Tapping a reminder opens the app ready to log the job. A LEDGER FOR LIVING THINGS AND GEAR Keep a record of the fish and shrimp you add, where they came from and how the colony is doing. Track equipment with warranty countdowns and consumable reminders for filter media, bulbs and sponges. SEVEN HANDY CALCULATORS Water change volume, tank volume from its dimensions, salinity from specific gravity, how much salt to mix, hardness conversions, heater wattage, and medication dosing. Every result is a reference estimate — always confirm with a test kit or the product label. PHOTOS WHERE THEY MATTER Attach a photo to a tank, a water test, a maintenance entry, a livestock record or a piece of equipment. Photos are stored inside the app and can be removed at any time. YOUR DATA STAYS YOURS Aqua Almanac works completely offline. There is no account, no sign-in, no analytics and no advertising, and the app never connects to a server. Records and photos alike live inside the app's own folder on your iPhone. Export a clean PDF report whenever you like, or delete everything with one button in Settings. TRY IT BEFORE YOU COMMIT The app starts with a small sample log so you can look around first. Every sample entry is marked SAMPLE and clears out in one tap when you are ready to add your own tanks. Whether you keep a single betta bowl, a dense planted aquascape or a reef full of coral, Aqua Almanac keeps the numbers tidy so you can spend your time enjoying the tank — not managing it.
