About

FishDiary

Read full description

FishDiary is a quiet log book for aquarium keepers. Write down what you did to each tank and the water values you measured, then look back at how things changed. FishDiary keeps records. It does not decide anything for you: no scores, no verdicts, no advice. What you write is what you get back. WATER VALUES, DRAWN AS A LINE Save pH, GH, KH, NO3, NO2, NH3, PO4, Ca, Mg, temperature and salinity, each with the unit you actually use. Every tank gets its own chart, so a slow drift over several weeks is easy to notice. If a value you follow is not on the list, add your own. TODAY'S RECORD IN A FEW TAPS Log water changes, feeding, algae removal, dosing, equipment care, water tests and anything else. Add a date, a note and photos. You can define your own work types, and record the same work for several tanks at once. RECORDS AND PLANS ON ONE CALENDAR What you have done and what is coming up sit on the same calendar. Set repeating plans for weekly or monthly work. If you want a nudge, switch on a daily summary or a water change notification and pick the time yourself. YOUR TANKS, YOUR WAY Add as many tanks as you like, freshwater or marine, with photos, tags and the details you care about. Search across every tank and record when you need to find something. Archive a tank when it is closed down, and bring it back whenever you want. FREE AND PRO The whole app is usable for free, with a small banner at the bottom of three screens. On the free plan you can create up to three custom water parameters, custom work types, repeating plans and tags, and attach up to three photos per entry. Pro removes the banner and those limits, and adds export: - CSV of your tank list, care history, care summary or water values - PDF report for a single tank, or for your whole collection Pro comes as a monthly or yearly plan, or as a one-time Lifetime purchase with no renewal. A FEW MORE THINGS - Your records stay on your device. No account, no sign-in. - Backup and restore, so moving to a new phone keeps your history. - Light and dark appearance, or follow your system setting. - Available in 19 languages.
