Gourami: Aquarium Diary

Gourami is a clean, easy journal for your aquariums. Freshwater, brackish or marine, keep everything about each tank in one place.

• OVERVIEW – see all your tanks at a glance, with a photo, size and how long they have been running, plus a quick summary of inhabitants, last reading and next maintenance.
• PARAMETERS – log temperature, pH, KH, GH, ammonia, nitrite, nitrate, phosphate, conductivity and more, plus salinity, calcium and magnesium for marine tanks. See each value against its ideal range, which you can adjust for every tank, follow the trends over 7 days, 30 days, 6 months or a year, and share a reading as a card.
• MAINTENANCE – schedule water changes, water tests, filter and glass cleaning and water treatments, one-off or recurring, with a full history.
• FEEDING – plan what to feed and when, and keep track of every meal.
• TO DO & CALENDAR – one list with everything due today and in the coming days, filterable by maintenance or feeding, with a calendar view.
• LIGHTING – log your photoperiod (on, off, hours per day) and see how it has changed over the last year.
• CALCULATORS – net tank volume and substrate, water mixing to reach a KH or GH target, remineralizing RO water, and a CO₂ estimate from pH and KH.
• JOURNAL – write notes and add photos to remember how your tank evolves.
• INVENTORY – keep your fish, plants, treatment products, food and equipment in one list, with prices in the currency you paid, and get a warning when supplies are running low.
• YOUR DATA – sync between iPhone and iPad with iCloud, back up and restore from a file, and choose litres or gallons, °C or °F. In English, Italian and German.
• iPHONE & iPAD – designed for both.
