About

Nitrify

Features
Read full description

Your test kit gives you numbers. Nitrify tells you what they mean. Log ammonia, nitrite and nitrate, and Nitrify reads where your tank is in the cycle, whether the water's safe, and what's changed since last time. Made for freshwater keepers who want an answer, not just a spreadsheet. Know your cycle. Every test gets a stage: waiting on ammonia, the nitrite spike, finishing, or fully cycled. Pro reads your own trend to estimate when it'll finish. Know if it's safe. A plain Safe, Watch or Act call on every reading. Pro breaks down ammonia, nitrite, nitrate, pH, GH, KH and phosphate against their target ranges, and warns you when one drifts the wrong way. Stay on top of upkeep. Water changes, filter cleans, plant trims and dosing, all in one log. Pro adds reminders, custom schedules, and a dilution preview that shows what a 30% change does to your nitrate. Your tanks, your data. Multiple tanks with Pro, a photo journal, a Home-Screen widget and CSV export, all synced over iCloud with no account and nothing sent to a server. Full light and dark mode. Pay once. Free covers logging, your cycle stage, the safety verdict, one tank and iCloud sync. Nitrify Pro is a single one-time unlock. No subscription, no ads. Nitrify reads your water against general freshwater ranges to guide you; it isn't a diagnosis of your tank or livestock. During a cycle, high ammonia and nitrite are normal, and the app tells you so.
