KoiApp — Koi & Pond Tracker

New: log your water tests and let KoiDoctor read them — it weighs pH against KH and nitrite against temperature, and tells you what to actually do.

KoiApp is the complete app for koi keepers and breeders — track every fish, care for your pond, and control it all from your phone. Part of the KoiSoft system.

Built for hobbyists and breeders alike, KoiApp brings your whole koi life into one place.

• Studio ID cards — turn ordinary photos into stunning AI-generated studio portraits, each with its own digital certificate • Growth tracking — log length and weight over time and follow every koi's growth curve • Measure from a photo — mark a known reference and get an exact length without handling the fish • Scan a fish — AI identifies species and variety and estimates size, then carries the fish straight into a KoiDoctor conversation • Water tests — log temperature, pH, ammonia, nitrite, nitrate, KH and GH in under a minute, photograph the test strip, and see every value charted over time • KoiDoctor — ask about health, symptoms and seasonal care, or have it read a water test: it weighs pH against KH, nitrite against temperature and stocking, and tells you what the situation actually is • Feeding — plans that follow water temperature, fish size and the food you use • Breeding — KoiMix weighs a pairing and shows the likely offspring; build a family tree with parents and offspring • Marketplace — discover koi for sale from breeders, or list your own • Ownership transfer — hand a koi to its new owner with the full history: photos, measurements, logs and water tests • Smart hardware — connect KoiBox & KoiPlugg devices to monitor and control pump, UV, heating, lights, feeding and water level
