## What is KoiLog?

Record each koi's growth as a living asset — a keeping journal for serious nishikigoi keepers.

■ Koi detail (the hero)
Open a koi and its whole history rises like a hanging scroll: overhead photos and a length growth curve by year, body / skin / pattern ratings, and acquisition date, price and bloodline.

■ Health & treatment log
Record symptoms, treatment, dose, quarantine and outcome — so you can look back on the whole course when it matters.

■ Pond water
Log temperature, pH, KH, GH, ammonia, nitrite, nitrate and salt, with a calm warning when a reading is out of range.

■ PDF / CSV export
For a show entry, or to hand to the next keeper. Your records are always yours.

• Fully offline — data stays on your device
• No ads
• For recording and visualising only (not medical advice).
