Fishify Guardian is an aquarium management and fish-care app developed by AquaTech Solutions, a team of aquarium hobbyists and software engineers. Designed for Android 8.0 and higher, it helps aquarium keepers monitor water conditions, organize care routines, and track fish health across multiple tanks. The app supports freshwater, brackish, and marine environments, with species-specific parameter ranges for more than 300 common aquarium fish.

Users can record pH, ammonia, nitrite, nitrate, temperature, dissolved oxygen, and salinity, either manually or through compatible Bluetooth sensors. Customizable alerts flag readings that move beyond selected thresholds, while historical graphs help reveal changing trends. Fishify Guardian also offers feeding reminders with portion guidance, maintenance logs, water-change calculations, and tools for tracking behavior, symptoms, treatments, and growth. Additional resources include disease information and dosage calculators, compatibility guidance, breeding indicators, and quarantine checklists.

The app can be used offline for logging, with optional cloud syncing for backup and access across devices.
