Gillkeep: Fish Tank Planner

KEEP YOUR FISH HEALTHY WITH CONFIDENCE

A healthy aquarium depends on consistent feeding, water testing, maintenance, and observation. With different food types, fasting days, changing water parameters, and regular equipment care, it can be hard to stay organized. Gillkeep makes aquarium management simple, clear, and stress-free.

Gillkeep is your personal aquarium care companion. It helps fish tank owners manage feeding routines, log water quality, record tank notes, and schedule recurring care reminders—all in one private, offline app.

HOW IT WORKS

Create a weekly feeding schedule from Monday to Sunday. Mark each day as a feeding or fasting day, then add one or more food types to the menu. Choose from built-in options such as Tropical Flakes, Shrimp Pellets, Frozen Bloodworms, and Algae Wafers, or create custom foods with names, descriptions, feeding frequencies, and emoji icons.

When it is time to feed, tap “Log Fed” to save the record. Need to change today’s plan? Use “Edit Menu” to quickly add or remove foods. Gillkeep makes it easy to build a routine that matches the needs of your fish.

Monitor your aquarium with the Water Quality Tracker. Log pH, ammonia, nitrite, nitrate, and temperature, along with notes and automatic timestamps. Clear color-coded indicators show whether each value is safe, requires attention, or is critical. Review your testing history to spot trends, notice changes early, and make confident care decisions.

Use Tank Notes to document important details about your aquarium. Save observations about fish behavior, maintenance work, tank setup, and equipment. Categorize notes as General, Maintenance, Fish Behavior, or Equipment, then filter them whenever you need to find a specific record. Every entry is dated, creating a useful history of your tank over time.

Set recurring Feed & Care Reminders for the routines that matter most. Schedule feeding times, weekly water changes, filter inspections, medication routines, or any custom task. Select the days of the week for each reminder and turn reminders on or off whenever needed.
