## What is Aquarium Care?

Never forget to care for your aquarium again.

TankMinder is a gentle reminder app for aquarium care. Register tasks like water changes, filter cleaning, water tests, and plant trimming — with photos — and get notified before each one is due, so your water stays healthy and your fish stay happy.

WHO IT'S FOR
- You sometimes forget water changes or filter cleaning
- You keep more than one tank
- You want to keep your fish healthy and thriving
- You're new and want to know "what to do, and when"

KEY FEATURES
Care reminders
Each task gets a recommended cycle automatically. A gentle notification arrives as the due date nears, and keeps reminding you until it's done.

Water quality log & trends
Record pH, temperature, ammonia, nitrite, nitrate, GH and KH. See changes over time on a line chart. Just enter the parameters you measured.

Photo management
Add photos of your fish or tank (the subject is cut out automatically) to recognize each tank at a glance.

Home screen widget
See your next tank to care for, right on your widget.

Aqua tips
A useful, fun aquarium tip every day.

Free to use (up to 3 entries). Go Premium for unlimited entries and an ad-free experience.

Aquarium care, made easier — and more fun.
