## What is Aquarium Buddy?

Setting up your first aquarium? Aquarium Buddy is the calm, simple helper that tells you how your tank is doing, without the jargon.

YOUR TANK, AT A GLANCE
A living drawing of your aquarium sits at the top of the app. When every value looks good, the water is clear. When something needs attention, the water turns cloudy and the app tells you what's off in plain words.

A GUIDE THROUGH THE NITROGEN CYCLE
A new tank isn't ready for fish on day one. Aquarium Buddy reads your ammonia, nitrite and nitrate tests and shows which stage of the cycle you're in, with a short note on what to do next. As the cycle moves along, the plants in your tank drawing grow. When it's done, your first fish swims in.

LOG A TEST IN SECONDS
One screen, big number fields, your usual tests already selected. Save a full water test in under 15 seconds. If a value is outside the usual range, you'll see it right away.

CLEAR CHARTS
See how each value changes over time, with the target range shaded behind the line.

REMINDERS THAT KEEP YOU ON TRACK
Weekly water changes, filter cleaning and test days. Mark a task done and the next date is set for you.
