## What is Aquarist's Notes?

Aquarium health monitoring app.

The Aquarist's Notes allows you to record important water parameters such as temperature, pH, hardness and other factors that affect fish and plant health, add notes and keep a diary. You can add photos from the system photo album directly to the app and add comments or save documents such as aquarium inventory guides. All of this information will be easily accessible and organized right in the app.

The Aquarist's Notes will make calculations related to water treatment easier. 
The app provides accurate calculations of the amount of additives and chemicals you need for proper water treatment in aquariums.

Calculators are available for calculating water volume depending on tank dimensions and amount of decorations, for unit conversions and more.

Reminders and a calendar will simplify your aquarium maintenance planning and you'll never forget anything important again.

Thanks to iCloud, all information can be available on all your devices.
