KoiControl - The Koi App

Put an end to paperwork! With KoiControl the annoying process of writing down water parameters and koi data on paper has finally come to an end. Additionally, KoiControl helps you to determine the right amount of food for your koi population.

After downloading the app for free you will first use a trial version with limited functionality. This allows you to get a better impression of the app and, if you like it, you can unlock all features by purchasing the premium version for your account. This is a yearly subscription, which helps us to develop more features for you and enables you to store as many entries as you wish on our servers. Read more below to get an overview of KoiControl's benefits:

Keep an eye on your water parameters! As a pond owner, it is important to regularly measure your water parameters to ensure the well-being of your fish. With KoiControl you always keep an eye on all parameters. The app analyzes your water parameters and gives you suggestions on how to improve them if necessary.

Manage and track your koi! Create your koi as profiles in the app to always keep an overview of your koi population. You can save all important information about your fish, such as name, variety, age, size, weight and much more. The built-in growth history makes it easy to see how well your koi have grown.

Ensure ideal growth! Healthy and strong growth is the desire of every koi keeper. Through our built-in food calculator you can calculate the ideal amount of food. Based on your koi population and the water temperature, the recommended food quantity for your growth ambitions is calculated automatically. You don't even need to know the weight of your fish, as KoiControl determines this very accurately based on the length of the fish.

Recognize developments early! The growth of your fish and the water quality of your pond are very important for you as a koi owner. How nice would it be to see trends and developments in your water measurements and koi growth at an early stage? Thanks to our automatically generated charts you can easily see trends and the potential of your koi. It is also possible to create a PDF file so that you can share your success with others or create a seasonal report.

Manage your ponds! The essential information of your pond can be stored in the app. This includes e.g. volume, circulation rate or the deepest point. Even multiple ponds are not a problem. You can clearly assign fish and water measurements to the respective pond.

Enjoy the app on all your devices! You own more than one device on which you want to use the app? A KoiControl account enables you to manage your stored data on all your devices. Of course, you can also use the app without an account and then transfer your data at a later time.

Can also be used offline! No WiFi at the pond? No problem, our app can of course also be used without an internet connection.
