Put an end to paperwork! With KoiControl, the tedious recording of water parameters and koi data on paper is a thing of the past. In addition, the built-in food calculator automatically calculates the ideal amount of food for your koi.

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, regular water measurements are part of everyday life. Keep track and store your water parameters in KoiControl. The app analyzes your water parameters and gives you suggestions on how to improve them if necessary. This way you can offer your fish optimal conditions.

Manage and track your koi!
With many koi in the pond, it's easy to lose track. With KoiControl you won't! You can save all important information about your fish, such as name, variety, age, size, weight and much more. Additionally, you can track the growth of your fish exactly and thus make your success measurable.

Determine the ideal amount of food!
How much food do your koi need to grow ideally? Our integrated food calculator provides you with the answer. Based on your koi population and the water temperature, our food calculator automatically calculates the recommended amount of food for your growth ambitions. You don't even need to know the weight of your koi. KoiControl can determine the weight very accurately based on the length of the fish.

Recognize trends early!
As a koi owner, the growth of your fish and the quality of your water are paramount. With our automatically generated charts you can see trends and correlations in your water parameters and the potential of your koi at a glance.
Would you like to share your success with others or record it in a seasonal report? Use the integrated PDF export of your statistics.

Manage your ponds!
All important information such as volume, circulation rate, depth and many more can be stored for a pond.
Do you have several ponds? No problem, fish and water parameters can be clearly assigned to the corresponding pond.

Your data on all of your devices!
You want to use the app on multiple devices? With a KoiControl account you can easily manage your data on all your mobile devices. If you only want to use one device, you can of course use the app without an account and transfer your data at a later time if necessary.

Functional at all times!
No internet connection at the pond? Our koi app can also be used offline.

Seems like a good app.... but the free version is less of a functioning tier and more of a very short-lived demo, in which you need to buy the premium tier to continue. I can understand hiding special features behind a paywall, but when one of those features is "adding information", it's not a free version, it's a demo. The premium tier is also far too expensive for a one-off payment, let alone a repeat subscription.

Just started using the app for my 5 year old Pond, but I already love it. Was able to go back & add different milestones and times koi were added through the years easily. Looking forward to getting a snap shot of parameter changes etc over time. My one suggestion would be to add a "calendar view" option for the pond log. The list is very clean and straight forward, but I sometimes would prefer a more "macro view" of events. That's more a personal preference though & not a negative for the app

Just started using this app and it has everything I need to capture the details of my pond and fish. It seems easy to add and edit pond and fish details. The notes section for pond treatments or individual fish comments is spot on. I look forward to the desktop version so I can see the data in different formats. I don't have enough data in yet to assess the use of the charts but I like the principles.

Calling it a free app is misleading. It has a trial period, when reached you can no longer use 'free app'. Requires buying full version. I was using it to record 'water test' results. I had about 5 recorded. When I went to record number 6, it told me I had reached the limit of free entries. That's when a free app becomes a trial app.

Really liking this app so far! Very clean and easy to use. A bit frustrating that I'll be adding a new koi or parameter log and it will suddenly close the menu, but other than that it works perfectly. I do wish that you could customize the "safe" ranges of water parameters though. I want to be able to see if my parameters are safe within a custom range instead of a preset.

This is a really good app... Apart from one thing only...... Calendar won't display English. You can work it out thought but can take abit getting use too. I paid £9.99 just to test it out for a month before I inform the rest of the Scottish koi club members, just to be the first to try a new koi app. track fish in pond's (you can have more than one in this app and it can do them 1,2 or all) you can record water tests gives you feeding.waa really well pleased about the setup and ease of use.

Really good for tracking progress of pond and koi, great for reminding me of key events or treatments or changes with fish. I will invest in full app

The App is excellent. But I would like it to allow entry of other fish varieties. i.e. Sturgeon, Orfe.
