AquaCalculator, like other software, only works on the appropriate devices (desktop computers, notebooks, tablets, smartphones from different manufacturers). So that you can use AquaCalculator on almost any device, we provide 3 different versions.

AquaCalculator, like other software, only works on the appropriate devices (desktop computers, notebooks, tablets, smartphones from different manufacturers). So that you can use AquaCalculator on almost any device, we provide 3 different versions.

a) a version for computers with Microsoft Windows
b) a version for computers, tablets and smartphones with the corresponding Apple operating systems (MacOS, iPadOS, iOS)
c) a version for tablets and smartphones with Android operating system

You can use each version on as many of your own devices as you like. For Apple devices, they must be logged in with the same “Apple ID”. For Android devices, with the same “Google account ID”.

If you want to use AquaCalculator on several different devices (i.e. on different operating systems) or switch from one to another, you must use the appropriate version

There are the following exceptions: You can use Parallels Desktop (for a fee) or other VirtualMachines SW on Apple Mac computers to run the Windows version there.

That depends on which device you want to use AquaCalculator on!

a) For Windows computers: Download the installation program and install it on your computer.

Note: You need admin rights on your computer to do this.

b) For Apple devices: Open the Apple AppStore and search for “Aquacalculator”. Install the app.

c) For Android devices: Open the Google Play Store and search for “Aquacalculator”. Install the app.

AquaCalculator is a paid software. You can only use it with a valid activation/license. The activation/licensing is time-limited. If you want to continue using the program after the license has expired, you must extend your license.
Each “version” of AquaCalculator (Windows | Apple | Android) requires its own license. If you want to use several versions at the same time, you need several valid licenses.

Yes, all three versions offer a time limited and free testing phase with full functionality.

If we could convince you off the huge benefits using AquaCalculator, you simply subscribe to a licensed version of AquaCalculator.
If you do not like to subscribe, please read the answer to “how do i cancel a subscription/licensing?”

The method of activation depends on the device used (operating system on it).

a) Devices with Microsoft Windows: You can either buy or extend the activation/license directly in the program (green bar at the top of the main menu) or via this link.

This version can also be done using so-called “coupon codes” that you receive when you buy a FaunaMarin Balling-Light set (check before buying whether the set you bought also contains this code. Some sets contain a free ICP analysis set instead)

b) Apple devices: Licensing takes place directly on one of your Apple devices in the Apple AppStore.

c) Devices with Android operating system: Licensing takes place directly on one of your Android devices in the Google PlayStore.

This depends on the device used (operating system on it)!

a) Devices with Microsoft Windows: Subscriptions/activations are not automatically renewed when they expire. You do not have to cancel anything.

b) Apple devices: An existing subscription is automatically renewed (this is standard for all Apple apps). You can/must therefore cancel a subscription that is no longer being renewed on one of your Apple devices or on a special Apple website. (Link)

c) Devices with Android operating system: An existing subscription is automatically renewed (this is standard for all Android apps). You can/must therefore cancel a subscription that is no longer being renewed on one of your Android devices or on a special Google website. (Link)

No, unfortunately this is not possible due to the terms and conditions of the different operating system providers and the different app stores.

The revenue from the respective AquaCalculator versions is thus fairly allocated to the three programmers responsible for them.

If you have received a coupon code (e.g. together with a Balling Light Set from our partner Fauna Marin), you can use this to license/activate the Windows version for free.

For reasons beyond our control, we are unfortunately unable to offer this for the Apple and Android versions.

And this is how it works:

1. install AquaCalculator for Windows
2. Open AquaCalculator for Windows
3. After the initial setup, click on the green bar at the top of the main menu.
   Then select “Redeem coupon code” and complete your entries
4. Open your email software and the activation email we will send you within 1 minute
5. Follow the steps in the activation email

Done

Note: Each coupon code can only be redeemed ONCE!

If you have lost your activation data and no longer have it available, e.g. when reinstalling your computer, simply request it again in the program.

1. Open AquaCalculator for Windows
2. Click on the green bar at the top of the main menu
   Select “Resend lost activation code” and complete your entries
3. Open your email software and the activation email that we will send you within 1 minute
