AquaCalculator is available as subscription since february 2019. To use the AquaCalculator you have to have a valid subscription.
Software is never finished. To finance further development and support, traditional versions are being developed. At regular intervals, new versions appear that offer new features and improvements. Of course, in order to enjoy the features of a new version, it has to be bought and paid for again.
This classic version model is not available on the AquaCalculator. We are constantly integrating new developments and delivering updates and improvements. To finance continuous improvement, support, and our powerful backend aCloud, we’ve chosen a subscription model.
For a very reasonable annual fee you can use the AquaCalculator universe. Of course, you can cancel at any time if you no longer need the services of the AquaCalculator.

You can use any number of macOS devices with your subscription. The only requirement is that they run under the same Apple ID.
No. These are two independently developed products, each of which requires its own subscription at the moment
We do not offer so-called cross-licensing models from AquaCalculator. There are several reasons for this:
AquaCalculator is available in german, english and dutch. For the choosen language in AquaCalculator it depends on your Macs system settings. If any other language is your primary language you might need to adjust your system settings to get AquaCalculator to use your preferred language. You have to set a secondary preferred language to your desired one of one of the supported languages. For example: If the primary language on your Mac is french and you see AquaCalculator in german but would prefer english: Go to your system settings and add english as preferred language after french. Next time you start AquaCalculator it should be in english.
