AquaCalculator is available as subscription since february 2019. To use the AquaCalculator you have to have a valid subscription.

why 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.

We do not offer so-called cross-licensing models from AquaCalculator. There are several reasons for this:

  • Contract terms of the AppStores make such models uninteresting or impossible. Remember: Apple, Microsoft, Google & Co want to earn money with the purchases. Cross licenses are therefore a thorn in their side
  • Large programming effort in the applications and server side
  • We work with 3 programmers on 4 different versions. Fair distribution of revenue complicated. You pay fair prices and only for the version you use.
  • Fair for you, fair for us …
