Purchase your Key to Wunderfitz

We ask you only for a small royalty...

Purchase a key after the trial period

Wunderfitz is and will remain Open Source Software. However, in order to support the development of Wunderfitz, we'd like to ask you for a contribution - you could also call it royalty - before you can run it after a trial period of 14 days. Such a contribution can be made by translating Wunderfitz to another language, help developing it or simply by purchasing a key.

As mentioned, you have a testing period of 14 days after the first run of Wunderfitz. Take your time to test the application and ensure that it fulfills your needs and that you really like it. There are no limitations to the software during this time - simply press the button "Continue Testing" on the initial screen.

If you decide to purchase a contribution key in order to keep on using Wunderfitz beyond the testing period, please choose a contribution type. You have the choice between 4 different contributions: S, M, L, XL. No matter which size you choose, the purchased key will unlock the the complete application after the trial period. It's up to you to decide how much the app is worth to you.

IMPORTANT: By purchasing the contribution key, you acknowledge that a refund is not possible as you could already test the software for 14 days!
