for your feedback as well!

After many days of hard work and testing geocubes is now finally available on our website. Until the 28th of February geocubes is free with unlimited points. Please feel free to sign-up and test our service. We will work hard on new features in the next weeks. If you have any ideas for new geocubes features please contact us.

We are looking forward to your feedback!
