Basically, you can also use the RedCrab Calculator as a freeware without registration. However, you will have to forego the benefits listed above.

The activation of the full version is effective for 24 hours. After the time has elapsed, a new activation code can be requested here.
   

Why only 24 hours?

  1. Has it happened to you that you have activated the trial mode of a new software to get a first impression, but then had no time or no suitable project for a detailed test? If you have time or a project, the trial period is expired.

    That can not happen to you at RedCrab anymore! You can request an activation code on a daily basis if you need one. Until further notice the number of activations is not limited.

  2. Users who only rarely need a math software and therefore the purchase is uneconomical, can now access the full range of functions when needed.

  3. The RedCrab Calculator is used worldwide. Including in countries where a monthly salary is barely above or even below $ 100. These people with an extremely low income can now gain access to the full version features of RedCrab.

Why buy a RedCrab PLUS license?

  1. An annual license for RedCrab costs just over $ 1 per month. If you use RedCrab frequently and your hourly wage is well over $ 1, buying a license is more economical than repetitive activations.

  2. By buying a license you show the appreciation for our product and support our future developments.
