Here you can update your old J2ME Algeo calculator. Note that the Java version is no longer developed and it won't receive any update in the future.
In the College edition there are a lot more features then the normal edition, like: differentiate, matrix operations, hyperbolic functions. These are not accessible in the Normal edition. All of the new features are important for any undergraduate students. (Note: this is only for the Java version, you can't upgrade the Android version yet)
You can get the registration key via PayPal.
First download the normal version. Then enter the code in the Upgrade menu in the following box. Check that it's the correct code, otherwise you'll get a bad registration key! We will send you the key in e-mail.
It's only 1.99 €!
