This application is not an official SIS client of Charles University. It works by loading the SIS website (version 3) and inserting styles and functions into it so that it is pleasant to use on mobile devices and looks more modern overall.The application does not send any login data or other user data anywhere. The whole application is open-source and you can see its source code on the website https://github.com/sykoram/sis.Some elements and functions may look broken, have their original (old) appearance, or may not work at all - I do not guarantee anything. If you find something like this, or have an idea for another improvement, I will be happy to report it, for example to the email
[email protected], so that I can try to fix or improve it, and thus increase the overall satisfaction of you and others.It is possible that when the sharp version of SIS version 4 is launched, which should also be optimized for mobile devices, this application will be redundant, but for now I find it handy. However, I certainly do not want to discourage you from participating in the trial version of SIS4 - the more people will test it and communicate suggestions for improvement, the better the result will be.I will also mention that there is (at least) another similar app on Google Play: SIS CUNI by Denis HomolĂk, so you can also try it.
