No. Being a Web Based System you do not need to install anything on your computer. Besides this, the system can be accessed from anywhere, at any time of day, using the Internet.

The Cronos Timetable is new on the market, but, it has many advantages in relation to its competitors. See some of them:
- No installation: To use Cronos, you do not need to install any program on your computer.
-No payment for the System: you do not pay for a system or any kind of license, but only for the schedule generation service.
- Available on the Internet: Cronos can be accessed from anywhere and at any time of day, using the Internet.
-Simple data updates: The data recording is made once and in each year or semester you just have to update them.
- Easy to use: Cronos has the main existing constraints, making the user's life easier when inputing information.

Cronos considers the main constraints in scheduling generations.
- Teachers' schedule conflict: two different teachers cannot be in the same lesson on the same class and same time;
- Teachers' Time off: it is when a teacher cannot be in lesson in a determined time;
- Class' unavailability: it is when a class does not have lesson in a certain time;
- Doubled Lessons: when two or more lessons of the same subject are allocated sequentially;
- Windows: Windows formation (vague schedule) in teacher's timetable;
- Single lessons: classes isolated in the teachers timetable;
- Controls the movement of teachers (in the case of 2 different offices);
- Controls class timing when classes start at different times; etc.
