Even though, most trial software products are only time-limited some also have feature limitations. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not.

Trial software allows the user to evaluate the software for a limited amount of time. Demos are usually not time-limited (like Trial software) but the functionality is limited.

In some cases, all the functionality is disabled until the license is purchased. Demoĭemo programs have a limited functionality for free, but charge for an advanced set of features or for the removal of advertisements from the program's interfaces.

Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game.

Record a simulation, then play back at any speed.

Can be installed as a screen saver in Windows.

It records the history of each particle so it can animate and display a path of its travels. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns. It uses Newtonian physics using the Barnes-Hut N-body algorithm. It is released under the GNU General Public License which makes it free. Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X.

Gravit uses the Barnes–Hut algorithm to simulate the n-body problem. The program is available for all major operating systems, including Linux and other Unix-like systems, Microsoft Windows and Mac OS X. Is a free and open-source gravity simulator distributed under the GNU General Public License.
