Trialware is software designed to stop working after a certain period of time. See also [tag:time-bomb].

Trialware is software designed to stop working after a certain period of time. This is a common feature in shareware applications; the user may use the software for a trial period, and is then asked to either pay for the full version or stop using the trialware. Functionality may be reduced or stopped entirely.

Contrast with a , which stops working on a particular date.
