nagware (jargon) /nag'weir/ A term, originally from Usenet, for the variety of shareware that displays a message on start-up and/or termination reminding you to register, pay or donate (see guiltware).
Sometimes user interaction is required to dismiss the nag in order to use the program, making it useless in batch mode. Nagware may also be crippleware, with a message nagging you pay to upgrade to the full or "pro" version. [Jargon File] Last updated: 2015-01-17
