Trapster has announced that it is shutting down by the end of the year after unpublishing its mobile apps earlier this week. Once boasting as many as 20 million users, the service alerted users to nearby speed traps, DUI checkpoints or road hazards by leveraging crowdsourced information.

The service was acquired by Nokia in 2010, but failed to provide any significant updates as competing services like Waze started seeing more traction. In an email sent out to users, the team at Trapster had this to say:

"After evaluating our ongoing investments, we have decided to discontinue the Trapster service by the end of the year."

"It is hard to imagine saying goodbye after 7 years but we want to thank you for using Trapster and your loyalty to the Trapster community."

"Thank you, Team Trapster"

The exact reason for the discontinuation of the service is unknown, and we'll share additional details as we get them. At this stage, it is not known whether the service's technology will be incorporated into Nokia's Here navigation solution.
