Trail Router, a free Android app, is designed to help runners find new routes. Developed by Trail Router, this app is available in the Lifestyle category under the Sports subcategory.

With Trail Router, runners can automatically plot a round-trip route of a desired distance or manually create their own point-to-point route that prefers greenery and water. The app's routing algorithm prefers paths that go through parks, forests, or by water, and avoids busy roads wherever possible.

Additionally, users can choose whether they would prefer routes that involve nature, well-lit streets, or a lack of hills. Overall, Trail Router is an excellent app for those who want to explore new running routes and enjoy nature while staying fit.
