The app features comprehensive maps that allow you to locate trails with greater confidence than just relying on topographic maps from the National Land Survey of Finland or other mobile apps based on these maps. Many of the trails are also rated according to their difficulty level, such as how rocky, rooty, wet, or otherwise challenging they are, especially for mountain biking.

Trailmap Suomi has received rave reviews from various magazines, including "Trailmap brings trails and route networks to everyone's pocket - Trails on the map!" - Fillari magazine, "Trailmap becomes Finland's trail bank - strong recommendation" - Trail Runner magazine, and "Trailmap knows Finland's trails" - Cycling + Triathlon magazine.
