Michigan Offroad Trail Map 4+

Am I missing something?
How do we know what type of trails we are looking at? Other than MCCT in the name, there seems to be no reason to the names or colors of the icons (that I can quickly determine) Example; North Branch Route or North Branch Route Track. What are they, motorcycle only, orv, side by side? What is a track? That is not verbiage that the DNR uses.
I like to ride motorcycle only trails, how do I determine this? Which trails require a motorcycle to have a license plate?
Example: Both Horseshoe Lake Trails have a red icon, doesn’t the north loop require a license plate?
Or how does a side by side driver determine which trails he can access?
I think I purchased this too quickly and, unless I’m just missing the details - which I could be, I don’t think this will be any use to me.

Am I missing something? Omit says it’s compatible with my iPhone but doesn’t show any trails and the search function doesn’t do anything

The trails aren’t labeled very good when riding but using this app with gps is great because it shows your location on the map. It was well worth the $3 to get around here on the upper Peninsula! When you download it I recommend downloading ALL of the trails the four wheeler and the snowmobile trails you can get anywhere you want the area is covered in trails. We took an atv from paradise the whole way across!
