White Knuckle

AIA solo founder built whiteknuckle.app, a driving app that routes big rigs and campers by difficulty rather than duration. The app warns about grade, tight turns, and clearances based on the rig's height and length, and models turning with truck bed length and hitch dimensions. The founder says the app drew 100 signups in five hours after a post in an RV Facebook group, and that it took about a week to build.

Why it matters: Routes ranked by difficulty, with warnings for grade, tight turns and clearances based on the rig's height, length, bed length and hitch dimensions
