About
NeerBoolsF is a one-stroke trail studio for iPhone. Cover every edge exactly once with a continuous path. Browse Spark to Summit atlases, play Daily Trail, build graphs in Workshop, study parity tips, and track clears from a hub with no tab bar. Undo, reset, and hints aid practice on iOS 15 and iPhone SE. No camera or storefront — just trail craft.
