About
Made for Julian.
Built by his dad over a handful of evenings in 2026, after a Nintendo DS game called Brain Age. Julian was heading into seventh grade and needed his math facts to become automatic.
Will Wallace has spent twenty-five years in public education — math teacher, counselor, and now a high school assistant principal on California's Central Coast.
