Awards & Recognition

Selected Articles

  • “Rather than tacking on game-like activities, Ululab hits the elusive edutainment sweet spot. The app is game-like in all the right ways, but also a learning challenge with a clearly defined structure and goals.”
    – Lisa Caplan,
  • “Too much teaching, and the game ceases to keep a child’s attention; too little, and it becomes just another game. That’s one of the reasons Slice Fractions is so great: it has mastered teaching kids about fractional math without having overt lessons to do so.”
    – Nicole Tanner, MacLife
  • “The math concept introductions and level progressions are so well designed that kids will move up the levels smoothly, not even realizing they are learning new concepts or the games are getting harder.”
