Featured Product
Benster
Designed for focused practice
Short, timed practice sessions help learners work on individual math skills or mix them together, with multiple ways to answer and progress at their own pace.
Math practice that feels fun and approachable.
Benster is a playful math-practice app that helps kids build confidence with addition, subtraction, multiplication, and division. Short, timed sprints keep practice focused while a friendly penguin mascot and colorful design make learning more engaging.
Learners can review incorrect answers, track personal bests, and build practice streaks as they improve. Benster works on iPhone and iPad, requires no account, and keeps nicknames and practice progress stored locally on the device.
