You race yourself
Every run you finish is saved as a Ghost Rider — a record of how fast you answered each fact. Then you race them. The opponents aren't strangers or invented characters; they're you, last week. Getting faster is the whole game, and you can watch it happen.
Seven ways to play
- PracticeWork through the facts at your own pace. Answer fast and the square turns blue or purple; take a while and it goes orange or red.
- TrainingTargets the facts you found trickiest last time, instead of making you grind the ones you already know.
- Horse RaceLine up against the Ghost Riders of your past runs. The field grows as your history does, and riders you outgrow retire to the Hall of Fame.
- SurvivalThree hearts. A wrong answer or a timeout costs one. A long enough streak earns one back.
- CompareTwo problems side by side — tap the bigger answer. Builds a feel for the size of numbers, not just recall.
- PatternsFind the number missing from a sequence. 24, 32, __, 48.
- Daily ChallengeA fresh set every day. Miss a day and your streak is forgiven once — but you have to earn that back.
Play together
Duel puts two devices head to head over a local connection. No internet, no accounts, no servers — the devices talk directly to each other.
For parents and teachers
Classroom Mode lets a teacher send a problem set to student devices and collect the results back, again over a local connection with nothing leaving the room.
The Progress Report shows which of the 429 math facts a child has actually become fluent in, per operation, so practice can go where it's needed.
Reward goals let you set a target together — ten runs, a streak of twenty — and the app prints a certificate when it's met.
Running a class? Evaluations, progress over time and per-student proficiency all live in the companion app — more about MathDash Teacher →
