Numday is a 90-second daily mental math challenge for Android. Everyone gets the same 7-calculation chain each day, so scores are easy to compare. Play solo, climb the global ranking, or create private leagues to compete with friends, family, classmates, or coworkers. You can try the challenge without an account; sign in only for rankings and leagues.
