Manta Math is a beautifully simple Math game that uses timed games to encourage players to memorize their math facts (+, -, x, and /) so that they can go faster. Manta Math adapts as you master questions, showing questions you have not mastered. Manta Math works 100% locally all the time, no internet required. Manta Math does not show in-app ad banners or offer in-app purchases to your kids.
