According to EdSurge, only the K-5, SI and Fluency versions of ST Math are available for download as Android and iOS apps. Rather than including written instructions for solving math problems, the software relies on a visual learning approach where the student uses trial-and-error to learn to solve math problems. It is designed as a supplement to math class and may be used at school or at home.
ST Math programs are self-paced and use the student's intuition. Detailed feedback is given so that students see why their solutions were or weren't correct, and teachers can examine reports that show areas in which students need additional help. In addition, ST Math programs focus on common core concepts.
