This paper describes the design and development of a mobile service to make practical assessments of different topics of mathematics in order to improve the skills of students in high school education. This tool has the ability to create user accounts for participants, as well as storing statistics about their practices with the purpose of giving students feedback of the subjects evaluated. The mobile application was developed natively for the Android platform because of the advantages offered by this technology such as access to platform resources in a straightforward manner, coupled with benefits provided by current complementary tools such as PHP, JSON, MySQL and WiFi wireless technology.
