JXCirrus Maths is a maths training application aimed at primary school children.   It focuses on basic arithmetic: Times tables, addition, subtraction and division.  It will let you set up exercises that are run each day, and then records the best time and lets you race against that.



  • Set up any number of exercises for your child.

  • Times tables and division: Select one or more times tables to practice, choose how many questions will be asked, choose whether they will be run in random order.

  • Addition and subtraction: Select a range to add up to or subtract from (i.e. add up to numbers between 15 and 25) and how many questions to be asked.

  • Schedule exercises to be run once a session, once a day or once a week.

  • Records the fastest time for an exercise.

  • Lets you race against your fastest time (which adds that extra bit of interest to maths practice).

  • Set up the application to display photos from the family album - The photo will change over after each completed exercise.

  • Set up exercises for any number of children.

  • Share exercises between computers using Cloud services like Box and Dropbox.

  • Available on Windows, MacOS, iOS, and Linux.

  • Includes a built-in user manual.
