Ninimaths information
What is Ninimaths?
Ninimaths is an iOS app designed to help you sharpen your mental arithmetic skills through focused, repeatable practice.
Five calculation modes Train with addition, subtraction, multiplication, division, or a mixed mode that combines all four for unpredictable practice sessions.
Flexible difficulty Freely combine operands from 1 to 5 digits, so you can start with simple single-digit drills and work your way up to demanding multi-digit calculations at your own pace.
Column format display Problems can be shown in the traditional vertical column layout, matching the way calculations are written on paper and making longer operations easier to follow.
Daily progress tracking Your scores are recorded separately for each mode every day and visualized in a graph, so you can see exactly where you're improving and which operations still need work.
Game Center leaderboards Compare your results against other players worldwide through Game Center rankings.
Time trial mode Measure your speed under strict timed conditions to test how well your skills hold up under pressure.
