Quick Overview
Ninimaths is an iPhone app from Ninicode Inc. that helps users sharpen mental calculation skills. Offered free in the Education & Reference section of the App Store, it provides focused practice sessions across several arithmetic types and includes tools to monitor improvement.
Practice Options
Choose from multiple calculation formats to target specific skills or mix them for varied practice:
- Multiplication drills
- Mixed-operation sessions
- Single-operation addition practice
- Division exercises
- Subtraction problems
You can customize the difficulty by combining numbers that range from 1 to 5 digits, allowing exercises to be tailored to different age groups and skill levels.
How Problems Are Presented
Ninimaths displays problems in a column-style layout, mirroring the paper-and-pencil method taught in many classrooms. This vertical presentation helps learners visualize multi-digit operations and supports the transition from written methods to mental strategies.
Tracking Progress
The app logs daily results for each practice type and visualizes them on a graph so you can observe trends and improvements over time. This makes it easy to spot strengths and areas that need more attention.
Competitive & Timed Modes
A built-in leaderboard via Game Center lets players compare scores and compete with others, adding a motivational, social element. There is also a time-trial mode for testing speed under pressure and building quick-recall ability.
