About

Add & Subtract Master

Features
Read full description

Add & Subtract Master is a focused iPhone and iPad practice app for elementary written addition and subtraction. On iPhone, learners keep the full calculation visible while writing with a finger in one enlarged selected cell. On iPad, they can continue writing directly in the calculation cells with Apple Pencil or touch. The app checks the final answer while helping children align digits and build the flow of written calculation. Handwriting is read as written, with a keypad available when recognition needs correction. Only digits corrected during review are stored on the device and used to tune recognition for it. Learning can be turned off, and saved corrections and the personal model can be reset at any time. Missed questions return after a few more problems. Choose 5, 10, 15, or 20 minute sessions for home learning, tutoring, or daily practice. One-time purchase. No ads or additional purchases. Handwriting images, corrections, and the personal recognition model are processed and stored only on the device in use. Nothing is sent off-device.
