What's New in My Custom Math Practice
1.0.1
October 27, 2026
New: make practice tests from photos. Snap pictures of math problems from homework or a worksheet, and the app writes 2 or 3 new tests with similar problems. Also new: scratch paper on every question, so kids can work problems out right on the screen.
