Landing page captured for the 2026-09-03 issue.

Field notes

JustMath separates siblings’ progress through individual player profiles, including settings, mastery levels, session history, and mistake lists. Its three practice paths are untimed Practice, optionally timed fixed-length Quiz, and Mistake Review, which replays previously missed questions. Grade presets span 1–5, while custom configurations are available for families who want more control. The site also documents a freehand scratchpad for calculations such as long division and says all app data stays on-device.
