Field notes
The site describes a question flow in which pupils enter answers in familiar formats, including fractions, decimals, ratios, and time. It says recent questions remain on the device with their solutions, and that separate child profiles keep their own attempted and correct counts. The homepage also says no account or internet connection is needed; these are product claims rather than independently verified behavior.
