A gamified study companion that says it will turn lessons, questioning, and spaced memory into a curriculum spanning GCSE to PhD.

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

Field notes

Kerfox is currently presented as an initial-testing project rather than an accessible study app. Its proposed workflow combines simulated visual lessons, questions with three layers of explanation, and review that returns difficult material before it is forgotten. The public page demonstrates the concept with a force-and-distance physics sequence, including a GCSE multiple-choice question, while release references point to planned Google Play, web app, and app store testing.
