A calm, visual companion for competitive programming. Curated mindmaps, complexity references and quick quizzes to re-glance at everything you’ve already studied — in under five seconds.
Hand-built diagrams for every core topic — colour-coded, colourblind-safe, and expandable with a tap. The visual is the lesson.
Big-O reference tables for sorting, structures and the classic algorithms — the numbers you always half-remember, in one place.
Short, low-pressure recall checks. Answer, see why, move on. Keep a streak going without the guilt.
Revise on your phone at night, pick up on your Mac while coding. iCloud keeps everything together.
Dark-mode-first, generous whitespace, motion that only confirms. A quiet study companion, not a slot machine.
Full Dynamic Type, AA+ contrast, colourblind-safe diagrams and Reduce-Motion fallbacks throughout.
