NeuralDaily.

what it is.

Five new questions every day, the same for everyone, with a streak to keep alive. Practice mode serves unlimited questions filtered by topic and difficulty, unseen and least-known ones first, and the questions you miss come back on a spaced-repetition schedule until you know them.

highlights.

• 184 original questions across six tap-only formats: multiple choice, true/false, select-all, ordering, matching and code reading.
• The daily challenge is picked deterministically from the date: two easy, two medium and one hard question, from five different topics.
• Streaks with earnable streak freezes, XP and levels, 18 badges, and a stats dashboard with a 20-week activity heatmap.
• Spaced repetition for mistakes: 1, 3, 7, 14 and 30 days, then the question graduates.
• Fully static, with no backend and no account: progress lives in the browser.

how it's built.

React 19, Vite, TypeScript and Tailwind CSS 4. Every build runs a script that validates the whole question bank, and the scheduling and streak logic has its own tests. Built with Todd.
