Hey Product Hunt — Jamie here 👋 I built The Daily Integral to turn “I’ll practice later” into a five-minute, every-day habit. It’s inspired by Wordle/Nerdle - but for calculus - clean, quick, and useful for all levels. What you get (every day): - 3 fresh integrals: Easy • Medium • Hard (something for every skill level) - Flow: try first → optional hints → submit → unlock more - Friday Special: one unique, extra-hard problem that makes you dig deep - Streaks: built-in tracking to keep momentum - Free, no login What’s live today: - Daily rotation of Easy/Medium/Hard - Two optional hints per problem (gentle nudges, not spoilers) - Worked solution + integrand graph revealed after your correct submission or once you’ve used all allowed attempts - Mobile-friendly layout, keyboard-friendly input Why it matters: - Short, consistent reps beat occasional cramming - and the payoff is in the worked solutions. After you either get it right or use up your incorrect attempts, you unlock a deep, structured solution that’s designed to teach the why, not just the final number: (a) Clear step titles followed by a plain-English explanation (no symbols) (b) One-equation-per-line maths for readability (no cramming) (c) Explicit bound changes for substitutions and careful algebra progression (d) A graph alongside the solution to connect algebra with intuition—after you’ve genuinely tried, so there’s no spoiler up front Early signal: Within 24 hours of opening it up, we reached ~200 users globally - a nice proof of concept that the format resonates. If you like it - or know someone who would - I’d really, really appreciate a share. Thanks so much for your time and I hope that you have a lovely rest of your week 😊.
