The Daily Integral is a daily calculus challenge inspired by Wordle and Nerdle, designed to turn practice into a simple habit you can keep. Every day we publish three fresh integrals: Easy, Medium, and Hard, so anyone can start at a comfortable level and still feel stretched.

You try first; after you submit, you unlock a clear step-by-step worked solution and a clean integrand graph that explains the reasoning as well as the result. Optional hints keep you moving, streaks help the habit stick, and every Friday we release a new “Evil” difficulty integral, a 48-72 hour special with two-phase rules and a Wall of Fame to recognise those who complete it and send proof of their working.

We built this for students, teachers, tutors, and lifelong learners. The Daily Integral is completely free with no strings attached, and it works beautifully on mobile.

It is ideal for warm-ups, revision, and staying sharp in just a few minutes a day. Within a week of launching, we surpassed 2,000 users worldwide, and the community keeps growing.
