illustrative previewOne short calculus drill a day (derivative or integral). Texts the user a problem, grades their reply with a one-line explanation, reveals the answer when they're stuck or wrong, and tracks which rule types they miss so future drills target those weak spots. Free, no payment needed.
what it'll do
before it starts, it'll ask: what time should the daily drill text go out? default 5pm Africa/Lagos
