Short daily practice for Calculus I and II, Multivariable, Differential Equations, Linear Algebra and Probability. Every answer is verified by SymPy, a computer algebra system, never guessed by an AI. Wrong options are real student mistakes (we catalogued 745 of them), so when you miss, Nabla tells you exactly which mistake you made. Exam Mode, streaks, a daily plan from your exam date and a formula widget. Free on iOS and Android.

Hi Product Hunt! I'm Hamza, an engineering student. Calculus nearly broke me, not because the ideas were hard but because I kept making the same small mistakes under time pressure: forgetting the chain rule's inside, dropping +C, flipping the quotient rule sign. Nabla drills university math one question at a time. Two rules I refused to break: 1. An AI never decides if you're right. SymPy, a computer algebra system, does. 2. Every wrong option is a real mistake students make, so the feedback tells you exactly what went wrong. It's free to start on iOS and Android. I'd love to hear what you'd want next: more courses, a web version, or class leagues?
