Frequently asked questions

Is ExaCalc free for students?

Yes, 11+ calculators are completely free, forever. Upgrade to the Student Suite ($4.99/mo) if you want step-by-step solutions, ad-free studying, offline mode, and the formula-sheet library.

Does it work offline?

Yes. ExaCalc is a Progressive Web App (PWA), so you can install it on your laptop or phone and it keeps working in airplane mode, in the library basement, anywhere with no signal.

Can I use it on my phone during an exam?

No, and we strongly recommend you do not. Most exams forbid smartphone calculators and ExaCalc is not designed to evade proctoring software. Use it to study and review; switch to your approved calculator on exam day.

Which exams are supported?

We have dedicated tools for SAT, ACT, AP exams, GRE, GMAT, JEE, NEET, GATE, UPSC, CAT, and more. Formula sheets cover algebra, trig, calculus, AP Physics 1/2/C, AP Chemistry, AP Statistics, and AP Biology.

How do I cancel?

Cancel anytime from your account page: one click, no phone calls. Access continues until the end of the current billing period, and your saved notebooks stay accessible on the free tier.
