FAQ

Questions, answered

Which calculators are supported?

Deep Fried Labs apps are built for the TI-84 Plus CE (including the Python edition). If you're not sure which model you have, check the label above the screen on the front of your calculator.

Is SuperCalc+ really a one-time purchase?

Yes. You pay $20 once and it's yours for life, including all future updates. No subscription, no renewal, no upsells.

What's the difference between CalcLite and SuperCalc+?

CalcLite handles core symbolic algebra: expanding, factoring, simplifying, and solving equations — free. SuperCalc+ adds a full Calculus 1–2 toolkit with step-by-step solutions: derivatives, integrals, limits, series, u-substitution, integration by parts, related rates, and trig identities.

Do I need to modify or jailbreak my calculator?

No. Our apps install through the standard TI app mechanism using our desktop installer. Your calculator keeps working exactly as it did before — you're just adding an app.

How do the step-by-step solutions work?

SuperCalc+ doesn't just print an answer. It shows the technique it chose (like u-substitution or integration by parts) and walks through each transformation, so you can follow the work and learn the method — right on the calculator screen.

Does it work without internet?

Yes. Once installed, everything runs entirely on your calculator. You only need a computer and internet for the initial install and for updates.

Can I use this on a test?

That depends on your school's and exam's calculator policy — many standardized tests restrict CAS functionality, and some instructors require a memory reset before exams. Always check your test rules first. Deep Fried Labs apps are built for studying and homework.
