Been using Graphing Calculator Plus (X84) for a couple months now. It’s basically a powerful calculator app designed for TI-84 and TI-83 users. Pretty solid if you’re into math and need more than a basic calculator.
Here’s what you do – you can punch in all kinds of equations and formulas, and it’ll graph them out for you. There’s also a really in-depth manual and tutorial, which is pretty useful if you’re not a math expert. And the MATH CORE support is legit, makes the calculations way more accurate.
Look, if you’re a student or engineer who needs a serious calculator, you’ll probably like this. It’s not perfect – the ads can get kinda annoying if you don’t pay – but overall it does the job. Worth checking out, especially with that 20% discount.
