Have Financial Statistics for my first year of college, of course when they told me to buy a Ti-84 (upwards to about 140$) I was extremely reluctant and wanted to find a more affordable option. I downloaded their Ti-84x (the free version) , but it sadly didn’t come with all the formulas I needed. So I forced my bf to by me this one, and it’s absolutely amazing !! I understand that you may look at this and go “5 dollars, heck no” but trust me, spending these 5 dollars is way better than spending 140$ for a calculator you’ll never use again outside the class.There was only one instance where I had trouble, but before I figured it out myself, I contacted their Help Center, asking for assistance. Afterwards I was able to clear the error myself, but their help center reached out to me, giving me instructions on how to rightly input the formula. Took less then a day to contact me back, and they were extremely helpful ! Great app, great staff, and overall absolute perfection !

First of all, its a really good calculator. But it could use some improvements.I would like to see list editing functions. Not like a menu, but rather a function that can “splice” a list and remove any unwanted elements, then save to a new list, while preferably retaining order. That would be nice, especially if you wanted to divide a number by a list and find you can’t because the list had a zero as an element.Another thing I would love to have is a recorder function. Basically something that takes all values from a function and puts it into a list. This would allow you to, say, use a function in statistics. And one final thing I’d like would the ability to iterate a function.

First off, this app’s purpose is to replicate the graphing calculator and make it much much more cheaper, so if you search up “how to use the TI-84 Plus calculator”, you can use a lot of the search results for this app. It’s really efficient.That being said, you shouldn’t give less stars because you don’t know how to use this calculator. They even provided a user menu for you! Anyways, to exit “Y=“ tap on “2nd” and “MODE”. You can literally see the “Quit” word right above the “MODE” button. If you are too lazy to find the buttons, you can still search it up on the internet, but your laziness isn’t the developers’ fault.

Thank you to the people that created this app and for only $4.99 ???? What a STEAL! I’ve never taken the time to write a review for an app but this app saved me from having to purchase an actual TI-84 calculator that costs over $140. I needed it for my college STATS class and only for the remaining 3 weeks of class so this was the best investment I made. I didn’t have any problems with my answers being incorrect because my professor would show us how she got the answer on her calculator and I would try it and always accurate! If you’re a college student GET THIS it’s worth it i promise!!!!
