Calculate 84 Graphing TI

Muy bien 👍, bonito teclado, corre bien en iOS iPad 12.5.7, buenos menús

So helpful for stats! Definitely worth the $30!

App is great but when I try and pull up the table for an equation in y= the app just closes for some reason.

I paid for the lifetime a few months ago but the new update gave me the base features and said I had to pay again

I’m leaving this review because of a glitch and so you see it; your calculator does not allow people to input negative matrices. Like, you can’t input “-2” or anything as a value. Thank you. Please fix this and any other glitches ASAP.

$30 for an app and then half the features still don’t work. They want you to pay monthly for a subscription (which is also not listed under in-app purchases). Glad it was a free promotion download so I didn’t waste the money.

I downloaded this app yesterday morning, a couple hours before AppAdvice sent out notifications to their users about their daily “Apps Gone Free” listings. After I launched into it, I wanted to go into their IAP section (to take advantage of the temporarily $0.00 priced Lifetime Upgrade) — but for the life of me, I could not find it. I searched high and low, trying everything I could think of. I even ended up browsing through nearly all of their online help material, but I found no reference to IAPs. I went into every possible button, drilling all the way down, but I always came up empty. Finally, in the wee hours of the morning the next day, I launch into it again, and voila! A pop-up splash-screen appears with links into the IAP section I was looking for! So, I tap the link to open it, and there it was. Just a few more taps, and… ummm wait a sec. Surprise! The temporary promotional discount was over, and the price returned the regular price of something like $29.00. Curiously, during my first search for the IAP screen (earlier the previous day), app freezes caused me to forcibly quit and relaunch the app, and the pop-up slash screen I was searching for didn’t splash on my screen at all. I swiped up and closed the app, and relaunched it (a few times), but never once did the IAP screen appear as a popular for me… And now that the promotion is over, the needed splash screen happily appears. So, what was the problem in the end? I.H.N.F.I. !! Bugs, or perhaps nefarious practices, are a couple of possible guesses. In any case, I have several other advanced graphing calculator apps, so I will survive.

This has quickly become my go-to app for classes and research. It does everything you could want.

👎🏼👎🏼

love this app
