Glitch
Overall, I liked this calculator. It was similar to the ones that I am used to. The color choices were nice and I was able to slide it wherever I wanted it to go on the screen. The most important part of a calculator is accuracy. I was very disappointed when I typed a function into a the y= and pulled up the table that my domain was incorrect. There was a random value instead of an error. I even have a recording if this. I tried contacting the email, got no response, so cancelled my subscription.

It is not free as advertised
They will charge you down loaded. Avoid this if you can . I did not see my review
Just like a TI84!
So helpful for stats! Definitely worth the $30!
Table issue
App is great but when I try and pull up the table for an equation in y= the app just closes for some reason.
Already paid
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
Review, and I paid for this
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.
Response from developer
Thanks for your feedback. To enter negative values to a matrix, make sure to use the negation key "(-)". The normal "-" key won't work here.
Can’t rate zero
$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.
Response from developer
If you have the subscription there are no functions locked. If there is something locked, you obviously are not on any subscription.
Bugs caused me to miss out on the IAP promotion!
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.

Thanks for letting us know that you experienced some bugs on the day of the promotion. We are very sorry for the inconvenience. Also, we don't know why the pop up didn't appear for you and some other users that wrote us. For the majority, it worked. We'd like to give you a promo code to get the Lifetime subscription for free as you participated in the promotion. Please send us an email to contact@hypercalc.org so we can send you the code.
Fantastic App
This has quickly become my go-to app for classes and research. It does everything you could want.
