要钱

好多功能要钱,别下

Please look

Please add a dark mode. Gives the app more personalization. Also missing a lot of ti-84 features like numeric solver. And you should definitely make the numeric solver specifically free, ya know. 😉😉


Wish y’all success!

希望可以出个2nd的功能

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.

能有中文吗? 有教学视频吗 不这么会用。

如题

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.

我不会用啊

我不会用啊,怎么用啊?

好用子

挺好的 省得画图计算了 数学好帮手

立减210¥

虽然没啥用

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.

没法拖动函数…

希望整改

Good, but:

Add some things:

1. Add settings button: Where we can change the Color Theme, for example. Also display there the subcribtion, so that we can see if we have premium now successfully and for how long.

2. A standard Calculator: So that we do not need to have two apps and are be to switch between them easily.

3. App Description: Show us the Features that we get when we buy Premium.

Thanks for your answer in advance.

Response from developer

Thanks for your feedback. 1. You can change the Color Theme in two ways: Press the MODE button and then tap on Change Keyboard Color. Or by pressing the HELP button (bottom left) and tab the button Change Keyboard Color. Regarding subscriptions, they are auto-renewing and last until you cancel them or if you have Lifetime forever. After you cancel them in your account settings, you see for how long they will stay active. 2. What do you mean here in more detail? You can use the main calculator with more basic calculator commands visible. More advanced calculator commands can be accessed in the MATH menu for example. 3. We think about adding it to the description. Assuming a user would not directly get the subscription and check out all the different calculator menus, he would see the commands marked with a PRO label that can be unlocked through a 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.
