What people like
- Works great for school math
- Free features are actually useful
- Easy to type numbers in
- Simple and straightforward interface
What they complain about
- Pop-up ads interrupt calculations constantly
- Ads play automatically and loudly
- Too many distracting visual elements
- App feels slower because of ads
Just simple and Easy
Does the job no fuss, easy UI
Premium Subscription Is POOR
Very Poor App Due to Ads Recur Even On My Paid Subscription!
Me
It is good but they need the greather than, less than, greater then or equal to, and less than or equal to.
Too many pop upads
Too many pop up ads
Good functions, Too many ads
Recommend going with the premium version. When doing important calculations, you don’t want to be stopped from doing work due to ads.
It’s awesome.
I never leave reviews, but this app is so worth it. It’s so easy to plug in the numbers exactly how I want them. Who cares if there are ads? The 15-30 second video just plays at the beginning. It’s not that big of a deal. There are so many things that you can do on the calculator that are free. If you’re in high school, you’ll be fine. Usually apps give you very limited options before you have to pay; this app is not like that, which I really appreciate. Whoever made this app, thank you so much for making a scientific calculator app that’s really convenient.
Terrible Experience
A calculator should never have popup ads. Disgusting.
Nice
Very nice layout and the price is right👍
Ads
Ads interrupt computations too often.
Doesn't throw an error mismatched (()
example: ((10-1)x0.1+1/(10-2) should be an error (missed closing bracket) not 1.025 . Maybe it is a setting but I couldn't find it. There is a fraction function but it would be nice if it informed me I have a syntax error. Otherwise it seems to be a very good product not that I have tested its full functionality.
分f哈哈
的v不好
No thank you for Adult Content Ads!
Temu was being explicit!
Pretty good!
Layouts a bit confusing to me but other than that I love it!
RIP to this app and others
When I first downloaded this app it was so useful and easy to use. Now it’s annoying with all the ads. We literally see ads/commercials 24/7 it’s soooooo annoying my goodness. Idc how many seconds it is. I don’t want to see that on any apps especially a calculator app. It was cool while it lasted.
ads cover entire screen
obnoxious
Good
Nice
too many ads
^^^
So confused if the trig is using radian or degree
The calculator is good but yam so confused if it is using degree or radian
Used to be a great app
App used to be perfect, but now it's littered with pop-up ads
Good Scientific Calculator
-1 Star too many adds -1 Star need to pay for button shortcuts Otherwise good scientific calculator
Major upgrade from the included Calculator
Love it.
ADpocalypse!
Used this calculator app for 9 years cause Apple's basic app at that time didn't have scientific functions. It was great until developer got insanely greedy just within the past year. I didn't mind the banner ads, those were around since the beginning and they gotta make some money. Then dev decided to add a timer that autoplays a video ad on your entire screen every 4 minutes the app is open! If that wasn't obnoxious enough, it now plays a video ad if you let it sit for a few seconds after EVERY SINGLE CALCULATION YOU DO. That did it for me. Thankfully, it seems that years later Apple has finally added a scientific calculator to their calculator app so I won't be needing this one anymore.
Good but the ads ruin it
Used to love this app but since the app is full of ads it can be really slow and annoying
Not easy
The trig functions are a bit strange to use. I have used easier calculators in the past.
Great, but lots of ads
Great, but lots of advertisements
#1 super brilliant calculator
The best of the best!
A calculator app with periodic full screen ads. What a joke.
Like title says
Great
I think it’s good but I think it could (ave the remainders when you divide like not just .8 it could be like r4 or something but otherwise really simple and nice
Ads
It’s a calculator with ads, what did you expect
Works well but obnoxious ad placement
Works well but obnoxious ad placement
Grades
Fetter
Ads Everywhere
This app used to be great, now I can’t even open it without it shoving 30 sec of ads in my face.
Pretty good
Wish it didn’t have ads, but that’s ok (it is free after all). I like the little ding noise it makes when you press =
Dislike the new update
Having been a user of Calculator# for years, I can honestly say that this update feels like a downgrade. I used this calculator regularly in the classroom and have found that simple functions such as pressing the equals button successively so I don’t need to re-input the calculation doesn’t work anymore. The interface is also unpleasant and that signature bell sound when pressing equals is gone! I regret updating to this version and if there is any way I could get the old version back, I would at the drop of a hat!
Too many ads in free version
I don’t want to pay for a simple calculator. This app has too many obstructive ads.
Best calculator I have used free without ads.
The app is overall amazing, but I wish it was supported on more platforms such as android and windows. And I especially enjoy the ui.
Hate popups- App Sux!!
Hate popups. They are annoying and have embedded sound which blasts out even if you are in a meeting. This app sux!!
Great
This calculator is great and it works perfectly fine for my science class and for functions as well
Calculator tool
Not nearly as happy with this calculator as with the previous version. Advertising on a calculator function, really? Concentrate and have advertising flashing at you? Time for a change...
Works as intended
Works as intended
Just what I need
I’ve been searching for an app for my IPad that works like a graphing calculator for math homework and here Calculator # (weird name though) is to fill that need.
Ads!
Inappropriate ads and ads every minute
Calculator
It ‘‘twas decent
Please stop accessing clipboard
Would rate 5 stars because it works great, but WHY does this app always paste from my clipboard upon launch? There are exactly zero reasons why a calculator needs to access that information. Very suspect, And for that reason you should not get this app. I have no idea what they’re trying to obtain.
Distracting UI elements are keeping me from purchasing the full software
The blue button array at the bottom is very distracting while using the calculator. It annoys me and is very distracting and hence I am not purchasing the complete software. If you can turn it darker or carbon coloured, I will.
Fantastic
I love it
Ads and doesn't even work
There is so many ads it is ridiculous. Don’t waste your time. Everytime I put it in an equation there is an error. There is no help for it and it sucks. PLEASE DONT GET IT.
So helpful
Is the perfect way to have a calculator for schooling. That works for all the requirements you need.
Unintuitive
The “tutorial” alludes to functionality that is at best difficult to work out. I tried entering a system of equations to solve, and got as far as “y” - because the equals button was not available in the context... not sure why. The help was hopeless and the video was useless marketing.
Correct
I find there are too many ads but is a cool apps!;)
