Description

Here are Calcularium users describing the app:

"You know how you're slowly calculating something and you're in the middle of an expression so you want to know how you're doing? Yeah well that's real time calculation and I couldn't find an app that did it right, tried dozens of them and still nothing, BUT this app does it the perfect way, actually the way it should work, this app is definitely worth it, thanks a lot devs, big love.

Edit: OMG this is better than I thought, I just noticed the tutorials given and this app has more functions than I noticed, this is super amazing, devs, you're the best." – Anton31kah10

"I mean it literally. The tiny app packs impressive amount of useful stuff for a mere calculator. I would say it’s like mobile Excel. Math functions, unit conversion, currency exchange rates, and, even simple programmers functions. I wrote a small formula to calculate tips for our county. Easier and better than any tipping app!

I hope the developer expands these functions for Shortcuts and Siri. This would be real killer app! Thanks guys!" – Z!KeepeR

"What looks like just a clean calculator app is in fact a powerhouse full of advanced features you could only get with custom Excel mega sheet." – AlexDbk

"You can find a lot of different kind of calculators but this is something completely new and awesome. It is not an another boring calculator. This is your real helper if you need to calculate something more than 2+2 :). Tutorial is great and helpful. History, customizable functions, variables, converter and much more. Great! It is definitely the next generation of the regular things." – Lysyk

CONTROL BY VOICE
Calcularium is also can be controlled by voice and has the ability to understand spoken math questions and calculate the answer. Tell it: "6 bottles by 15 dollars” - and it will give you the right result! It works by using verbal numbers and mathematical operations.

FLUID DESIGN
The design language of the Calcularium is based on tokens. All tokens are of the same structure: the left part shows a type of the element, the right part has a result or an entered value and its name on top. In addition to tokens there are pure numbers and math operators.

HISTORY
You can set an expression as a variable with the goal to use it afterwards in other expressions and give every component a clear name to recall what it stands for easily. Create a calculation, and next time you reuse it from History section, every component will clearly speak to you.

Too ambitious

This calculator is confusing and difficult to use because it appears to be trying to do too much. [Note to developer: at no point have I said this is "complex"; I use other calculators with far greater functionality very successfully]. Slick graphics do not always help, especially when some of them get in the way of what one is attempting (with some difficulty) to actually calculate.

I'm sure the developer knows how to use this effectively, but I've struggled to do what I've previously achieved easily with other apps. Please simplify it and make its sometimes unexpected and peculiar graphics easier to read.

[Edit after being contacted by developer]…
I've just downloaded this again, in order to re-appraise.

The interface is poor. The calculator is set too low on the screen, very close to the annoying advertising strip as if trying to encourage an accidental click upon it. This further slows down use of the awkward button layout - which itself requires too much effort due to its small font and unusual spacing set in large space. Continuing my effort to familiarise,
I was presented with a strange (and very difficult to read) instruction which waved around repeatedly. This was another unwelcome distraction which I eventually worked out was telling me to shake my iPad 'to undo'; but since it sits mostly on a desk like a small laptop, often on charge, I have no desire to pick it up and thrash it about!

I could continue this review, but what's the point? I've already spent too long bothering (twice) and have no desire to follow up the suggestion that I also email developer!

I don't like this app. There it is, plain and simple. I think the two star rating you first received from me was more than fair.

…Another edit after seeing the disgraceful statement now made by the developer that I have made "false statements". Why would anyone do such a thing? I've stated the facts of my experience, plain and simple; and then gone into greater detail to explain further, as you asked. I set out to help you by giving my opinion. Then, after being notified of your response, I had another look to see if I'd been "harsh" as you claim, and after you'd asked what I was finding "complex".

You asked for feedback. Here it is, again…
My opinion is that this calculator is awkward to use. I'm pleased for you that others like it; but my review can only be based on my own experience. I find it really awkward and I do not like it, at all.

[Actually, I was too generous. 1 star]

Developer Response ,

Really not nice to write false statements. But a would put it simple unfortunately you have the right to do that in review. Try sad that you can’t take somebody huge and really great work that liked by 100K+ people.

Good luck!

[UPD]: We really wanted to help and get your feedback. Instead your answer was harsh and not nice to people who didn't get any penny from you to try a great product. 

And by answering once more time, you just confirmed false statement about calculator and about you have not been harsh. We're not going to have you back. Great product deserves great users, and we have them a lot! Thanks and good luck!

We’re right about false statement! Still nothing changed. False statements.
