## Calcularium 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.

## Calcularium Reviews in United States

### ***** "Best calculator I have run into."
Not only only this app a power house with functions, expressions, in addition to simple calculations, it is also easy to use. Comes with a large collection of tutorials to help users get the most out of the many features this app provides. I love that I paid for the Almighty version awhile back and they haven’t tried to squeeze more money from me. There is definitely honor in this company. They do offer subscriptions that provide many apps, I may consider trying them as the need arises.
Thanks for the wonderful product and good business practice.
-- Unxini, 2024-07-08

### ***-- "Too many ads"
Too many ads
-- KimalaAlwaysLove, 2024-03-29

### ***** "A calculator that doesn’t quite do calculations correctly"
Calculator doesn’t work well with adding subtracting of the same calculation. Have to add numbers only or subtract them only. Heaven forbid you want to divide! Horrible
-- CMGTME, 2023-10-29

### ***** "The most challenging yet useful calculator I’ve ever owned"
It makes my math so much simpler.
-- Fitzfirst, 2023-08-30

### ***-- "Difficult"
I see an ad, but on my iPhone X, I cannot tap circled X in corner to get “granted.” I end up seeing more ads, ad infinitum.
-- Bill Smyth, 2023-08-15

### *---- "It’s not working"
I installed it and couldn’t use it. I press number and it gives me another
-- Akeel Altaweel, 2023-06-20

### *---- "No cash counter Tally"
❌🙅 99$ x❌

Thanks for reminding me to delete app.. 
I’ll be enjoying my 99$ buying multiple of apps.

Lmaoo
-- Update . Update update update , 2023-02-09

### ***** "Daquawn Williams"
I love it 
I wish they had this back in the days
-- holidayNC, 2022-08-23

### *---- "Incorrect calculations"
It will round calculations instead of giving you the whole answer. Half of 0.005 should be 0.0025 not 0.003.
-- jdsujj oh hd, 2022-07-12

### *---- "Completely Wacko…!!!"
Looked interesting until I tried to clear entry, then completely bizarre screens with no explanations or exit. Not sure what was going on, but dumped the app ASAP.
