This app is remarkable for its careful workmanship. In spite of the wealth of features, they are reasonably intuitive (if you know the math) and logically organized. Includes a financial calculator and periodic table. It is free, with unobtrusive ads on top. Attractively laid out. Very highly recommended.
This is a really great must-have app. It is a most versatile and comprehensive calculator, amazingly user-friendly and having many useful features and diverse modules to cater to various modes of calculation as per individual requirement. Highly recommended for those involved in the fields of engineering, technology, science, and accounting. It also provides for themes and display enhancements to take your calculator experience to a new level.
Spend some time perusing; this calculator does EVERYTHING. I use it when I'm checking my 11 yr old's homework (prime factors, etc.). I use it in physics; converter and constants. I use it doing carpentry (what's a third of 4' 5+5/8"?), and cooking. Chemistry: periodic table, molar mass calculator, etc. Graphs functions, solves linear systems, polys, etc. ENG format with Latin prefixes. And on and on and on and on. It's also highly customizable. Best emulator I've seen/used;Bravo Roaming Squirrel
This is actually quite a nice app.But as always(like with other apps) it has its advantages and drawbacks.To mention some advantages I personally like the "Quick formula" section and the fact that one can print a graph as a pdf-file.I also like how simple it is in Graph mode to get integral / differential values.and how to change the range of interest for an area on the graph itself without having to enter lower and upper bounds.in a formula. The main disadvantage is its interface.I just don't like it.With that I don't mean the main interface:it is sometimes really unsual how to enter equations.You actually have to read information given on the display itself to figure out how to do it.This is counterproductive.Why not just using the standard and more intuitive approaches? Nevertheless: I have 3 math apps on my smarty and one of them is this one.If I had one wish free:please developer reconsider the interface.I just want to enter my formulas,equations without studying the display information first.I'll give you 4 stars - it would be easily 5 - if the interface was to my liking.It is possible that it is just me who moans about the interface and others are happy with it.... The main thing is: the app works fine and does what it promises.Kudos to the developers for all their hard work
25 years ago i used magnificent, extraordinary, out of this world CASIO FX calculator (and i got my degree). nowadays, aps like this can perform magic even better.
This is an amazing calculator that does so many functions. I am very happy with it. It does everything I need, technical, financial, statistical and graphing just to name a few. It is the best calculator out there and I have checked the accuracy - superb!
I was just looking for a quick converter. This converts far more than I expected including currencies, includes more units than I knew existed (I know some physics but I'm not a scientist), is a great calculator and keeps improving.
This is a very good calculator, it gives nearly all the options, easy to use, memory look up is good, it displays 10 digits, but probably has three more digits not displayed, this is my other favorite scientific calculator
Gives me the feeling of having my good, old (physical) calculator again. Lots of functionality, great UI. I have used it for a number of years.
Excellent: it performs almost all mathematical, physics, statistical, engineering and lots of other calculations as well. Great app!
I appreciate the efforts you made, bring some more improvement in equation solving part. And the "ln0" expression shows "log value cannot be zero" but this is equal to "-∞".
Used for many years. Now it displays stack=1 and X=0 on the screen for no reason other than to get me to their advertisers so I stopped using it!
Best All In One Scientific Calculator Ever. It's all I wanted in a calculator. I recommend it to everybody. Cheers.
Shame about the mistake. They decided to implement BIDMAS (or whatever you care to call it). 25+3x4 does not = 37 it's 112 25+(3x4) does = 37 Or at least that's how my 40 year old Commodore calculator does it. Passed all my engineering exams using it.
The only calc app you will ever needed, For the past 10 years i have used various calc apps and finally settled on this,enough said how good this one is.
Further to my previous review, I am now changing my rating to 5 stars. As this is the calculator that I use for all of my calculations, basic, time, conversion,
Complete calculator in all aspect. My humble request to developing team is make this apps for Windows platform also.
Excellent great businesses calculator)"
Very nice except digits are limited to 30 and Pi to 16. The constant ads at the top are an ugly intrusion
Highly sophisticated, easy and simple to manipulate for those with the acumen to engage this machine.
Overall, very good, I use it all the time for various things. Have it on every Android here.
The best! This calculator is simply THE BEST. It does everything and is easy to use.
Awesome math engine. Great job. This is the best app. A great math machine. This App is unbeatable. Number One.
Totally Superb. Far more than a calculator, more like a library of numerical knowledge.
Great functionality and always adding new. Also great reference section.
satisfied, beside basic sci-calc, this gives us currency converter as well as many units converter!
I've used this calculator for many years it's one of the first apps to be downloaded onto every new phone I get!
the best calculator so far. actually it is the father of calculators which all work well in one.
Mostly great; I've found very few bugs in this calculator.
Excellent App. Why? It's not for the unmathematical person. You must know a certain technical vocabulary and algebraic notation already, at the very least, as on any matter. The virtual keyboard is packed with "functions", so each key triggers a math function if tapped, and yet another if pressed and sustained a bit. And that's just for the customary calculator use. This version now does plots! A god-send.
