Reviews From google play store

Although this appears to be a nice calculator, it's incomplete, or made for those who have never used a real calculator. For me, it's useless. With no RPN (Reverse Polish Notation), I almost always get the wrong answer. I have used only a RPN calculator for almost 40 years now and have forgotten how to use calculators with an equals sign. For this to be so complete, how did the devs overlook RPN? (Maybe they have no clue how to use it?) Back to my virtual Hewlett-Packard and its RPN.

Was doing really well then suddenly it decides to leave off numbers on the answers. Which caused me to miss the questions on my test. Grr Grr. Now I have to do a double check on another caculator to confirm an answer , Grr Grr. May just switch. I really do like this one if we can figure out its problem. ????

I've been searching for an advanced calculator that can do anything I want. This is that calculator. I had the one from Google but you could only do basic operations. So I went looking for one and saw this. Only downside is that there's ads, but they are tucked away in the bottom. Excellent calculator!

No complaints. Well, I can't find a modulus function, so one complaint. That's it, though. Intrusive ads are kept to a minimum. Hundreds of calculations. It says in app purchases, so I was originally worried about having to pay for the more specific calculators, but it's all free. I also love the art style.

This app is amazing. So instead of saying how good this app is, I'd rather debunk some of the negative reviews. There are no ads anywhere on the screen that blocks content, only pop-ups; this is so the devs could keep making these great apps. No, it doesnt ask for you to rate it all the time; for me it popped up after a week. The ONLY problem I have with this is the banner at the bottom asking for 3.45 USD for premium (I used the calculator for that). The app itself has a dark mode so I love it

I am so pleasantly surprised with this calculator app. So many times I find myself googling the conversions from inches to meters, feet to centimeters, etc. I'm so happy to have found this app. I can say easily that I will use it often. I especially love that it has all types of conversions and calculators built into one smooth, polished app.

Almost full marks. One drawback is that one cannot calculate the loan amount backwards. That is entering one's available monthly payment, the interest rate, and the number of months, to get the maximum loan amount he can afford.

Beautiful GUI with (optional) dark theme, smooth navigation, tons of features, almost everything can be rearranged and tuned to user needs. You can enter value in any field on the current screen of any conversion to get result in other fields. I wish only that there would be an option to save entered values (eg. fuel price), so the field with previous entered value would be filled next time you open application.

Please add a drafts man scale(scale conversion) calculator. I know it also can be calculate through algebraic ratio based calculation but it will be nice and easy to have remote calculator in app to calculate scale. It will really help architect, engineers and other professional that work on scale based work. Thank you

Just installed this App and I was about to delete it because it was showing up shortcut settings area without an invitation, but I started to check it out and it's a very cool App with lots of extra features that you wouldn't expect from a calculator App that I'm now using and enjoying. My complaints are it doesn't round tips, it doesn't mention the exact name and manufacturer's name on it, and I should have gotten a warning of it's intent to show up in that area ahead of time.

I'm not a heavy calculator user, but gosh... this one App is incredible, features tons of useful tools, converters, equations solver, and a simple and amazing calculator widget. Great design, the entire layout looks fresh and elegant. Kudos to the developers, sincerely.

This app has succeeded to define the meaning of a calculator as it did not focus only on BODMAS but other stuffs that require a calculator are also involved ... Great app. As it might not be the end just to add up, a tally counter tool would make this app much more great, Other wise i rate it as one amon the best calculators to be used as an android app

this app has helped me SO much on gerting an idea of the pattern to convert cm to m (the decimal moves two spaces) Km (5 spaces) and mm (add a zero) but it includes other subunits like nano, deci, etc; it has certainly helped me with chemistry. Their convertions are pretty complete unlike others I've tried for mobile. Also the favourite button is incredibly useful. I already disabled my dull and mediocre default calculator for this one. I cannot think of a con for this app

Absolutely love this multifunctional calculator, all the different options of mathematics involved in this app are incredible and a great learning tool! GREAT JOB!!!! I seriously believe that this should come preinstalled on all phones.

Feels very gimmicky. There are a lot of things (like bodyfat calculator) which cannot possibly be accurate because you need more than just weight, height, and age to calculate bf%. There are fancy graphing tools, which are nice, but It still doesn't provide basic things like proper fractions (having things on two lines over each other rather than just a ÷ sign). No really useful tools like calculus stuff. All of the tools literally just plug your numbers into formulas.

For a free calculator, it offers many functions which I am very happy about. It definitely helps me save more time instead of needing to go online to make unit conversions. Thank you :)

It has all of the conversions I need in any given situation, which is exactly what I was looking for. I don't like that it's display name is "Calculator" because it conflicts with the two other "Calculator" apps I use - but that's not a deal breaker.

It's quite helpful. I recommend you use this whenever your shopping and you find a discount but you just can't calculate it then and there. Also great for helping kids with their homework. My kids love the app and now they never have to fail a single test again. Thx all-in-one calculator.

It's good option where all type of multiple calculator is there. But generally most of people's are use basic calculator first. I've purchased it and then request for history with date wise on basic calculator. Google has that in his calculator app. So I've already switch to Google calculator.

I needed this. It has lots of different types of calculators I didn't know I needed. Seriously. Since I can play with it for a while figuring out what it can do makes it even better. When I need the calculator it is there and I know which one I need and how to use it.

Excellent calculator that does what it says it will. Also included in the free version are other math tools. Easy to use and has full functionality of a regular calculator!

Still missing so many features!!! A tally counter, a speedometer and a timer! Just a little away from being the perfect app. But as it is, a great app. A pleasure to discover such an app exists. Almost as good as an imagination! 5 stars!

I am quite surprised. This calculator is actually all in one. I have never use a calculator like this. It has several fields to use. Amazing! But if you add formulas then it will be even better!

This application is really worth to download. And i appreciate that this application literally offers such a versatile service, from basic calculator to advanced scientific calculator and from length conversion to energy conversion. I would refer it to engineering students and others too.... I would thank the developing team for it's creation. Respect and Love from AMRADITYA PRADHAN...

It just works. Such a snappy app, as in it's very fast. Really really like this app. I removed ads as I enjoyed it so much. Thanks for a great app.

This whole app is amazing it is so simple and user friendly it covers every normal life problem will figure out what wattage or volt you want. I have friend who drive trucks for a living that use this app daily. For calculating the weights on their freight to help with fuel cost and mileage . THIS IS THE ONE. TY

Overall it's great. More tools than I expected. Only thing was more ads than I see with other apps. Actually pretty prominent, can get annoying.

This is by far the BEST calculator app. You cannot find a better app on google play! You might as well get the app, the space it takes up may be high but its worth it. I was straight up about to code my own app. This saved me so much trouble

Great set of functions. I got it mainly for unit conversions, and it's been perfect for everything from construction measurements to cooking.

Great one but ads This app is a real good combination of google calculator and mi calculator. (What i was searching for). Has history recall and scientific version Only down was Ads/pro, but looks like that is the only way developers can survive now a days. Thanks and keep improving.

It's everything it says it is works great easy to use and it's an asset to have. Hundred percent better than the stock calculator other phones come with.

A fabulous app for students to get quick solutions to all type of sums. Also can be a good aid to people who have complex mathematical problems to solve in day to day work. In short a must have app.

The app is really versatile and dummy-friendly. The bad thing is that on the "finance" section it does not allow you to use a fraction (e.g. 6.25% interest which makes it useless as a financial calculator. Thank You! Ben - Cape Town

Never thought I would get excited about a calculator. But I have to admit, this app is cool. Design, options, functionality, all of it is well thought out and well executed. This app puts the cool back in math. I think I need to get a pocket protector...

The app is great! A job well done! However, i am giving it a 4 star for now because of the lack of an AntiLog calculating feature. Please think upon adding it. Thank you!

Excellent tool. It provides calculators for conversions (distance, volume, weight, area), plus loan payment, tip calculator split among several people, and many more. Very user friendly.

This is my first time writing a review and its for a good reason. This app is literally the best! You have everything you need in one app and its very easy to use. ive used a lot if calculators, but they were always confusing. this not only solves that issue but it triples the expierence. if there were 100 stars i could rate to anyone they would l go to this app. It also is a basic tutor, for FREE! Because it shows the solution. Definetely going to recommend to my friends! Thanks for this app!!!

This app is perfect! It does everything it needs to do and it does it well. Everything is customizable, there are many well laid options. You can feel that a lot of work went into it. A MUST HAVE!

Amazing!!! It is so easy to use and it has got tons of interesting choices! Absolutely recommend 😊

I love some of the tools, and I absolutely love just having a calculator which have brackets. Would love them to make graphs and division above and belove a line.

I find it useful but of course, the ads were annoying. I get that it's useful but I deleted it after a few months cause it's not really the kind of app you will be using all time in all occasions. (Unless of course, you need help in your homework.) All in all it's a useful app and is actualky pretty handy considering it doesn't take up a lot of space in your phone.

I've used many other calc. apps. This is free & by far the best. I use on daily basis, it's not only is a calc. app but many other features such as conversions, algebra, finance tools, BMI calc. so much. At only 25.4mb with minimal cache for how much I use. I highly recommend this app. Great job developers, your hard work hasn't gone unnoticed 👍

I use this app literally every day, multiple times a day, and still find new uses for it! The built in unit converters are awesome, well organized and easy on the eyes. Ads are present but not intrusive. This is exactly what a free app should look and behave like. Thanks devs, keep up the good work!

So many features that I keep finding more to play with for all of my mathematical questions. I do see a few options "missing" but honestly, they are not essential (thus the full 5 stars). Could be put in a future update once I remember to send a suggestion in the feedback section. But this is a very well loved app.

Almost all people have this application, it's too much help for all purpose of calculations, this application is too much help for any student and business sector and normal people's.thanks for creating this big idea.

Fantastic! I would suggest you guys add an option to see the operations or formulae included. That would improve it further. Btw, it's great.

If there's any reason to have a standalone calculator app, this app justifies it more than anything else. The most pretty looking, most functional, most satisfying calculator app. Great purchase.

Great converter/calculator app so far. Conversions are laid out in a logical, and useful format and I have been let down yet for as far as units. Love that it has a Dark mode as well.

Wonderful expirience... i didnt expect this much.. Having solution to every problem at one click and at ur finger tips is a great achievement. This app is supper good

Good calculator/converter with potential to be great. Here's where I think it could use improvements. 1) Some functions are limited (e.g. shoe size goes only up to US size 14). 2) Most menu items and field names are truncated (even on my tablet (e.g. "" instead of "March", "..." instead of "Add", basically first 3 to 5 characters of almost every word. Other than that it's quite nice.

Fantastic calculator with more tools than I know what to do with. But it couldn't determine if 2^82,589,933 − 1 was a prime number so it's not perfect.

so far everything is working absolutely spot on. I'll wait to see how it holds up in the near future. I currently had 2 all in one calculator apps and the other one has failed me. like it just seems to not open properly anymore and I have been using it quite often but now it's this apps to turn to see how long it will last with out a hitch

Love the extra conversion tables as options. Could add a materials and labor option for easily bidding jobs more efficiently otherwise definitely better than default calculator that comes with phone

Love the app! It does everything a converter-calculator would and so much more. one suggestion, it would be cool (at least for the angle conversion) to show an animation in the preview screen above the conversion UI. Otherwise, it just seems like dead, but artistic, space.

Such a wonderful app with many functions a true scientist shall requirr in dsy to day activities. Being a field Ecologist, I found it truly useful; the adds are minimal. Thanks to the programmers.

Excellent app that has pretty much all the calculators you can think of it even has a currency one (really useful when traveling) and the design is pretty clean looking and you can acces normal calc just frok a right swipe

Its a very good calculator with loads of extra options (i.e. converters for all sorts of things, binary to hex to decimal, health things). Cant fault it really, does everything I need it to and more.

As useful as something really useful. It can convert volumes, currency, etc. Solve equations, draw functions... I like this app! What's more it looks great.

Very good app for school. Helps with homework and even has an option to learn the formula. Very good.

Great Interface! Excellent choice of sub groups within a topic. Educational as well. Can learn alot here. Easy but very thorough.

Personally this app had the best user interface, easy to use and most important it is accurate, the price is fair, so message to dev team, keep up the great work, u earned it guys. 😀

The floating calculator and vast conversion unit options make this THE calculator and unit/measurement converter on Android! Converter has more units and types than you can shake a stick at, and the layout of conversion table when you enter your info and hit convert is easy to pick out the number you need quick while offering a list of different units instead of just a 1 on 1 direct conversion!

This is the best calculator I have ever used so far. It has a variety of options and its costomization features are impeccable. It really is an all-in-one calculator.

Simply a Fantastic calculator with tons of functions. I don't think there's any other calculator of this sort. One thing though, I think it fall short on children's shoes sizes please consider adding more accurate information on the section.

I will say that this is one of the best calculators I've ever seen. This should be more popular. It has a lot of functions (Things to calculate). I Really Like it!

App is good but create a custom unit option not available. For example local length or area calculation is required frequently. Please provide this feature as well.

This is great! it has plenty of calculator options, converters, etc. I can't recommend it enough, it has so much more than you think you need.

#NICE_ALL_IN_ONE_HELPER It is an excellent calculator which have tons of features grouped and separated nicely with cute tiny icons also . There is not much of ads (I appreciate) And its mostly free . **ADVICE** Please add graph ploting feature complete like using a function or equation in all 1-D , 2-D ,3-D in a manner that we may be plot qny graph or plane in plane or space or else !

This app has many choices of types of calculations you can perform. I also like the favorites option for the items I use most often.

You claim that this app is "completely free," but here I am using it and getting video ads every minute. But you tell me if I want to get rid of the ads, I have to pay $4.99. I call false advertising. If this app was legitimately "completely free" I wouldn't have to pay to get rid of ads. Yes I understand that you need to make money, but I feel like this app is shoveling ads down my throat to force me to buy the "premium" that's only useful for no ads. It's annoying when I'm trying to solve too.

This is excellent for large amount different calculations, it is very well designed & free. Has made my life A lot easier!. Thanks.

Excellent App! Never thought apps like this would be so beautiful and useful at the same time! Thanks a lot for making such a beautiful app!

Exelent app it basically have everything you will ever need in eny calculation The ads are just on the bottom of the screen so no annoying popups, i totally recommand it

Tried this app thank to Google Play Pass. Wow! This is alot better than the other calculator app I paid for! Great job, just replaced it as my main calculator!

app is exceptional, best there is. Don't like the small advertising at the bottom. Only 3 stars because 2+2x3 does not equal 8 seems a error on most calculate apps

Exceptional design, fair price. I never thought I'd pay for a calculator app, but you lot have proved me oh-so-wrong.

I forgot to bring my calculator during add maths tuition. I had no choice but to download a scientific calculator. I thought it would be ridiculous because I'm using the 'phone calculator'. Fortunately it worked perfectly but kinda took some time to be familiar with all the options. I gave 4 star because I still can't find the options for Tan-¹, Sin-¹ and Cos-¹. Thanks!

Does everything you expect from a calculator... It has a lot of features on the free version... I imagine tthe pro version to be even better...

Equation solver ia not working and ads are not stopping to come. Which is very irritating. Otherwise it is a good app.

Undoubtedly, the best one. If Finance Section includes Return on Investment [ROI ], Rate of Return [ROR] and Equated Monthly Installments [EMI], it would be terrific. These calculations are done by everyone often before investing and trying to know how much to save from earnings.

Awesome App! I love this one. It has all the conversion I need. Keep up the good work team.

The All-In-One Calculator does much more then I need but from the functions of the app used, it works very well. It's nice to have all of the conversion options and a simple calculator in one app.

such an amazing and interesting app I have ever seen in my life.. very helpful for all generations and can be used in all aspects of life.. 😍😍😍

At the first glance a bit complicated, but after short time (1 day) incredible!

Really extensive! There's almost too many choices. 😁 It's really worth taking the time to set up your favourites to enable quick access to the ones you use the most. Unobtrusive adds is another bonus, as well as a Dak theme.

Good has pretty much everything you need. It is missing some measurements though which is like to see added

It's great. Easy to use and the ads are very minimal.

Works OK but needs more basic functions - like clearing memory in basic mode. Available in scientific mode.

I dont like it because i would take a picture of math and it says temporlarily cannot figure out. And you have to watch videos befor taking a picture

I payed for the full version after a few months of use and there is no better app on the play store, perfect

Love the vast features especially themes, finance, health etc... sure to recommend it others. 5 star guys, you earned it

I hope you guys add a method by which we can see how much money we can save from " percentage "offers. Btw it's pretty handy. So luv it

Complete. Very easy to use. Convenient. Covers the basics well.

Excellent design and easy to use Calculator and Converter. Absolutely worth it !

This calculator has any type of calculation function you need. Finance, measurement, conversion, algebra, trigonometry, currency, whatever the need. Simply an awesome and fully loaded calculator app. Well done to the developer.

I love the versatility of this app and the low key ads aren't bothersome at all.

Very useful Variety of features helps a lot! It also has a widget to get things done quickly

Its superb and so so amazing I advise all the intermediate and matric students to use once this at home for thier better learning ! I definitely like this app so much

This is really helpfull thank you very much. I think this app will help thousands of students/people! Im just glad that i found this app.

great app I'll be using the ordinary calculator, currency and imperial to metric conversions. so far replaced 3 other apps. 3 for 1, that's pretty good Had it now for a couple months, more valuable all the time!
