Reviews From google play store

Amazing calculator. It must of took you awhile just to input all this code in android studios. You are awesome. The only thing i didn't like is my personal information by 3rd party to identify me and who know what they would do with this info. Other than that....great app. But i had to uninstall it due to this policy, Sorry. 😞

If you dont have this app. then its your loss. Saves so much time when im Tinkering. Even with friends in conversation, a Quick look and heres the answers on how to make whats needed. Love this app. Thank You for your work here. Im shure it will change my life. Some sort of global pinpointed time would be sweet.

I wish apps like this would replace the bulky and expensive TI calculators. Teachers need try to learn to trust the machine and stop making students spend extensive time trying to do this stuff by hand. Especially conversions.

I love this package. I love being able to make shortcuts to specific calculators, I've got the mass converter attached in my soapmaking folder for easy access. Tip calculator on a secondary home screen. Great app.

I use this app a lot, and i'm very happy with it. It does everything advertised, and has accurate results. My only criticism is the menu layout, some conversions are a little difficult to find, but that's no big issue, and not something i would remove stars for. Another thing i like is that the conversions are in a list, and when i add a numberbto the item i want it converted from, and it shows the results for all items listed. I highly recommend this app. If i could, i would give it 10 stars.

This calculator is really amazing. Aside from its many calculation tools, you can also create your own by just few editing of formulas found in its Custom Tools. It's really cool, since I'm fond of calculations using MSExcel and it takes some minutes to open it, and now, I don't need to open an MSExcel anymore. Because, now I found this amazing calculator. I hope, you can make it more featurable. Thanks.

A superb tool for everyone! I am blown away! Never seen such a fully loaded calculator. They left nothing out! Its awesome! A wonderful tool for any problem or calculation in the world! If you dont love math or knowledge you will after downloading this ALL IN ONE + MORE...❤ The developers really went all out on this. Easy to use. Simply go to settings and thats where the magic begins... More calculations than I've ever seen in my life!! A-Ok. This is splendid... 😊

NEED ablility to choose numerical width and hight of floating calculator. Currently 54x46 bip minimum. Want short and wide 45x60? NEED to see fraction and decimal results at the same time! NEED rarer meassures and conversions. Conversions and the calculator on mini? flip botton? Ex: food: $ or €/lb or g. It is the best I have found for everyday and business uses. _ Excellent pairing with "keyboard with ctrl key". it goes from 30 to 100 bip!

I love that I can create custom tools. This is a wonderful app, love it!

Could be the best number calculations app there is but for me it is not since your app makes a separate slot for the calculator wasting valuable home screen space. Currency converter can't be updated which is another annoying thing

The best thing in the world! ALL of anything and everything you use every day that is hard to find in normal information books. LOVE IT!

Great engineering app. Most commonly used conversations and base line information in my pocket.

Love the tool kit. Keep adding more and I'll keep throwing money you

It's a nice App with a very clean and customizable UI which I really like!

Exceptional, the programmable part is a jewel on the crown

An excellent App, covers the majority of formulae for anyone. Nice to come across people with a bit of thought. Can't thank you enough. ☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆

Absolutely AWESOME. Amazing. BEST programming.

All in one is all you need. Great app, thank you for this.

That fact you can create you own conversions equations is novel and brilliant.

Could not get it to do Unit Converter, I tried several times, not with my finger, but with a pen, which is more accura It kept going to Electronics. It would be useful to have a ToolTip so you don't have to figure out when exploring, what an option is for, e.g. couldn't get out of Electronics, & clicked on what turned out to be a shortcut it created for Electronics. It doesn't seem to be user friendly. I don't understand why it has s 4.8 rating, when I can't get it to do what I need.

Superb. Essential app for all engineers.

Cool app usefully useful at times.

Unbelievable amount of different calculators, you will find what you are looking for! If you don't install it it's your loss.

Perhaps the best calculator I have ever tested ... Suggestions: - Option to open always as Calculator - Swipe to access faster to Favorites - Allow add "Custom Tools" to Favorites

thats for the ads update impovement to the basic calc.... Simple fix don't upgrade 😛 I can't even remember seeing ads before and I have used it for years !

This is the BEST calculator I have EVER used. Kudos to its creator. Well thought out and very easy to use.

Nice complete calculator. Missing a few key features such as engineering notation and several financial functions such as IRR, PV, FV, PMT

Brilliant! More than I know how to use. Easy to access the bits I need.

Excellent tool--very useful!

Does everything I want! Basic calculator, geometry calculators, unit conversions...I guess the only thing missing is a ft-in calculator where you can do calcs by putting in the feet and inches separately.

Good and useful multitool.

Very good calculator for many things

Lots of awesome tools.

Great tools, love it for engineering and general use.

excellent.. very usefull and efficient tools. thanks

This is great, simply the best so far.

Good general purpose app

Amazing apps. One of my favorite apps. Thanks a lot 👍 😍

good calculator app. would like it better if it had base conversions (decimal/hex/octal etc)

Easy to use and does the job

Please include mili Bar in pressure converter

Awesome app! I like to be able to convert measures for a lot of everyday things like cooking, temperatures or miles and usually I will do an online search and have to hop around until I find a simple answer without having to read a page of text that goes along with those converter(s). This app in contrast puts everything in one place. Pretty simple to use after exploring all the things it has to offer, which is a lot. Very good time saver. Highly recommended!

Superb app. Really it is all in one

Nice app. The UI layout can be improved a bit, and I wish there was dark mode.

Perfect for all work

I love working with math. but, unfortunately, I can't add 2 numbers together. the tools in this app give me a broad reach beyond just my fingers. unit conversions, equation solving, geometry, trigonometry, the list is extensive. thank you developers!!!

I am a brake operator in a fab shop, I find this app highly useful for that and many other daily tasks. I just would like to write and save custom formulas for brake work, etc. in the calculator.

fantastic. can perform complex calculations yet easy to use. being able to write your own algorithms is a beautiful touch. well done team x

I Really don't like that it does NOT rotate on my LG Android phone to landscape. Also, why couldn't you include a proper history that's truly a functioning long term history. One that can be managed, that way delete everything IS NOT the only option. It's far more efficient to retrieve equations/formula's and results from history then trying to recollect, rebuild and re-calculate from scratch. AND, When assessing what-if scenario's, retrieval of historical work & data saves time and money!

Good app, but the currency converter ( in Finance) is not really accurate, because the app does not update to the current market value. No manual or automatic currency update. Last update in my phone was since June 2018. Couldn't get it to update to the current currency value.

Very versatile calculator and converter! Nice feature to add a favourite button to the home screen. I'd like to have a Dez / Bin / Hex / Oct conversion option directly in the main calculator. This feature is hidden in the Numbers conversion and it would be helpful to have available all the time.

OK calculator and with many useful tools and converters. Suggestion: in currency converter perhaps the ability to update manually or change the source of exchange rates. Also with this price maybe dev should consider enabling the family library feature. EDIT-1: yes dear dev I know how currency updates work. I suggested an addtional drag down to update and also alternative sources.

fantastic app. so many tools all in one. I use RPN Calculator and Currency convertor almost every day

This calculator/converter has everything you could possibly need from a calculator and can convert about anything you can think of, including electricity. I don't know much about electricity, but if you need to do something dealing with electricity, it's definitely worth a try. You can choose calculators/converters as favorites too so you can find your most frequently used calculators/converters easily, which is a great feature 👍🏻

i have absolutely loved this app. There are so many functions in it. A lot are way my head but when i showed it to a couple electricians they downloaded it immediately. Definitely a app worth 5 stars.

Wow, everything you ever need, nothing like it out there.

Needs more financial functions to work better. Needs at least a loan to interest function to show monthly payments. Advance financial functions would also be helpful. Nice design but lacking, compared to some others.

It is a fantastic app. If there is something you need but it does not have it .... you can add it yourself. So, basically it can convert/calculate anything.

Using it for years. Great help from app writer when there's a error/problem. Can write your own formulas for special conversions. Can add shortcuts to home screen. Love it

Very good starting point for beginners and also features for the experienced the every day service technician. Thank you Ivan for your time, experience, and sharing your knowledge.

It will be great if you could add Time Calculator (HH:MM:SS) to the app.

This is the all in one app I've been looking for! It puts all the physical/dimensional measurements AND electronic formulas I use on a regular basis in one solid app.

Easy to use. Like the layout and has what I need. Really like how adding a value convert's it for outher units. It's also fast and ads are not in the way.

Great tools in it. I love the fact that you have a set of many of the most used tools for all the problems related to mathematics, engineering and other branches of knowledge.

For any engineering student, handyman, or tech this is a must have app. Very well thought out and includes almost everything you can think of. Great app!!

Excellent and very useful, handy and easy to use.

Fantastic! Much needed and now allin one app. Thank you

wish there were more Stars i would've given more, it is what it says All-in-one, surprised to see some of the calculators, must have taken alot of hardwork to arrange all these convertors. bravo!

Took some time and response from developers to figure out the trigonometric functions. Unit converters are good and plenty. A great app!

quite the unique tool to use

A very complete app. Has a converter calculator for almost all units. I still need to test the accuracy of some of them. But so far so good.

So useful with a function packed Toolbox! A wonderful aid.

Hands down, this is the best and simplest calculator & conversion toolbox!

I only write reviews if the app is amazing!! and this one is but I would like to be able to colour the menus

I think this app is great. Gives me all the information I need and some.

Best calculator app available. So many additional tools for almost every conceivable situation.

Nice app but has some flaws

Great functional app. It works well and delivers with useful features. I have no problem using it.

custom calculator is an awesome tool. it helps to build custom applications. kudos to the team..

Very intuitive and easy to use. A terrific all in one tool.

Does everything it's supposed to do, plenty of options, love it!

Excellent app. Huge variety of tools. Fun way to explore number

Easy to use, covering most of the calculators and reliable 👍

It's good, but when you type large numbers such as 2^64, it would return values such as 1.8447E19 instead of the actual value.

Use it all the time. Needs a bit more finance and statistical calculations....

Stop comparing and hit the download button! easily the best calculator available for Android!

the all-in-one calculator has come in handy many time. I use it a lot in the field and shop b eing an engineer.

Needs an on demand and daily while charging updates for currency and it would be 5 stars.

Too much for my math skills! I see it has the potential for calculus , trigonometry , and exponential expression!

I dont have premium and ads want to take over. I need to buy premium. I guess.

Missing Basic Statisical functions, e.g. Mode (what number is most common) as opposed to average.

Has a lot in there, but have to be very careful with the advanced tools.

Does what it's supposed to do but does it very well. You can create shortcuts to the various converters which speeds things up considerably.

Very nearly the one tool that binds them all... highly recommended

So many options! I love the algebra and finance calculator options.

Great app very helpful when you are not very good at maths

its a bit slower than builtin Calculator, when you press the Number. but still deserves full 5star 🎉🙏

Best convertor out there. Great ui very easy to use and the price is right!

Easy to use, packed with lots of calculations!

works well. and, app can be moved to external SD memory!
